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.

What is a silent block

New rear silent blocks of the VAZ 2109 car

This is a part consisting of one or two metal bushings of different diameters. Between them there is an elastomer (this can be either special wear-resistant rubber or polyurethane). The main purpose of the block is to connect the suspension arms and dampen vibrations that inevitably arise when the car moves. This part successfully copes with cardan, torsion and axial vibrations. It takes on all the impacts, thereby protecting the remaining parts of the car suspension from mechanical damage.

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.

Malfunctions

Often, replacing the rear beam bushings is due to the fact that defects arise in the design of the element. They are like this:

• The elasticity of the rubber element deteriorates;
• The rubber breaks;
• The central bushing is displaced;
• Rotations occur in the seat.

If problems are detected with the silent block of the rear beam, you will need to drive the car into the garage in the near future and replace the damaged components. Unlike foreign cars, changing the silent seal on a VAZ 2109 is quite simple and without outside help. Plus it costs almost pennies.

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:

1. Remove the rear wheel. It will be much easier to work without it.
2. To replace the silent block you will not need to remove the rear beam, so do not rush to dismantle it.
3. 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.
4. 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.
5. Carefully push the beam down until it comes out of the eyelet. Watch your actions, as you risk breaking the brake hose.
6. 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.
7. 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.
8. Clean the seat.
9. 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.
10. Using a hammer or special tool, press the silent blocks into place. Reassemble the vehicle.

Choice

Before you start replacing the silent blocks of the rear beam, you need to decide what exactly you will replace the old, worn bushings with.

We figured out the markings and realized that for the VAZ 2109 you need to take only those that are suitable in size and diameter for the rear beam of the nine.

Today, for the VAZ 2109 they offer two types of silents, differing in the material of manufacture.

The choice should be made based on the available budget. Rubber elements cost several hundred rubles less. As for manufacturers, we recommend paying attention to the companies SEVI, BelMag, Boge and SS20.

Required Tools

The first thing you need to do is purchase suitable silent blocks (see the article “Which silent blocks are better, rubber or polyurethane”). The simplest option would be to purchase a wear-resistant rubber part. But, in this case, you need to prepare for their rapid wear. Spare parts made from polyurethane are more durable, but they cost 3 times more. It is advisable to use original silent blocks. If desired, you can use a part from a VAZ-2110; they are considered more durable. You will have to tinker with the installation of such an elastic band; it is slightly larger in diameter and will not fit into place easily.

• Puller for silent blocks;
• Mount;
• Jack;
• Metal brush;
• Heavy hammer or small sledgehammer.

Repairing the rear beam of a VAZ 2109

The rear beam of the VAZ 2109 is an unreliable thing, and the owners of this car may have a large number of reasons to remove it. For example, the owner of a vehicle may hear unusual noises: grinding metal, quiet impacts, etc. These “special effects” will be heard in the rear of the VAZ 2109. The sound can be either constant or occur occasionally, for example, when there are bumps on the road.

1 — rubber-metal hinge; 2 — rear suspension arm mounting bracket; 3 — shock absorber casing; 4 — compression stroke buffer; 5 — casing cover; 6 — support washer; 7 — shock absorber cushions; 8 — spacer sleeve; 9 — shock absorber; 10 - insulating gasket; 11 — rear suspension spring; 12 — lever connector; 13 — rear suspension beam arm; 14 — shock absorber mounting bracket; 15 - flange; 16 — lever bushing

It is very difficult for a person who does not have the necessary experience to determine on their own what caused new noises in a car. This is due not only to a lack of practice, but also to the large number of variants of the problem. So, for example, a knocking stabilizer can “move” the silent block to the side, the noise can often be caused by bearings on the axle shafts - in general, there are many options. Therefore, to find out the exact problem, it is recommended to go to a service center and carry out the repair yourself.

Also check out

1. 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.

1. 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.

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

1. 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.

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

Worth checking out:

Useful tips

• Before disassembling the beam, you need to loosen the tension of the hub nuts and other connections that are tightened with a large torque.
• It is recommended to change rubber-metal hinges in a specialized workshop - this requires special tools, as well as experience in such work.
• The instruction manual states that the beams must be dismantled together with the brackets by unscrewing the three nuts holding them in place. But due to long-term use of the machine, the studs can rust and therefore easily crack. For this reason, it is recommended to remove the beam by disconnecting it from the brackets - it is better to let them remain on the body.

The beam is installed in place in the reverse order; there are no pitfalls here. After the car is already on the ground, you need to tighten all the nuts. It is also necessary to check everything after 80-100 km. After installing the beam in place, the brake system must be bled, the parking brake must be adjusted, and, if necessary, the camber and toe must be adjusted.

Important points

• It can be difficult to remove the silent block fastening nut (during operation it becomes very rusty and is often literally welded to the bolt). Therefore, it makes sense to put a 19 piece of pipe on the socket wrench. This will increase leverage and reduce effort.
• When moving the beam eye down using a pry bar, you should not be too zealous, since there is a brake hose next to it. If you apply too much force when moving the beam, this hose can easily be torn off.
• To fix the eye in the lowest position, you can use not only a mount, but also a wooden block with a cross-section of 4x4 cm (and many car enthusiasts find this a more convenient solution).
• Before pressing in a new one, it (as well as the place where it will be installed) should be generously lubricated. However, it is strictly forbidden to use oil or grease as a lubricant, since the oil will corrode the surface of the silent block over time. For lubrication, it is better to use soapy water, or even better, regular dishwashing detergent, which can be purchased at any hardware store.

As can be seen from this article, even a novice car enthusiast can replace the rear silent blocks on a VAZ 2109 car. And for this it is not at all necessary to go to a service center. All you need to do is be patient, strictly follow the instructions above and follow safety precautions.

Instructions

Tools and consumables

1. A set of new silent blocks for the VAZ 2109 car.
2. Set of socket heads with a wrench.
3. Set of spanners.
4. A puller for rear silent blocks (you can buy it in a store or make it yourself).
5. Metal brush.
6. L-shaped mount.
7. Jack.

Sequencing

1. The wheel of the car, near which it is planned to replace the silent block, is jacked up and then removed using a set of socket wrenches (in principle, the wheel does not need to be removed, but then the work will not be so convenient).
2. Once the wheel is removed, the rear beam, lever and the block itself will become visible. This entire assembly should be thoroughly cleaned of dirt and rust using a wire brush.
3. Since we will not remove the rear beam, we should unscrew the mounting nut by 19. It is located directly behind the wheel. This nut and bolt secures the rear beam to the arm.
