How to change silent blocks on a VAZ 2109

Replacing silent blocks of the front suspension of a VAZ 2109

Replacing the silent blocks of the lower arm of the VAZ 2109 front suspension can be classified as complex work related to the chassis. To resolve all difficulties, it will be enough to use a well-established algorithm, which is given below (photos are attached to it).

VAZ 2109 silent blocks - necessary replacement of important suspension elements

To dampen vibrations and prevent their transmission to the body of VAZ cars, special rubber joints - silent blocks - are used at the junction of the suspension elements with the load-bearing part.
These elements are consumables and in case of severe wear they are simply replaced with new ones. VAZ-2109 silent blocks last an average of 50-70 thousand km, after which they have to be replaced. Moreover, both the front and rear suspension joints must be replaced.

Note that the indicated mileage is an average and it is impossible to determine exactly how long the hinges extend. Therefore, the suspension should be inspected periodically. Cracks, delamination, significant extrusion of the rubber layer in the hinge indicate an extreme degree of wear and the need for replacement.

Features of choosing silent blocks

To carry out the work, you first need to buy new elements. For VAZ-2109, you should select hinges according to the catalog number (2109-08-054). When purchasing, it is important not to confuse them with the hinges for the 2110 model, since the size of the silent block of the rear suspension of the VAZ-2109 is different (they are slightly smaller in diameter). Although it is quite possible to install a “tenth” element, pressing it in will be somewhat more difficult.

size of silent blocks of the rear suspension of VAZ 2109

As for the front end, you can purchase assembled VAZ-2109 front suspension arms (with silent blocks) and install them. But this is not economically feasible, since levers are much more expensive than rubber elements. And although replacing silent blocks is a more labor-intensive operation compared to replacing a lever, repairs will cost many times less.

rubber silent blocks and polyurethane

As for the choice of hinges based on the elastic material used, VAZ silent blocks can be purchased in both rubber and polyurethane. The latter have a longer service life, but they are tougher and more expensive. But in general, the car owner himself will have to decide which elements to purchase.

Note that you should only buy hinges from well-established manufacturers - SS20 DAAZ Corteco, etc.

Replacing rubber joints on the rear suspension

More on how things are changing. First, let's look at how to replace the rear silent blocks of a VAZ-2109. To perform the operation you will need:

Inspection hole;
Jacks;
Tools (key sets, hammer, attachments);
Bench vice;
Mount;
Spring ties;
Soap solution;
Pullers for rubber joints;

First, the silent blocks of the rear beam of the VAZ-2109 are replaced. For this:

We put the car in a pit, jack up the rear on one side, remove the wheel;
Unscrew the nut of the bolt securing the beam to the body, remove the bolt;
Using a pry bar, we press the beam down to remove it from the bracket, fix it in this position (by installing a wooden spacer between the beam and the body);
Using a hammer, carefully knock out the worn hinge;
Using a device (a long bolt with a nut, two wide washers and a piece of pipe), we press in a new element, having previously generously lubricated the seat and the hinge itself with soapy water;
We install the beam into the bracket and fix it with a fastening bolt;

After this, the silent blocks of the VAZ-2109 rear pillar are replaced:

Unscrew the fastening of the rack to the body (top) and beam (bottom);
We press the beam down so that the stand goes down and the spring relaxes;
Remove the stand;
Using a silent block remover, remove the hinge from the rack body (bottom);
We press in a new silent block using a vice;
We tighten the springs with ties, then put the stand in place and secure it;
Remove the ties;

Similar operations are carried out on the other side of the rear of the car. After assembly, you should check the tightness of all fasteners that have become loose. This should be done again after a couple of days of using the car.

