Chassis VAZ 2107 front suspension. How to properly tune and strengthen the suspension of VAZ cars

07.10.2021

The original VAZ 2107 looks quite modest. Just as modest are dynamic characteristics car. Therefore, many car owners modify and improve almost all components and systems of the car: changes appearance, the interior becomes more comfortable, engine power increases, etc.

Radical tuning of VAZ 2107

You can turn a serial sedan that rolled off the assembly line at the beginning of the 21st century into a car that vaguely resembles the original with the help of tuning. Examples of professional tuning can be seen at various international competitions, for participation in which cars are specially altered and modified.

Tuning concept

The term tuning is literally translated from English as tuning or adjustment. Any car can be tuned to such an extent that it becomes unrecognizable. Each owner modifies his VAZ 2107 in his own way, determining individually which components and parts need modification.

Before you start tuning both the car as a whole and any component part, it is important to understand a number of simple requirements. Modernization of the machine should not contradict Russian legislation and regulations traffic(traffic rules). First of all, this concerns external body tuning, replacing wheels and rims, external and internal lighting. Everything that is attached to the sides and front of the machine must not: have parts protruding beyond the dimensions, be poorly welded or screwed, or contradict the requirements of UN Regulation No. 26.

There are three types of tuning.

  1. Technical tuning: improvement of engine performance, modification of gearbox, transmission, chassis. Sometimes this problem is solved radically - standard units and mechanisms are replaced with units and mechanisms from other car brands.
  2. Internal tuning: making changes to the interior of the cabin. The design of the front panel, seats, ceiling is changing, which are sheathed with fashionable material, inserts are made of metal, expensive wood, etc.
  3. External tuning: body modification. Airbrushing is applied to the body, body kits are installed, the configuration of sills, fender liners, etc. is changed.

Example of tuning VAZ 2107

The appearance of the VAZ 2107 shown in the figure has changed greatly due to an unusual homemade front bumper, sheathing, front fenders and sills painted green.

The ground clearance decreased from the factory 17 cm to 8–10 cm, which made the car look like a racing sports car and had a positive effect on stability and handling. The paint made the car stand out in traffic flow. Thus, external tuning made driving safer and gave the VAZ 2107 a memorable appearance.

Tuning the body of the VAZ 2107

VAZ 2107 is ideal for external tuning for the following reasons.

  1. The car initially has a discreet appearance.
  2. There is a wide selection of parts, accessories, and tuning accessories on sale at affordable prices.
  3. The car does not have complex electronics, automation, or self-diagnosis systems that could be damaged during work.

Most often, external tuning is limited to tinting the windows and installing stylish rims. Giving the VAZ 2107 body a streamlined shape is an almost impossible task. However for speed characteristics a car doesn't need it. You can reduce the force of air flow under the bottom by installing low-lying spoilers, which will harmoniously combine with the base of the body where the thresholds and bumpers are installed.

You can give your car a sporty look by:

Body kits and bumpers are made independently. It is very important to cut and bend them correctly. To do this, you can use special computer programs.

Windshield tinting

In accordance with traffic regulations, tinting windshield It is recommended to do it only at the top with a strip width of no more than 14 cm. This will protect the driver’s eyes from the sun’s rays. For tinting you will need:

  • tint film 3 m long and 0.5 m wide;
  • glass cleaner or shampoo;
  • rubber scraper for removing water;
  • napkins made of non-woven material;
  • marker;
  • a sharp thin knife (can be a stationery knife);
  • roulette;
  • spray bottle.

The tinting process itself is carried out as follows.

  1. The windshield is removed from the body and freed from the rubber seal.
  2. The glass is transferred to a bright, clean corner of the room where there is no dust.
  3. The glass on both sides is thoroughly washed with soapy water. Heavy stains can be removed using a solvent.
  4. The tint film is applied to the outside of the glass and traced with a marker to a tolerance of 5–7 mm.
  5. The film is cut along the applied line with a sharp knife.
  6. The protective layer is removed from the film.
  7. The surfaces of the glass and the adhesive side of the film are moistened with a soap solution.
  8. The film is applied to a clean, damp surface. In this case, the formation of horizontal folds should not be allowed.
  9. The film is carefully pressed with a plastic or rubber scraper from the center of the strip to the edges. At the same time, wrinkles are smoothed out. It is advisable to warm up the film with a hair dryer. There should be no bubbles between the film and glass. If they appear, they should be driven out with a scraper to the side that is not yet glued, or pierced with a thin needle.
  10. The glass is dried for several hours and installed on the car.

Headlight tuning

The simplest and most affordable way to tune the headlights and rear lights of a VAZ 2107 is to replace standard bulbs with LED ones.

To do this, they usually use a special tape with spotlights glued to it. This way you can make original running lights, angel eyes, etc. You can also purchase already tuned front and fog lights and taillights.

Tinting the rear window and installing a decorative grille

If the car owner does not have tinting experience, it is advisable to purchase the cheapest film for darkening. For rear window There are no restrictions on light transmission. Tinting is performed without dismantling the glass, since it is glued to the sealing gum. The work will require the same materials and tools as for the windshield. The film is glued from the inside in the following order.

