VAZ 2109: replacing the support bearing with your own hands

Print this article Font size 16

The journal bearing is a component of the strut support. Belongs to the category of rolling bearings. Widespread use in domestic auto production is due to its versatility and ability to withstand heavy loads.

The main task of the OP is to dampen road vibrations. It provides a movable connection between the body and the vehicle's shock absorber. Plus, it affects the wheel angle settings of the VAZ 2109.

Element appearance

OP is the most important element in the design

Replacing a support bearing for a VAZ 2109
As you know, a support bearing or OP, as we will call it in the future, is designed to perform certain functions. Its main task is to rotate the stand around its axis. The OP is located in the front suspension and on a front-wheel drive car, such as the VAZ 2109, however, as on a rear-wheel drive car, in fact, it is the most important link. Before we move on to the direct algorithm for replacing the OP, we will find out important information regarding this bearing. So:

• The VAZ 2109, like all modern cars, has in its design not only an elastic, but also a damping device called a shock absorber to control movement. This is one of the main components of the front suspension.

Note. The shock absorber strut is designed to dampen vibrations that inevitably occur when the vehicle moves, even on a perfectly flat road. It is the strut support that dampens vibrations. The stand itself is fixed with its lower end to the steering knuckle, and with its upper end - to the mudguard of the car.

• OP is an integral part of the rack support. These parts belong to the group of rolling bearings. They have found wide application in domestic mechanical engineering due to many advantages, among which I would like to highlight versatility, the perception of combined loads and much more.
• The OP is directly involved in damping road vibrations, or, to put it differently, in damping and amortizing the VAZ 2109. In this case, the OP makes a movable connection between the shock absorber and the car body, simultaneously influencing the accuracy of the wheel mounting angle settings.

OP Features

Replacing support bearings in a VAZ 2109

The OP still differs from the standard rolling bearing, although it belongs to the same group. Here, the role of rolling bodies is always cylindrical rollers located perpendicular to each other. In addition, each of the rollers is protected from contact with each other by a special separator. Thus, each of the rollers acts as a separate element, independently taking on loads from different directions.

Replacing support bearings for VAZ 2109

In modern cars, such as the VAZ 2109, the following types of OP are usually used:

• A bearing with a built-in ring (it can be internal or external). This type of bearing is equipped with mounting holes and does not require pressure flanges. In addition, this type of OP has built-in gaskets that ensure constant rotation accuracy. This type of OP is used for both rotation of the outer and inner rings.
• There is another type of OP, which is equipped with a detachable inner ring for rotation of the outer one. The outer ring in this type of OP is in contact with the body. This type of OP is used where precision rotation of the outer rings is usually required.
• The third type of OP is a bearing with a detachable outer ring for rotation of the inner one. In this type of OP, the inner ring is in contact with the body, and the outer one is separated. It is used where it is necessary to ensure the accuracy of rotation of the inner ring.

• The fourth type of OP is called single-split. In such a bearing, the outer ring is divided at one point, which is why the rigidity of the entire bearing increases. It is again used where it is necessary to ensure high rotation accuracy of the outer ring.

Basic rules for using OP

As a rule, malfunctions of the strut support are detected while the vehicle is moving. If there is a problem with the strut, a characteristic knocking sound can be heard, especially when driving on a rough road.

Note. If such a knock occurs, it is necessary, first of all, to check the reliability of fixation of the support and if it needs to be replaced, then not only the rubber damper, but also the OP is replaced at the same time.

So:

• The OP is subjected to enormous loads while the car is moving, because it is this element that restrains the rebound movement of the shock absorber. Because of this, this bearing is checked every 20 thousand kilometers for malfunction, and every 100 thousand kilometers requires mandatory replacement, regardless of the condition of the strut itself.

Replacing support bearings on a VAZ 2109

Note. Most often, the OP on the VAZ 2109 requires replacement if for its owner the main and daily road is a dirt road, or if he often goes to the country or into nature, driving through uneven bumps and potholes.