We diagnose the condition of silent blocks ourselves

Machine creaks in the rear left side of the car body while in motion. The driver can increasingly hear a dull creaking sound, as if small and frequent impacts are being made on the rubber. They are especially activated when the car is overloaded and overcomes obstacles on the road, in particular high artificial bumps, or follows paving stones. The so-called “rubber” squeak is also detected at high speeds when performing sharp maneuvers. In such cases, an experienced driver will analyze the situation and think about how to change the front struts on a Passat B3, and what new equipment is worth purchasing. Problems should be diagnosed as soon as possible, because if, in addition to cracks and chips, ruptures appear on the silent block, then it is difficult to predict the behavior of the machine, and repairs will require large financial costs.
The creaking of a car without a running engine. The most common diagnosis among car enthusiasts is to park the car on a flat surface, go to the trunk and lift the body with your hands, holding the rear left wheel arch. And if you suddenly hear a creak, then one question arises: how to change the silent blocks of the rear beam of the Passat B3, who to turn to for help if you lack knowledge in the field of repairing foreign cars.
Deterioration in vehicle maneuverability. You notice that the brake pedal has become worse, as if it is falling somewhere, sluggishly responds to the driver’s demands, and sometimes does not work 100%.
Cracks and chips on the rubber inserts of the silent block. External damage is noticeable only during a visual technical inspection, when the car is on an overpass and there is an opportunity to evaluate everything in the inspection pit. It’s difficult to find, other equipment elements get in the way, but the task is still doable.

Silent block diagnostics
Thus, it is possible to recognize problems in a car if you are vigilant and want to keep your vehicle in good condition at all times. With the help of a specialist or on your own, it’s not difficult to figure out how to change the rear struts on a Passat B3.

Replacing silent blocks in the front suspension

Now let’s talk about how to replace the silent blocks of the front levers of the VAZ-2109. For this:

We hang up the front wheel and remove it;
Unscrew the fastening of the lever to the ball joint;
Unscrew the nut securing the stabilizer link and remove it from the lever;
Loosen the fastening of the lever to the body bracket and remove it from the car;
The silent block of the front lever of the VAZ-2109 can be removed in several ways - burn it out, knock it out or press it out with a puller or a vice;
We prepare the hinge seat - clean it of rust and rubber residues with a file. Afterwards, generously lubricate it with soapy water;
We make a small chamfer on the silent block and center it in the eye of the lever;
We do the pressing using a vice. We install the lever with the silent block between the jaws of the vice, align the position of the hinge relative to the hole, and then slowly tighten the vice, while periodically checking whether the hinge fits evenly.
After the silent block bushing rests against the jaws of the vice on both sides, remove the lever and finally seat the hinge in place;

After that, we put the lever on the car. We carry out a similar operation on the other side of the front of the car. After all work, check the tightness of the fasteners. Even if you do all the work yourself, you can complete it in 1 day.

When is it necessary to replace silent blocks?

If you hear a distinct knocking sound in the suspension while driving, you may need to replace the silent blocks of the front control arms on VAZ classic models. Upon inspection, they may be deformed, the rubber is torn or covered with deep cracks, and the lever moves from its original position. Silent blocks are not repaired; if they fail, they must be replaced, fortunately they are not expensive.

Damage to the silent blocks makes the ride less comfortable, reduces the level of safety due to deterioration in handling, as play appears on the arms, the suspension becomes looser and the wear of the front tires sharply increases, and this is another signal that the silent blocks of the front suspension will need to be replaced.

Purchasing a new item

So, you have found out that problems with the chassis are associated with the breakdown of silent blocks. Before starting work, you must purchase a new spare part. First of all, look at the labeling. It is important to buy an option specifically for the VAZ-2109. If you make a mistake, it will be impossible to install the silent block. The spare part must be marked: 2109-2914054. Many auto parts sellers may recommend purchasing a spare part from the “ten”, but to install it you will have to work hard to press the rubber part.

There are two types of silent blocks:

With rubber bushings. Traditional spare part, provides softness during suspension operation. The main disadvantage is the fragility of such a spare part, especially if you often travel along sections of the road with poor asphalt surface.
With polyurethane inserts. More rigid, which is its main drawback. Moreover, such a spare part lasts much longer, since it is resistant to temperature changes and deformations.

Choose a silent block based on material based on your budget and preferences. Manufacturers BelMag, SEVI, SS20 and Boge have earned good reviews from experts and car enthusiasts.

How is the replacement carried out?