  1. Glass is washed with soapy water, and heavy dirt is removed with a solvent.
  2. The tint film is applied to the outer wet side of the glass.
  3. Tinting is given the shape of glass. To do this, the film is pressed against the glass and smoothed out under a stream of warm air from a hair dryer. To avoid overheating the tint, the air temperature should not be too high. The hair dryer moves along the entire surface of the film, stopping in each place for 2-3 seconds.
  4. The protective layer is removed from the tint film, and it is glued from the interior to the wet inner side of the glass. Since the film has taken the form of glass, it should fit quite tightly. Water is removed from under the tinting using a scraper.

Sometimes, instead of tinting, a decorative grille made of two-millimeter plastic is installed on the rear window, which can be purchased at a car store. For ease of installation, it consists of two halves and is easily attached to the rubber seal of the rear window from the outside. The grille can be painted to match the color of the car or left in its original form.

Installation of roll cage

The installation of a safety cage will help protect the driver and passengers of the VAZ 2107 in extreme situations. Frame installation work is quite complex. In order not to disturb the geometry of the body, careful adherence to dimensions, welding and fitting of pipes in the cabin will be required using hand-held power tools.

Tuning the interior of the VAZ 2107

In the original it looks very modest. The lack of frills provides the car owner with ample opportunities for tuning. Before radical internal tuning, the seats are removed from the interior, the doors are dismantled and disassembled, the steering wheel, instrument and rear panels, as well as the floor and ceiling trim are removed.

Soundproofing of the VAZ 2107 interior

Internal tuning should begin with the installation of new sound insulation, without which there is no point in installing a high-quality audio system. During the installation process, preliminary preparations are made for tuning all interior elements. Depending on the readiness of the body surfaces, insulation can be installed either in parts or completely. External ones are processed first wheel arches and the bottom of the car, then the trunk, hood, floor and ceiling of the cabin, doors and instrument panel. After dismantling the engine, the partition in the engine compartment is insulated.

Required tools and materials

For soundproofing you will need:

  • set of open-end wrenches;
  • set of spanners;
  • set of heads with extension and ratchet;
  • construction hair dryer;
  • a set of screwdrivers with different blade shapes;
  • vibration-proofing material on a mastic basis (“Vibroplast Gold” or “Silver”) 4 or 8 mm thick;
  • Shumka (products of the Shumoff and StandardPlast enterprises).

Soundproofing the floor

Soundproofing of the floor is carried out as follows:

  1. The fasteners are unscrewed and the front and rear seats are removed.
  2. The factory coating is removed from the floor.
  3. The floor is degreased and treated with a special mastic.
  4. The floor is covered with soundproofing material.

Experts advise laying thin noise in several layers without gaps or gaps. Sound insulation is more effective than when laying thick material in one layer.

Front panel tuning

There are a lot of possibilities for tuning the front panel of the VAZ 2107. You can cover it with expensive material, make inserts from aluminum, chrome or valuable wood. For devices you can do LED backlight or install a GF 608 Gamma panel with an on-board computer. The steering wheel can be replaced with an analogue from a foreign car, covered with leather or other material.

Obviously, before tuning dashboard needs to be dismantled.

Replacement of interior trim and seats

You can effectively change the appearance of the interior by replacing the seat trim, ceiling, front and rear panels, and doors with more modern and practical materials. It is not recommended to use fleecy materials (phlox, carpet, etc.). When cleaning such surfaces with a vacuum cleaner, their surface will quickly lose its original appearance. To replace the seat trim yourself, you will need a sewing machine and the ability to operate it.

There are special inexpensive kits for sale for tuning the interior of the VAZ 2107, consisting of plastic decorative overlays for the dashboard, sun visors, armrests, door cards, acoustic grilles, etc. This kit can be matched to the color of the car and a variety of design options can be selected.

Seat reupholstery

The ideal option is to install more modern seats in the VAZ 2107 interior. Chairs from Toyota Corolla produced in 1993–1998, the fastenings of which coincide with the standard seat bolts of the VAZ 2107. However, it is quite expensive.

To reupholster the seats you will need:

  • material (fabric or leather) for covering;
  • foam;
  • glue “Moment” or equivalent;
  • electrical tape or tape;
  • sewing machine;
  • thick needle;
  • threads of a suitable color;
  • sharp knife;
  • awl;
  • set of wrenches;
  • hammer;
  • Screwdriver Set.

The work is performed in the following order:

  1. The front seat is removed from the guides and placed on a flat surface.
  2. The old sheathing is ripped apart at the seams. In this case, it is necessary to prevent damage to the edging.
  3. The places where the covering is glued to the cardboard inserts are moistened with gasoline.
  4. The old upholstery is carefully pulled off the backrest and seat cushion.
  5. Using scissors, a pattern is made from new material along the contour of the old sheathing.
  6. On sewing machine The sheathing parts and edging are sewn together with a double seam. Depending on the material, the joints can be stitched by hand, glued or heat welded.
  7. Foam rubber and sagging seat springs are replaced.
  8. The new upholstery is carefully stretched over the backrest and cushion of the front seat.

The rear seat is tightened in the same way.

Replacing door cards

Installing new door cards will also noticeably refresh the interior of the VAZ 2107. This is quite simple to do. Wood-like plastic overlays can be used as new cards. As an option, you can buy a set of various inserts for the interior of the VAZ 2107 in the store.

Interior ceiling trim

Some car owners attach hardboard to the ceiling of the VAZ 2107 and then glue the carpet onto it. This is quite long and laborious, but the result is very impressive. Before starting work, the windshield and rear windows are removed.