• The shock absorber strut support is equipped with a rubber-metal element, which becomes cracked during long-term use. The wear process of this element is also influenced by sharply changing weather conditions, oil deposits and other contaminants. In this case, it is advisable to replace this element so that it, in turn, does not affect the operation of the OP.

Kinds

For the VAZ 2109, several types of support bearings are used, each of which has its own characteristics.

Basic faults

When a support bearing fails, a knock resembling dull blows appears in the front part of the car in the area of ​​the pillars. Most often, such symptoms are observed when driving over uneven surfaces.

A knock indicates that the bearing has ceased to cope with its duties due to a violation of its integrity. This is caused by the destruction of its structure due to:

• exceeding the recommended resource;
• excessive dynamic loads;
• dirt and moisture getting inside the bearing.

However, knocking in the area of ​​the racks may have other causes. To check the bearings and make sure that they are the ones knocking, lift the hood of the car, remove the cover of the supposed “glass”, and place your palm on the upper shock absorber support.

Rock the car up and down. If at the same time you hear the same knock and feel the corresponding vibration with your hand, immediately replace the bearing.

Conclusion

Having gained an understanding of what a support bearing is, how this part works and what problems can arise if its wear is ignored, every motorist will begin to listen to the movement of his car while driving and when cornering. If you hear a characteristic knocking sound coming from a wheel, don’t be too lazy to go to a service station or service center and carry out a small diagnostic of the chassis, this way you will save yourself time and nerves, and your VAZ 2109 will thank you.

Examination

Checking the support bearing should become a routine activity for you. It should be performed not only when an element fails, but also simply as a preventative measure.

Element in parsing

The manufacturer recommends checking the condition of the OP on the VAZ 2109 every 15-20 thousand kilometers. Although experienced drivers who have experienced the delights of our roads understand that checking is required a little more often.

To assess the current condition of a journal bearing, follow these simple steps:

• Turn off the engine, turn on the handbrake, put chocks under the wheels;
• Raise the hood;
• Remove the lid of the glass. It is located on the wheel bearing;
• Touch the support bearing with your hand (palm), and ask a friend to rock the car in different directions. Or vice versa, how it is more convenient for you to distribute the roles;
• Observe whether the stand “plays” during such manipulations;
• If knocks, squeaks, and crunches are observed when the car is rocking, then the OP has almost certainly outlived its usefulness and requires replacement.

If you find signs of support bearing failure, do not delay repairs. At best, you will break your hood, running into a hole and completely breaking the support. If the OP breaks down at speed, it can turn into a tragedy.

Comparison of old and new element

WE CHECK THE QUALITY OF WORK PERFORMED

When doing the replacement yourself, some skill deficiencies may appear. Somewhere a nut was not tightened or any of the elements of the rack were installed much crookedly. In order to avoid getting into an unpleasant situation on the road in the future, it is necessary to check the functionality of all the mechanisms that you touched when replacing the support bearing.

First, let's rock the car and check it for extraneous knocks. Be sure to check the operation of the brakes, since the caliper was removed during replacement. If everything is normal, you can start operating, not forgetting to check the wheel alignment settings, since it is also very easy to knock them down.

The support bearing on VAZ 2108-2115 vehicles is replaced on average once every 40 thousand km. If you do not want to endanger the machine racks, replacement must be done for preventive purposes.

Replacement

There are two main ways to replace the support. Choose the one you like, and we will tell you in detail about both options.

1. The first method involves removing the strut and steering arm together. This way you can maintain the angle of the wheels, that is, you won’t have to go and do a wheel alignment later.
2. The second method will require removing the shock absorber strut separately from the rotating mechanism. This leads to a violation of the angle settings, so you cannot do without visiting a service station to adjust the wheel alignment.

Bearings cannot be repaired, so the only correct solution is to replace them.

Now we will talk about each method of replacing a support bearing separately.