Before starting work, place the car over a hole or drive it onto an overpass. Be sure to secure the wheels with chocks. Next, follow the instructions:

Remove the rear wheel. It will be much easier to work without it.
To replace the silent block you will not need to remove the rear beam, so do not rush to dismantle it.
When working on the left side, you will need to remove the linkage associated with the pressure regulator at the rear of the brake system. To do this, you will need to remove the handbrake cable from the mount located on the right side and the rod fixing bracket.
Using a 12mm wrench, unscrew the nut located on the rear beam mount. Here you may need to create additional leverage using a socket wrench that fits over the knob. After you remove this bolt, jack up the side of the car you are working on.
Carefully push the beam down until it comes out of the eyelet. Watch your actions, as you risk breaking the brake hose.
Prepare a wooden block in advance, which at this stage will need to be placed between the body and the eye. In this case, the beam should be below the eye.
Further work can be done with a special tool, but we will tell you how to dismantle the silent block without a puller. Take a metal tube and a hammer and use them to knock out the old bushings.
Clean the seat.
To make crimping easier, lubricate the seats with soapy water or dishwashing liquid. In this case, it is forbidden to lubricate the seats with oil or grease, since these chemical compounds will corrode the rubber part of the part over time.
Using a hammer or special tool, press the silent blocks into place. Reassemble the vehicle.

Upon completion of work, carefully tighten each silent block support. As you can see, this job is not difficult to do even alone. It takes no more than an hour.

How to replace silent blocks without removing the beam

Rear silent block VAZ 2110

The silent block is located at the bottom of the car. Even for the first time, you can easily replace silent blocks if you follow these instructions:

Raise the car with a jack.

Note: Place cardboard or an old blanket under the machine so you can easily work directly underneath it. This is not required if there is a special pit.

The beam does not need to be completely removed. After all, if you remove it, you will also need to remove the brake hoses. And this will take a lot of time. But it is better to unhook the brake sorcerer, since it may accidentally be broken during operation. And besides, it can interfere, since its dimensions are quite large. To remove it, you need to pull it, but this must be done as carefully as possible. Otherwise, you may “rip” it out, making it difficult to put back in.
You can unscrew the nut using a 19mm wrench. This is very difficult to do, so it’s better to call someone else to help. But if there is no assistant, then you will have to do everything yourself. To do this you need to press as hard as possible.

Note: it is advisable to spray the thread with water so that it oxidizes a little, and then clean it with a metal brush. This will make it easier to unscrew it.

Using a crowbar, you can lower the beam down, but do not remove it.

VAZ 2110 rear beam silent block and its replacement

You need to cut off the elastic band that is located on the beam, as it will also interfere. This should only be done if the rubber band is already old and not suitable for further use. Otherwise, you can not change it, but simply remove it. To make it easier to remove, you can drill a hole in it.
You need to lubricate the silent block and press it back.

Note: you cannot lubricate the silent block with grease, as it can corrode it. Therefore, it is better to lubricate it with soap or detergent.

Now insert the brake sorcerer back and screw the beam onto the bolt.

Replacing rear beam silent blocks on a VAZ 2109

Silent blocks produced by AvtoVAZ can safely be called one of the highest quality parts. It is not surprising that other foreign manufacturers also use them for their cars.

Element appearance

The durability of almost any part, including the silent block, directly depends on the driving style of the motorist. The service life of the element is more than 30 thousand kilometers.

Features of elements

The main function of silents is to eliminate vibrations and deformations that occur during vehicle operation.

When choosing new silent blocks for the rear beam of a VAZ 2109, pay attention to the markings. It should be 2109-2914054. For VAZ 2114-15 models, the markings are different, but the elements themselves are very similar.

In principle, it is possible to install a silent block from a dozen on a VAZ 2109, but you will have to work hard with pressing in the rubber bushing due to the difference in size. The reverse procedure is not possible.

Rear beam

Symptoms of a problem

There are several main signs of failure of the rear beam silent blocks, including:

Unstable behavior of the car on the roads;
Tires wear unevenly, which is not difficult to notice from the tread pattern;
When driving on a bad road (that is, 95% of all our roads), unpleasant squeaks and impacts on the car body are observed.

These signs are indirect, since they may be associated with other failures of the vehicle’s chassis. For example, dull knocks are also a sign of a faulty rear pillar. Therefore, in order to make sure that there is a particular problem, you will need to fully diagnose the chassis.

Reasons for failure of the rear silent blocks of the VAZ 2110

The rubber of silent blocks, cast with rubber-metal bushings, is capable of absorbing up to 300 kN of load, but if the part turns out to be of poor quality or the hinge is fixed in the wrong position, then its life will be short.
An aggressive and careless driving style contributes to the destruction of silent block rubber. When braking sharply directly on potholes or when jumping over tram and railway rails, the silent blocks are the first to fail.
Violation of the wheel alignment angles on a car also leads to the destruction of rubber-metal joints, and as a result, the suspension begins to knock.
Over time, so-called fatigue cracks begin to appear on silent blocks. They are usually identified by careful inspection of the pillows.