Sometimes the standard upholstery is replaced with leather or some other material. However, before this, the sound insulation of the ceiling should be strengthened. For this:

  • the factory noise is carefully removed;
  • the metal surface of the ceiling is degreased;
  • a vibration damper is glued to the degreased surface (experts recommend using a hair dryer);
  • a splen layer is glued onto the vibration damper;
  • the surface is covered with factory Shumka.

Other options for internal tuning of the VAZ 2107

Tuning the VAZ 2107 interior can be supplemented with:

  • replacing or modifying sun visors and rear view mirrors;
  • changing the interior lighting with the installation of footlights;
  • installation of a new radio and speaker system;
  • installation of electric windows;
  • replacing standard rugs with decorative ones;
  • modernization of other parts, devices and instruments.

Tuning the VAZ 2107 engine

The manufacturer installed on the VAZ 2107:

  • carburetor engines of 1.2 and 1.3 liters;
  • injection engines of 1.5 and 1.6 liters.

The most common types of power unit tuning are:

  • increasing the working volume of combustion chambers;
  • replacing the camshaft;
  • installation air filter zero resistance;
  • conversion of the exhaust system to a direct-flow muffler.

The greatest effect is achieved by installing a turbo kit on the engine.

Ways to increase engine power in a VAZ 2107

You can increase the power of the VAZ 2107 engine in the following ways.

  1. Tuning the cylinder head. Due to this, you can increase power by 15–20 hp. With. Since the head is made of cast iron, all operations to modify it are quite complicated and labor-intensive.
  2. Carburetor tuning. The diameters of the air and fuel jets are changed, and larger diffusers are installed.
  3. Installation of two or four carburetors.
  4. Installation of a turbocharger consisting of a compressor and turbine.
  5. Boring of cylinders to increase their diameter.
  6. Installation of forged lightweight pistons instead of cast ones.
  7. Replacing the standard air filter with a zero resistance filter.

On injection VAZ 2107 models, it is recommended to carry out software chip tuning. This will not only optimize engine performance, but also normalize operation electronic unit management. The effect will be maximum if chip tuning is performed on a working engine that has undergone a full technical inspection.

Tuning the exhaust system of VAZ 2107

Some car owners make the engine sound louder so that it resembles the growl of sports cars. To do this, the catalyst is replaced with a special flame arrester. Other VAZ 2107 owners believe that tuning the exhaust system is justified if the result is an increase in engine power. When assessing the feasibility of such measures, it should be borne in mind that improper installation will lead to increased fuel consumption and deterioration performance characteristics car. Therefore, work on tuning the exhaust system should be entrusted to professionals.

When tuning the exhaust system, do not forget that the maximum engine sound level should not be louder than 96 dB. Alteration of exhaust gas removal devices cannot worsen the environmental class of the engine.

Tuning the exhaust manifold and exhaust pipe

For better purging of exhaust gases, extreme sports enthusiasts replace the standard exhaust manifold with a StinGer spider complete with a double exhaust pipe (pants) made of stainless steel. This allows you to increase power at high speeds by about 9 hp. With. At the same time, the exhaust gas output formula “4–2-1” does not change.

Since the internal walls of the StinGer are smoother, installing such a manifold will increase the efficiency of exhaust gases and increase power at maximum speed by 9 hp. With

The smooth surfaces of the StinGer manifold flanges ensure a tight fit to the cylinder head and to the pants. However, the new downpipe does not have a threaded seat for oxygen sensor. Therefore, if necessary, a nut is welded on this pipe in front of the catalyst, into which the sensor is installed.

Since the pants end with a flange, the resonator of the injection model is attached without problems. However, on carburetor VAZ 2107 this unit is made differently, so it is better to immediately install a resonator from an injection engine on such a car.

Installation of a straight-through muffler

The standard VAZ 2107 muffler consists of two pipes, welded at different angles and lined with a non-flammable mineral wool filler, which reduces the speed of exhaust gases and softens the exhaust. To increase the volume of the exhaust and make the flow of exhaust gases straight, audio tuning of the exhaust system is carried out. Instead of a conventional muffler, a direct-flow muffler made by hand is installed.

In a direct-flow muffler, the exhaust gases do not make turns, which dampen the speed, and act as additional resistance, reducing engine power

Thus, with the help of tuning you can turn the VAZ 2107 into a completely new car. In accordance with the wishes of the car owner, almost any components and parts are modified, including the engine. Elements for tuning are available for sale, and most of the work is quite simple to complete, carefully following the instructions of professionals.

Everyone will enjoy a ride in the car seat. With a breeze, on a soft seat. No shaking or bouncing. Stop. What ensures such smooth running of the car? This is the job of a car suspension. Even VAZs have several types that are worth considering.

Front suspension VAZ 2107

On any make of car, the front wheel suspension is more complex than rear system depreciation. This is due to the fact that the front wheels are steering wheels, and unlike the strictly directed rear wheels, they have freedom of directional movement. In general, the front suspension of the VAZ 2107 chassis is quite powerful. It is designed so that it can be driven on roads that do not have asphalt surfaces. After all, this car is the latest version of the so-called classic VAZ series. It is the cheapest in the price range, and therefore most popular among residents of rural areas.

Front suspension device for VAZ 2107

Conventionally, the VAZ 2107 suspension can be divided into 4 nodes. Two triangular shaped levers. The bases, both levers, are attached to the car body on movable mounts. Between the protruding vertices of the “lever triangles,” a rotary lever connected to the steering is fixed with finger joints. Between the lower arm and the spar, a spring with a shock absorber inside passes through the opening of the upper arm.

