Replacement of rear shock absorbers (for use on Renault Logan I, Dacia Logan I models)

The rear shock absorbers of the VAZ 2110 are characterized by an increased service life compared to the front struts. Typically, rear struts last twice as long as front struts. In this case, replacement of the rear shock absorbers on a VAZ 2110 is required if the following signs of malfunction appear:

• obvious knocking in the area of ​​the rear shock absorbers when driving on a relatively flat road and when driving over uneven surfaces;
• when hitting even small holes, the rear axle suspension “breaks through”;
• the rear of the car becomes less stable when cornering, braking, etc.

If necessary, you can replace the rear struts of a VAZ 2110 yourself in a regular garage. The procedure for replacing racks is not complicated, but a number of nuances need to be taken into account. Read more in our article.

Rear shock absorbers 2110: what you need to know

As with the front struts, the 2110's rear struts are needed to absorb energy and dampen road vibrations.

Shock absorbers also “press” the wheel to the road, which allows you to obtain the necessary stability, maintain controllability, and increase braking efficiency. As a result, the struts affect not only comfort, but also safety when driving a car.

It can be noted that due to the peculiarities of their operation, the racks increase the service life of individual parts and assemblies of the chassis. Due to the fact that the vehicle's stability is significantly improved, driving comfort is increased, and the load on the suspension and steering elements is reduced.

Due to the fact that the body does not jump in the pits, the braking distance is reduced, and the load on the braking system will also be less. It is also important to understand that on a VAZ 2110, the rear struts, like on any other car, also affect tire wear. If the shock absorbers are faulty, the tires will wear out much more actively.

Selection of shock absorbers

The choice of rear pillars should be approached carefully, since they bear the load when transporting goods, as well as absorbing poor road surfaces, which are quite common in the vastness of the country.

Signs of a faulty rear pillar of a VAZ 2110

As a rule, the main indicator that the rear pillar of a VAZ 2110 is not in order is the appearance of extraneous sounds when driving. Typically, faulty shock absorbers manifest themselves with a characteristic knocking noise from the rear. However, other problems can also cause knocking. For this reason, it is important to immediately understand in what cases the rear struts need to be replaced.

• It happens that the strut is normal, but the rubber bushings (silent blocks) of the beam are worn out and a knocking noise appears. In this case, replacing the bushings solves the problem;
• If a spring sags, such a spring needs to be changed (both together with the struts and separately);
• Often a knocking sound occurs as a result of loose shock absorber mounting or wear of the eye bushings;
• A rear knock may occur if the rear suspension is heavily loaded or there is a malfunction in the chassis on the rear axle;
• In the event that knocking appears only on uneven roads and regardless of speed, and there are no other reasons, there is a high probability that the rear shock absorber of the VAZ 2110 (both one and all shock absorbers) is faulty.

Replacement of rear shock absorbers VAZ 2110

In general, replacing a VAZ 2110 pillar with your own hands can be done in an ordinary garage with a minimal set of tools. Please note that shock absorbers only need to be replaced in pairs on one axle in order to eliminate differences in strut wear and obtain better vehicle stability.

It turns out that replacing the rear struts 2110 is a big deal. Even if one shock absorber is still functional, new struts must be installed on both the left and right sides. It is also advisable to change the springs in parallel with replacing the struts. Before installation on the car, the shock absorbers must be pumped! After pumping, you can proceed to replacement.

To replace shock absorbers you will need to perform the following steps:

1. remove the trunk trim to gain access to the rear pillar mounts;
2. remove the trim in the wheel arch and get to the upper shock absorber mounts;
3. Now the upper fastenings need to be loosened by unscrewing the nut with a spanner wrench, while the rod needs to be held with an open-end wrench 6.
4. Having unscrewed the upper fastener, we move to the lower fastener;
5. the rear of the car needs to be jacked up, the rear wheel removed from the side where the work is being done;
6. Next you will need to unscrew the lower fastener (nut 19) and then remove the bolt;
7. the next step is to remove the strut and spring, and also change the old rubber gasket (located between the car body and the spring);
8. You also need to remove the spacer bushing from the upper shock absorber rod and move it to a new shock absorber (without this bushing, the rear strut will begin to break up the seat);
9. It is also recommended to apply silicone grease to the rod to increase the service life of the entire structure;

During the reassembly process, it is important to secure the upper fastener gasket with double-sided tape, then install the rear strut into the seat (the spring should be in a stretched state). Next, all that remains is to put the lower fastening bolt in place, but do not tighten it.

Now a support is placed between the body and the rear beam, after which the car is carefully lowered from the jack, and the strut rod is directed into the mounting hole of the fender liner. It is important that the end of the rod appears in the trunk, after which the nut can be fixed and tightened. Now you can remove the jack and support and tighten the lower nut.

The final stage is a test drive. During such a trip, it is important that there are no knocks or extraneous noises while driving. First, the shock absorbers are checked on an unloaded rear axle, carefully driving over uneven surfaces.

Further, after 50-100 km, you can lightly load the rear axle by placing one or two passengers on the rear sofa or loading the trunk. If there are no knocks or noises, replacing the rear struts on the “ten” can be considered successful.