Required tools:

vice;
new silent blocks VAZ 2109;
liquid soap (can be replaced with detergent or soapy water)
source of fire (a gas burner is suitable);
a piece of pipe whose diameter allows free entry of the silent block;
standard set of keys;
chisel and hammer;
WD-40 penetrating fluid.

To work, place the car on a viewing hole or lift.

To replace the silent blocks of a VAZ 2109, as for other work, disassembly and dismantling are required.

Unscrew the lower lever. To do this, use a socket with an extension to remove the extension nut, as well as the fixation nut to the body. Then remove the stabilizer link and 2 ball joint bolts. To make it easier to work with stuck and rusted nuts, you need to warm up the connection or use a penetrating liquid. If these methods do not help, try unscrewing the crab, clamp it in a vice, and try again.

Secure the removed lever in a vice and use a lamp or torch to burn out the old silent block from its seat. If this option is not possible, you will have to press it out with a special puller or vice, but this will take more time.

Tools and materials

Tools you will need:

Spanners (take a full set at once);
Socket wrenches;
Vise;
Chisel;
Hammer;
Puller;
Silent blocks.

There are several important nuances:

to take silent blocks from repair kits intended for models 2108-2112 . You will simply waste your money because they are not suitable for the fourteenth VAZ model.

The easiest way to purchase a puller is at auto parts stores. But you can ask your friends for it.

You can make a device for pressing in a new silent block yourself. To do this you will need a 170mm M12 bolt, a bushing, a washer and a high nut. But if you have the opportunity to use a full-fledged, real tool, do just that.

You can begin installing new front suspension silent blocks. You need to treat the seat with soapy water and press it into the hole with a screwdriver (if you lubricate the hole with undiluted liquid soap, the resistance will also decrease). When everything is ready, you can start replacing the front suspension silent blocks with new ones.

After the silent block enters 50%, remove the tube and press everything to the end. There is no need to rush so that the part is not installed crookedly. You can add soap to make the process easier.

Check the protrusions of the silent block on all sides (should look like in the photo).

Replace the silent block of the "daisy" lever. The old ones need to be cut down with a chisel, and new ones installed in this place. Using a vice, press them into the mounting hole. Finish with a hammer and a pointer.

Reassemble everything in reverse order.
The actions on the other side are similar.
You need to tighten the nuts when the car is already on the ground.

Independent removal and installation of new parts on the upper arm

Work on replacing silent blocks on a VAZ 2107 without a specialized puller begins by placing the car in a room with a flat floor, and placing stops under the rear wheels, lifting it on a jack and removing the front wheel, after which:

It is necessary to remove the front bumper, which is attached from the inside of the lower skirt of the engine compartment with four bolts. This is done because the bumper will not allow you to remove the upper arm mounting bolt completely, and in this case it will not be possible to change its silent blocks.
Having removed the bumper, a stop is placed under the lower arm, after which the car is slightly released from the jack, and the nut of the upper arm fastening axis is unscrewed, then the nut on the ball joint is unscrewed and, using a puller, the ball joint is removed from the steering knuckle. Next, by removing the bolt securing the lever, it can be dismantled.

The removed lever is clamped in a vice and the old silent blocks are pressed out of it, replacing which new ones are installed. This can be done either with a specialized puller or with the help of a hammer; the silent block is driven through the spacer with gentle blows into its seat in the lever.

After installing new parts, the upper arm is mounted in the reverse order. At this point, all work with the upper levers is completed and work begins on the lower ones. The important point here is that the nut on the axial mount of the upper arm is fully tightened only after the car is removed from the jack on all wheels; this is done to avoid excessive twisting of the polyurethane filler in the silent block, which can cause its rapid breakdown.

Replacing silent blocks of the front suspension of a VAZ 2109

In this article we will talk about how to replace the silent blocks of the lower arm of the front suspension of a VAZ 2109 with your own hands. Replacing silent blocks is a more complex job related to the chassis. However, if everything is done correctly (according to the instructions), problems and difficulties should not arise. To make it clearer, I am attaching informative photos to this guide for replacing VAZ 2109 silent blocks.