To synchronize the suspension of the right and left sides, a bar is installed between them lateral stability, which, however, has a decent freedom of position. It is attached to the lower arms. Basically, this is all a modification of the front suspension of the VAZ 2101, then VAZ 2103, 2106. Preventive repair of the front suspension of the VAZ 2107 usually consists of replacing the ball joints and rubber bushings.

Rear suspension of VAZ 2107

The rear suspension of “classic” VAZ cars is directly connected to the rest of the chassis. The rear suspension of the VAZ-2107 includes a driving rear axle, which is connected to the car’s engine through a cardan drive and the rest of the transmission. The wheels are oriented strictly in the direction of travel of the car. These conditions determined the features of the rear suspension of the VAZ-2107. Like the front suspension, the rear suspension is a modernized version of the first VAZ model.

The figure below shows the rear suspension structure of the VAZ-2107. Number 1 shows the thrust spring between the axle (4) and the car body. Number 2, telescopic shock absorber dampening sudden vibrations. Transverse reaction rod 3 prevents the bridge from moving to the sides from the vehicle axis. Longitudinal rods 5 and 6 fix the position in the direction of travel. This arrangement of nodes allows you to compensate for road unevenness.

Front suspension VAZ-2110

Like any VAZ suspension, the front suspension of the “tens” is independent. The design of the front suspension of the VAZ-2110 is more complex than that of classic models. This is due to the fact that the drive power unit, goes through the gearbox to the front wheels. Therefore, VAZ designers had to solve the issue of not only distributing the load on the suspension, but also preventing it from interfering with the operation of the drive. Here, too, the entire scheme is the result of a phased modernization of the front suspension, starting from the first version of the front-wheel drive VAZ-2108 model. This option, as the most successful, remained in the variations following the “ten”.

Front suspension device for VAZ-2110

The suspension kit includes the following components:

  • lower arm;
  • hub;
  • spherical bearing;
  • telescopic stand with spring;
  • brake disk;
  • wheel drive;
  • stabilizing cross bar (on both wheels);
  • suspension arm with extension.

The telescopic stand plays a special role here. Now they are produced in several types. Liquid and gas struts. The operating principle of the rack is based on gradual, rather than sudden, movement of the working rod in the housing. This is achieved using bypass valves in the cylinder on the inner rod. Depending on the medium that the valves bypass, the struts are divided into hydraulic (liquid on oil) and gas. Typically, the manufacturer installs cheaper hydraulic struts. One of the positions for tuning the VAZ-2110 chassis is precisely the replacement of liquid struts with gas struts. They are more effective and provide stability to movement at any speed.

Rear suspension of VAZ-2110

Racks are also used here. But since there are no unnecessary problems in the drive image rear wheels no, everything is somewhat simpler. The rear suspension includes the following components and parts:



The supporting beam is fixed to the car body with a movable connection. That is, the beam has relative freedom of movement, like a lid that folds down. The spring and shock absorber successfully dampen sudden vibrations, eliminating sudden impacts of the beam on the body. The main malfunctions of the rear suspension system are usually also primarily malfunctions of the shock absorber strut. Also wear of rubber expansion joints in moving joints.

Attention! Whenever inspecting the chassis of a car, a repairman must check the condition of these parts.

Malfunctions of these components do not just cause unpleasant knocking sensations. They contribute to the destruction of the body. A body repair the pleasure is not cheap. It is better to replace the rubber bushing on the hinge or even the strut in a timely manner than to pay for body work later.

Suspension of the VAZ-2121 Niva chassis

The Russian SUV VAZ-2121 has all-wheel drive. This was also reflected in the suspension design of the vehicle's chassis. It has its own characteristics and slight differences from other models.

Rear suspension of Niva 2121

By her own rear suspension The Niva bridge is identical to the design of conventional classic VAZ models. However, the moving parts have a little more freedom of movement and are made with a large margin of strength for confident movement in terrain where there is no road surface. A new design element is the brake pressure regulator device. Depending on the position of the machine and rear axle, a lever attached to the axle controls the degree of opening of the rear brake valve. The rest of the suspension differs only in mobility and strength.

Front suspension VAZ-2121

The front wheel suspension is a little more complicated. The front wheels are both driving and turning. Here, too, a larger angle of free movement of moving parts is provided. Therefore, for stabilization, an elastic rod is installed, attached to the body. The upper and lower support arms of the suspension are made in an A-shape and are more reminiscent of paired suspension arms of a front-wheel drive car than a classic one. Despite the apparent fragility of the structure, its strength exceeds the strength of the “classical” structure due to the material and the thoroughly calculated form of rigidity. As with other suspensions, it is necessary to carefully monitor the condition of the rubber bushings and ball joints.

Telescopic suspension strut VAZ

To replace conventional shock absorbers, with the advent of front wheel drive cars VAZ received telescopic stands. They perform not only the function of a shock absorber in the suspension system, but are also an important element of the suspension’s load-bearing frame. If the shock absorber only softened jerks when hitting bumps or bumps, the suspension strut mounted together with the spring also prevents the car suspension parts from moving in different directions. Holds the suspension arms in a given position.

Therefore, all its parts are made of more durable materials than the shock absorber. Therefore, the price of the stand is much higher.