Replacement procedure

First way

1. Place the car on a flat surface, install wheel chocks under the rear wheels.
2. Place the gearshift knob in first speed mode and turn on the handbrake.
3. Remove the protective cap from the hub nut. The nut must be unlocked. If problems arise due to over-tightening the nut, you will have to pick up a drill and drill out the fasteners with the appropriate drill bit.
4. Using a 30mm socket and a long lever (to apply less force), rip the nut from its place and loosen the tension a little. But don't remove it completely.
5. If the nut does not budge, it may be caused by it rotating at the same time as the wheels. Therefore, your partner needs to press the brake pedal, while you remove the nut.
6. Next, loosen the wheel bolts and lift the car with a jack. Be sure to install safety bricks and pieces of wood under the thresholds. This will prevent the car from accidentally tipping over. Lower the machine onto the support.
7. Unscrew the wheel bolts completely and remove the wheel itself.
8. Remove the nut that sits on the steering knuckle.
9. Use a special puller to press out the steering pin. If you don’t have a puller, you can carefully use a pry bar and a hammer.
10. Remove the strut by unscrewing the three nuts on top and one long bolt on the bottom. After this, the old bearing is removed, a new one is installed in its place and the reassembly procedure is carried out.

Second way

Here we will do without wheel alignment adjustment. Therefore, the operations will be slightly different.

1. Remove the pair of bolts holding the ball joint in place.
2. Disconnect the brake line fasteners from the shock absorber strut. Before doing this, you need to remove the bolts that hold the caliper. Next, the working part of the brake mechanism is suspended from the suspension elements.
3. Unscrew the strut nut not completely.
4. Remove the three mounting nuts holding the shock absorber in place.
5. At the same time, unscrew the CV joint nut. Now unscrew it all the way.
6. Pull the grenade and remove the stand out.
7. The spring is removed from the rack using a puller.
8. After pulling the spring, unscrew the old, worn bearing. Place a new element in its place.
9. Perform the reassembly procedure.
10. When installing the hub nut, never use old fasteners. This nut is a one-time use component, therefore, after each dismantling job, it must be replaced with a new one.
11. When tightening the new nut, be sure to lock it after tightening.

Work is in full swing

Having a certain tool and at least minimal experience in self-repair will allow you to replace the OP on a VAZ 2109 with your own hands without any problems.

If you install 10th supports, then only with 10 racks.

Regarding better handling, reliability, etc. 10 supports compared to 08

And for history, if you asked for experience - please!

Here are your supports! Bet it, of course!

Polina, the affto in your profile is just garbage. Where did you get this brand?

I wanted to install SS20 Queen supports on the 15th, but they seem to only come in tens, on the Technology System website the difference between supports 08 and 10 is explained in 12mm, i.e. when installing SS20 Queen (-10mm) I will get about the same level in the front, (+12-10=+2) right? although here on the forum I also came across opinions that 10 supports are 40mm higher than eight supports, where is the truth? I am also interested in the need to replace some kind of upper cup, what is it called correctly?

Or forget about the notorious ammo rotation and take the eight-piece SS20 Master? ugh

Buyer's choice: cost of support bearing VAZ 2110, its manufacturers and articles

There are many different options on the market. It is advisable to take original parts - article number: RS-67499 or 2110-2902820-RU. The width of the part is 144 mm, length – 148 mm, and height – 62 mm with a weight of 1260 grams.

However, there are plenty of other options with good reviews. Among the well-proven products are parts from the Balakovo plant, as well as products from the Asomi company. The price fluctuates between 750 – 1800 rubles. When choosing a spare part, you should pay attention to the quality of the processing of the edges of the part, as well as the packaging. In addition, the part must have certificates of conformity and quality certificates.

What is this?

It is not uncommon for owners of the domestic “fourteenth” VAZ model to notice that a knock . The reason for its appearance is failed support bearings.

But you don’t need to start replacing right away. The first priority is to check the condition of the support. And only then take appropriate actions.

In analysis

There are several types of supports:

• A bearing with an integrated inner or outer ring. No clamping flanges are required for its installation. There are corresponding holes for installation;
• With detachable outer ring;
• With detachable inner ring;
• Finishing and cutting structure, the characteristic feature of which is its strong rigidity.