Recommendations

1. Please note that the rear pillar wears out much more actively if the driver carries cargo and a large number of passengers in the car. At the same time, wear increases significantly if a loaded vehicle is driven on a bad road (with a lot of potholes and uneven surfaces) at high speed.
2. If you need to change the rear shock absorber 2110, the replacement usually involves installing two new struts at once. It is important to understand which shock absorbers are best installed on the rear axle. Today you can buy gas, oil and gas-oil struts.
   In practice, it is better to install “softer” and quieter shock absorbers for the rear axle. For such purposes, oil or gas-oil struts are optimal. The former do not have a long service life, are not designed for heavy loads and can be knocked when cold, but they provide maximum comfort.

   We also recommend reading the article about which shock absorbers are better, gas or oil. From this article you will learn about the features of gas shock absorbers, as well as what are the pros and cons of gas struts.

3. The gas-oil shock absorber is stiffer and noisier, however, a car with such struts holds the road better, handling and stability are improved. For this reason, it is important to select the right replacement struts in advance, taking into account individual preferences, the characteristics of the vehicle’s operation, as well as specific goals and objectives.
4. If the rear strut of the VAZ 2110 and/or the spring fails, it is important to purchase only high-quality analogues for replacement. The fact is that cheap solutions can knock immediately after installation, and low-quality shock absorbers and springs often require replacement after 10-15 thousand kilometers.

How to determine if shock absorbers are faulty

Experienced drivers determine the malfunction of shock absorbers by how the car behaves on the road. After all, a car with faulty shock absorbers already at a speed of just over 70 km/h begins to “float” on the road, and overcoming bumps is accompanied by dull sounds.

To evaluate the front or rear shock absorbers, you need to swing the front or rear of the car, respectively, with your hands several times, pressing down on the edge of the body, and release at the bottom of the stroke. If the shock absorbers are working properly, then the edge of the body will smoothly rise from the bottom to the top without swaying. If, having reached the top point, it does not stop, but continues to swing up and down, then the shock absorbers on this side of the body require replacement.

Do not underestimate this type of shock absorber diagnostics as an external inspection.

If oil is leaking from the shock absorber, of course it needs to be changed. A bent rod and loud sounds made by the shock absorber during operation should also make you think about replacing the unit with a working one.

How to make sure the rack is working properly?

Sometimes it is impossible to visually determine the cause of extraneous noise when the car is moving. For example, the rear pillars of the Lada Kalina are clean, without any oil stains. Rocking also does not allow one to unambiguously diagnose a malfunction. However, the knocking noise in the rear suspension area does not disappear.

In this case, you will have to drive the car onto a vibration stand. It simulates road irregularities, and special sensors monitor how various suspension elements perform. The data is transmitted to a computer, which draws conclusions about the serviceability of the racks. This pleasure, of course, is not free, but it won’t hit your wallet very hard either. The cost of computer diagnostics depends on the region and is within a couple of thousand rubles. But for this money, the owner will receive data not only on the condition of the shock absorbers, but also all components of the front and rear suspension, which is especially important if there is a long trip ahead.

Purpose of the shock absorber on Lanos

A shock absorber is a damping element of a vehicle suspension. The devices in question perform several functions:

• Dampen vibrations of the car body and wheels
• Ensures smooth movement when moving
• Maintain wheel contact with the supporting surface

Damping devices are classified into two types - single-pipe and double-pipe. Depending on the type of damper, their design differs. The main components of shock absorbers are the following devices:

1. Cylinder - acts as a body
2. A piston that moves in a cylinder. The internal cavity of the cylinder is filled with oil or gas
3. A cylindrical rod with which the piston is connected
4. Fastening elements by which the part is attached to the vehicle suspension structure. On Lanos, the lower mount is presented in the form of a metal base with a hole, and the upper part is secured with a nut on the rod

The upper part of the shock absorber is attached to the car body, and the lower part is connected to the suspension arm or axle beam, which depends on the location - rear or front. The device is connected to the suspension using silent blocks.

What racks should I install?

This point needs to be decided in advance. It should be said right away that the rear pillars of the Kalina in a hatchback, sedan or station wagon are absolutely identical. Therefore, the choice is limited only by the manufacturer and spring stiffness. As for the manufacturer, experts do not recommend installing original racks due to their short service life. The most positive reviews and recommendations come from SS-20 brand products.

As for the stiffness of the springs, much depends on the driving style of the owner. Softer ones are suitable for leisurely drivers who prefer comfort to speed. If the car owner prefers an aggressive driving style, and the main use of the vehicle is on roads with good surfaces, then it is worth choosing stiff springs. This will improve the car's handling, although at the expense of comfort.

Very often, owners strengthen the suspension in the hope of giving the car some imaginary advantages. For example, they install stiffer rear struts on the Kalina. In this case, the station wagon body, according to repairmen, is capable of withstanding increased load capacity. Manufacturers are wary of such experiments. Increasing the spring stiffness creates additional stress on the car body. This is especially unacceptable for machines that have been in operation for a long time.