Design and principle of operation of a telescopic suspension strut

In essence, the stand resembles a medical syringe. The body is the cylinder of such a syringe. A rod with a piston at the end moves inside. Only in the absence of a way out, the liquid in the hydraulic struts is usually spindle oil, which, with the help of valves built into the piston, smoothly moves into top part when compressed. When stretching also

moves smoothly back. Unlike the shock absorber, the suspension strut body is equipped with cups to mate with a shock-absorbing spring, which provides additional stability to the suspension. In addition, depending on the type of strut, the lower mountings of the housing to the suspension arms are arranged differently. The strut is a non-repairable suspension unit. In case of malfunction, it can only be replaced.

Important! When replacing the strut, the spring is reinstalled on it. This can be done only with the help of a special tool - a spring clamp remover, in order to avoid serious injuries.

Brake system of VAZ cars

On the VAZ prototype, Fiat 124, the designers installed a disc brake system. It is ideal for highways and highways, those that in modern Russia are called federal. However, at that time, there were no roads of this level in the USSR. The vast majority of roads were of poor quality and did not provide opportunities for high-speed travel. And at low and medium speeds, disc brakes did not perform well. Therefore, a drum type was adopted, where semicircular pads were expanded hydraulically and pressed against the walls of the drum over a large area. So it became customary to install drum brakes on the classics. They didn’t split hairs by switching to front-wheel drive. The first “chisels” VAZ-2108, and after them 2109, were equipped exclusively with drums.

Switching to disc brakes

However, time passed, and the situation with the roads began to improve noticeably, the speed limit increased. Drum brakes were no longer doing a good job. However, installing a completely disc brake system meant completely eliminating the sale of new models to buyers from peripheral areas, where many roads still leave much to be desired. The “Solomon decision” was made - the rear brakes remained drum brakes, and the front ones were installed on discs. Since then, this formula has been fixed at VAZ. The only exception is the Lada Kalina Sport. This special speed model is equipped from the factory brake discs.

Tuning of VAZ chassis and suspension system

There are no special improvements when tuning the suspension of any brand. The usual steps in this direction are to replace drum brakes with disc brakes. But this is worth doing if a general modernization of the engine and gearbox has been carried out. You can replace some components with products made from lighter and stronger, and therefore more expensive, material. Another tuning point is to manipulate the length of the springs. Some owners, trying to give their car the look of a sports car, cut off 1-2 turns from the spring. Others, those who expect to carry heavy loads, on the contrary, “lift” the car with the help of special spring cushions, and even buy non-standard ones, with a large number of turns. Both options are unsafe. When trimming, “lowering”, the car loses a decent part of the depreciation, and the shock absorber strut fails faster. The body is destroyed and control deteriorates. When the body is raised, the car becomes less stable at high speeds and the risk of rollover increases. In general, suspension tuning requires careful thought and serious consultation.

In the video you can watch the repair of the front suspension of the VAZ-2107:

It must be said right away that the front suspension of the VAZ-2107 is of a double-wishbone type, as on most rear-wheel drive cars. It is necessary to carry out inspections from time to time technical condition all suspension components, as this affects the normal handling of the vehicle, as well as the comfort of the driver and passengers. Unfortunately, the quality of many components leaves much to be desired, so any element can unexpectedly fail. All work on checking and replacing suspension elements can be easily done independently. True, for diagnostics, for example, it is best if there is an inspection hole in the garage or an overpass.

Diagnostics of suspension condition

And now about how to carry out a technical inspection of a car, or rather its suspension, to identify faults. First of all, take a close look at the tires. They should wear evenly. If the rubber begins to wear off more on one side and less on the other, then the wheel alignment is clearly impaired. Besides, uneven wear tires indicates that there is a breakdown in the steering rods. Then what is needed is not repair of the front suspension of the VAZ-2107, but replacement of the steering.

Then you need to check the clearance in each of the front wheels. This must be done with the car parked on a flat surface. You need to grab the wheel, or rather its upper part, and then sharply pull it towards you. If the play in the bearings is very large, then you will hear characteristic knocking noises. Please note that the VAZ-2107 car has tapered bearings. They should have very little play. If adjusting the bearing does not help, you will need to replace it.

Checking shock absorbers

If the front shock absorbers are faulty, they must be replaced. If there are oil stains or deformations on the housing, new ones must be installed. Please note that a broken shock absorber cannot absorb all vibrations of the car body while driving. In this case, the front suspension of the VAZ-2107 will not work correctly. Before starting repairs, you need to carefully check the shock absorbers to fully ensure that they are faulty. To check how well the front shock absorbers work, you need to carefully, trying not to damage the wing, press on the front of the car.

If the shock absorbers are fully operational, the body will immediately return to its original state. If the body continues to bounce on the springs, we can conclude that there is a malfunction of the shock absorbers. It doesn’t matter whether one or both shock absorbers are broken; they only need to be replaced in pairs. It is worth noting that it is necessary to install new ones if there is an oil leak from the shock absorber cartridge. In this case, only repairing the front suspension of the VAZ-2107 will help.

Removing shock absorbers

First, open the hood, unscrew the nut that secures the rod to the car body. After unscrewing the nut, remove the washer and rubber gasket. Please note that the shock absorber rod must be held using a 6 key. But you can also use a special device. After this, unscrew the two nuts that secure the levers. The shock absorber is pulled down. Complete replacement VAZ-2107 front suspension is not required.

Please note that it will not be possible to remove it on a flat surface, even if the rod is completely recessed. It is necessary to slightly raise the entire side of the car on which the repair is being carried out. But the most convenient way, of course, is to do all the work on a lift or inspection pit. After removing the shock absorber, you need to unscrew the nut that secures it to the bracket. This bracket is installed on the new shock absorber.

Installing a new shock absorber

Next, proceed to install the new suspension element. In fact, all work is done in reverse order. First, a lower cushion made of rubber is put on the rod. Then the shock absorber body is installed in place through a special hole in the lower arm. The rod must be fully extended and guided into the hole in the body. This is how the front suspension of a VAZ-2107 can be easily repaired. The price of one shock absorber is on average 900 rubles.

After this, you need to install the rubber cushion and washer. Tighten the nut. At the bottom, tighten the nuts securing the bracket to the lower arm. After this, tighten the nut on the rod until it stops. The installation of the new shock absorber is completed, and similar repairs are carried out on the other side of the car.

How to replace the upper arm?

Lever Installation

Using a puller, the silent blocks are installed in their places. Please note that when installing the upper arm, which is done in the reverse order, it is best to use a new one. Also, do not tighten the nut with the wheel hanging. First you need to replace the bolt that secured the bumper, and then load the suspension.

If tuning of the VAZ-2107 front suspension is required, then it is best to install reinforced levers. For example, from Niva. Then install a spacer under the lower arm and lower the car on a jack. Next, you need to put the ball joint in place and only then tighten the nut. If you removed the ball joint completely by pressing the pin out of the hub, you also need to replace the nut on it.

Preparing to remove the lower arm

As in the case of the upper lever, the lower one is replaced when it is damaged. It is not necessary to completely remove it when replacing rubber-metal joints. Please note that a transverse rod is attached to it. This is exactly what the front suspension diagram of the VAZ-2107 looks like. To make repairs, you need to have 22 and 19 sockets, and a spring puller will also come in handy. First, remove the wheel and remove the spring along with the shock absorber. The lower ball joint is disconnected from the wheel hub and completely removed. After this, using a 22mm wrench, you need to unscrew both nuts that secure the lever to the car body.

Removing the lever

Using a 19 mm wrench, unscrew the nuts securing the transverse link to the suspension arm. Only after this is it necessary to move the axle using a mounting blade and completely remove the lever. Please note that under the axle on which the suspension arm is mounted, there are special washers. With their help, wheel camber is adjusted. Installing the new lower arm is done in the reverse order. New nuts must be installed. Using a puller, silent blocks are pressed into the new lever. That's all, the front suspension of the VAZ-2107 has been restored, now it will serve for quite a long time.

It is the front suspension that most often “takes the blows of fate”, being the most loaded component of the car’s chassis. That is why care and timely inspection of its main components, their repair and replacement will be the key to successful driving of the VAZ 2107.

The entire front suspension of the “classic” is more reliable than subsequent front-wheel drive modifications of the VAZ, since a car with rear-wheel drive has fewer parts in the front suspension, its design is more “economical”.

The design of the front suspension has important components, without which a smooth ride of the car is impossible.

Let us describe the design of the front suspension on the VAZ 2107:

  • double wishbone suspension, there are upper and lower arms that exist independently; the upper one is secured through the mudguard strut with a long bolt, the lower one is bolted to the suspension cross member, which, in turn, is connected to the front side members.
  • silent blocks, or rubber-metal hinges quietly. They are needed for the levers to turn. When worn out, replacement is required.
  • ball joints, or simply “ball” - to them through the system steering knuckle with the axle, the wheel hub is ultimately installed.
  • The shock absorption device includes a spring installed in the cups and a hydraulic shock absorber installed inside the spring.
  • The list of main devices is completed by a lateral stability bar (stabilizer).

The structure and most important parts of the VAZ 2107 suspension:

5 - knuckle axle; 9 - ball pin of the upper support; 10 - steering knuckle; 13, 36 - upper and lower arms; 17 - support glass; 18 - shock absorber mounting pads; 21 - upper spring support cup; 22 - axis of the upper arm; 29 - bracket for fastening the cross member to the spar; 30 - front suspension cross member; 33 - stabilizer bar; 34 - body spar; 37 - bolts for securing the lower arm axis; 40 - shock absorber;

This is what the pendant looks like from below. All structural elements are clearly visible (levers, spring, shock absorber, stability bar, balls, etc.).

What problems can the suspension have?

  • Drying and simple wear over time of rubber parts, boots, liners, seals, deterioration of ball joints, wear of the stability bar cushions;
  • “Fatigue” of the metal, which can cause damage to springs and shock absorbers.

The front suspension, unlike the engine, was luckier, since it is easier to carry out repairs in a home garage, and the design of the suspension is open. To do this, you need an overpass or a regular inspection hole.

What can be determined when inspecting the suspension?

  • The state of wear, crumbling, dryness of all rubber parts;
  • It is determined how dry the shock absorber is and whether there is any oil leakage from it, as well as evaluate its performance. The test scheme is simple: you need to sharply press on the surface of the car's wing and remove the load, that is, “release sharply”. A working shock absorber returns the wing up in one pass, without additional vibration.
  • The integrity of all coils of springs on the right and left sides;
  • The gap in the ball joints is determined.

Replacing ball joints

The work scheme (like all others) begins with cleaning the parts from dried dirt. You need to make it a rule to clean all the elements at the bottom of the machine before starting diagnostics and repairs. The most convenient way to do this is to first use a stream of water from the nozzle of a portable car wash, and then dry it with compressed air.

To replace the ball joints, first remove the wheels of the VAZ 2107.

The jack for loading the lower part of the suspension rests on the lower arm, simulating a “load” on the suspension.

  • Unscrew the ball pin nut (for example, the top one).
  • A special pressing tool is used to separate the steering knuckle and the support pin;
  • Unscrew the ball joint and remove it in its protective case.
  • A new support is installed and assembly occurs in the reverse order.

The lower support is also replaced. After this, the car is jacked up on the other side and the ball joints on the other side of the suspension are replaced.

After this, it is necessary to adjust the wheel alignment; this must be done at a service station on a special stand.

Silent blocks.

Let us recall that the silent block is a connecting element in the suspension of the VAZ 2107, and any other “classic”, which has an elastic liner made of polyurethane or rubber in order to soften the shocks of the suspension and vibrations. These parts take on large shock loads.

The figure shows the mounting diagram for the silent block of the lower arm.

Because of this, silent blocks are susceptible to wear, as a result of which the alignment is disrupted. It is advisable to change silent blocks every 50-100 thousand km. Mileage.

Replacing shock absorbers

The shock absorber is a non-separable paired part. That is, if one of them fails, then both change.

In order to replace the shock absorber, you need to carry out the following steps:

  • Unscrew the fastening nut on the rod;
  • Remove the washers along with the upper cushion made of rubber;
  • We unscrew the bracket with which the shock absorber is connected to the lower arm;
  • The broken shock absorber can be removed through the slot in the lever body;
  • The bracket is removed from the shock absorber and a new shock absorber is installed in the reverse order.

Replacing a broken spring

To replace the spring (which also cannot be repaired), you need to remove the shock absorber and disconnect it from the roll bar. After this, you need to loosen the screws of the lower arm, after that it is jacked up, then using a special puller we remove the ball pin.

The most loaded element of the VAZ 2107 car is the front suspension. Indeed, it takes on almost all mechanical loads that arise during movement. For this reason, it is important to pay careful attention to this unit, carry out timely repairs and modify it, whenever possible installing more durable and functional elements.

Purpose and design of the front suspension

Suspension is usually called a system of mechanisms that provide an elastic connection between the chassis and wheels of a car. The main purpose of the unit is to reduce the intensity of vibrations, shocks and jolts that occur during movement. The vehicle constantly experiences dynamic loads, especially when traveling on poor quality roads and when transporting cargo, i.e. in extreme conditions.

It is at the front that the suspension most often takes impacts and shocks. It is rightfully the most loaded part of the entire car. On the "seven" the front suspension is made better and more reliable than - the manufacturer, of course, took into account the high load on the unit, but this is not the only reason. On rear-wheel drive cars, the front suspension has fewer parts than the rear, so its design is less expensive.

The front suspension diagram of the VAZ 2107 includes important parts, without which the smooth movement of the car would be impossible.

  1. Stabilizer or lateral stability beam.
  2. Double wishbone suspension is the main chassis unit at the front, consisting of an upper and lower independent link. One of them is fixed with a long bolt through the mudguard strut, the other is bolted to the suspension cross member.
  3. Ball joints - are connected to the wheel hubs through axle-type steering knuckle systems.
  4. Wheel hubs.
  5. Silent blocks or bushings - designed for free movement of levers. They have an elastic polyurethane (rubber) liner that significantly softens the shock of the suspension.
  6. Shock absorption system - includes springs, cups, hydraulic shock absorbers. On VAZ 2107 models recent years release and on tuned "Sevens" struts are used.

Front beam

The task of the front beam is to stabilize the car when cornering. As you know, during a maneuver a centrifugal force arises, which can cause the car to roll over. To prevent this from happening, the designers came up with a transverse stability beam.

The main purpose of the part is to twist the opposite wheels of the VAZ 2107 using a torsion elastic element. The stabilizer is attached using clamps and rotating rubber bushings directly to the body. The rod is connected to the suspension elements through double levers and shock absorber struts or, as they are also called, bones.

Levers

The front levers are the guiding components of the VAZ 2107 chassis. They provide a flexible connection and transmission of vibrations to the body.

The levers are directly connected to the wheels and body of the car. It is customary to distinguish between both suspension arms of the “seven”, since their replacement and repair are carried out in different ways:

  • the upper arms are bolted, making them easier to remove;
  • the lower arms are screwed to a cross member connected to the spar; they are also connected to a ball joint and a spring - replacing them is somewhat more difficult.

Front shock absorber strut

The owners of the VAZ 2107 learned about the existence of racks when the VAZ 2108 model appeared. From that time on, the manufacturer began to gradually install new mechanisms on the “sevens”. In addition, the racks were chosen by specialists modernizing a classic car.

The strut is part of the shock-absorbing system, the task of which is to dampen vertical vibrations of the body, taking on some of the impacts. The stability of the car on the road depends on the technical condition of the rack.

The front shock absorber strut includes several separate elements:

Spherical bearing

A ball joint is an element of the front suspension that provides a fairly rigid attachment of the lower arms to the hub of the car. With these joints, the car on the road is able to provide smooth movement and the necessary maneuvers. In addition, thanks to these parts, the driver can easily control the wheels.

The ball joint consists of a pin with a ball, a thread and a housing with a recess. There is a protective boot on the finger, which is an important part of the element. Regular checking of ball boots by the driver helps to avoid breakdowns - as soon as a crack is detected on this protective element, the joint must be immediately inspected.

I remember how I changed the ball joints for the first time in my life. It happened unexpectedly - I went to the village to visit a friend. Exciting fishing was expected. On the way to the lake I had to brake sharply and turn the steering wheel. There was a crunch, then a knock, and the car began to pull to the left. “The ball has flown,” said Tolya (my friend) with the air of an expert. Indeed, when they jacked up the car, it turned out that the bull's-eye had jumped out of its socket - what a forceful blow it must have been! Apparently, the ball joint had also been subjected to heavy loads before this - I often went to the dirt road, and I didn’t spare the “seven”; sometimes I drove across the field, rocks and holes. Tolya went on foot to get new hinges. The broken part was replaced on site, and I then installed the second one in my garage. Fishing was unsuccessful.

Hub

The hub is located at the center of the front suspension structure and is a rounded part connected to the shaft. It has a bearing, the model and strength of which depends on the design tasks.

Thus, the hub consists of a housing, metal wheel studs, bearings and sensors (not installed on all models).

The steering knuckle is an important part of the hub, because thanks to this component, the entire front suspension is integrated with it. The element is fixed using hinges to the hub, steering tips and rack.

Front suspension malfunctions

Problems with the VAZ 2107 suspension occur due to bad roads. The first thing that suffers is the ball joints, then the struts and other elements of the shock-absorbing system fail.

Knock

Quite often, owners of the “Seven” complain about a knocking sound when driving at a speed of 20–40 km/h. Then, as you accelerate, the dull sound disappears. The area of ​​noise is the front suspension.

Experienced owners of VAZ 2107 claim that the knock on low speed, which disappears as you accelerate, is associated with the shock absorbers. They receive a vertical blow from below when the machine's movement is weak. At high speed the car levels out and the knocking noises disappear.

Detailed instructions for the actions of a driver who notices a knock are given below.


Video: what is knocking in the front suspension

The car is pulled to the side

If the car begins to pull to the side, the steering knuckle or suspension arm may be deformed. On old VAZ 2107 cars, loss of elasticity of the strut spring is possible.

Basically, if the car pulls to the side, this is due to brake pads, steering play and other third-party reasons not related to the suspension. Therefore, it is recommended to use the method of elimination, and only then test the suspension.

Noise when turning

The hum when turning occurs due to wear on the wheel bearing. The nature of the noise is as follows: it is observed on one side, appears up to a speed of 40 km/h, and then disappears.

Here's how to check a wheel bearing for play.


Suspension upgrade

The standard suspension of the “seven” is considered soft and imperfect. That's why many people decide to do tuning and modifications. This helps to significantly improve handling and overall comfort, as well as increase the service life of springs, balls, bushings and other elements.

Reinforced springs

Springs are the main element responsible for a smooth ride, directional stability and good handling. When they weaken or sag, the suspension is not able to compensate for the load, so breakdowns of its elements and other troubles occur.

Owners of the “Seven”, who often drive on bad roads or drive with a loaded trunk, should definitely think about upgrading the standard springs. In addition, there are two main signs by which you can judge that elements need to be replaced.


Spacers are the first thing that comes to mind for VAZ 2107 owners. But this conclusion is not entirely correct. Yes, they will restore the stiffness of the springs, but will have a negative impact on the service life of the elements. Soon cracks will be found on springs reinforced in this way.

Therefore, the only correct solution would be to replace conventional springs with reinforced ones or modified ones from the VAZ 2104. At the same time, it is necessary to change the shock absorbers to more powerful ones, otherwise the reinforced springs will easily damage the standard system.

Before you begin the replacement procedure, you need to arm yourself with the following tools.

  1. By lift.
  2. A set of various keys, including a cylinder key.
  3. With a tire iron.
  4. Bar.
  5. Wire hook.

Now more about the replacement.

  1. Place the car on a jack and remove the wheels.
  2. Remove struts or conventional shock absorbers.
  3. Loosen the upper arm clamps.
  4. Place a block under the car and jack up the lower arm.
  5. Unscrew the stabilizer beam fastening.
  6. Remove the lift.
  7. Loosen the lower and upper ball joint nuts, but do not completely unscrew them.
  8. Drive the support pin out of the steering knuckle using a pry bar and hammer.
  9. Secure the upper lever with a wire hook and lower the lower one.
  10. Use a pry bar to pry the springs from below and remove them.

Then you need to free both springs from the gaskets and check the condition of the latter. If they are in good condition, install the new spring using electrical tape. Install reinforced springs in place of the standard ones.

Air suspension

The “Seven” has great potential in terms of modernizing the front suspension. And many car owners decide to install an air suspension with an electric compressor, hoses and a control unit.

This is a real electronic assistant that allows you to change the value ground clearance depending on driving conditions. Thanks to this innovation, the stability of the car at high speeds increases, trips over long distances become comfortable, the car goes over bumps more smoothly, in a word, it becomes like a foreign car.

The system modernization goes like this.

Electromagnetic suspension

Another modernization option involves the use of an electromagnetic suspension. It is a set of mechanisms and components that serve as a connecting link between the road and the body. Thanks to the use of this type of tuning suspension, a smooth ride, high stability, safety and comfort are ensured. The car will not “sag” even during long-term parking, and thanks to the built-in springs, the suspension will remain operational even in the absence of commands from the on-board network.

Today, the most famous manufacturers of electromagnetic suspensions are Delphi, SKF, Bose.

The front suspension of the VAZ 2107 requires timely maintenance and control of the main components. Remember that road safety depends on this.
