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

Replacement of support bearings VAZ-2113, 2114, 2115

The support bearing, to the inner part of which the front strut is attached, and the body rests on the outer part, serves to movably connect the front strut and the body, softening all kinds of shocks and vibrations coming from the shock absorber. A timely replaced bearing will eliminate the problems of overhauling the entire chassis. When the hood is open, the support bearings are visible above the wheels on both sides.

Basic faults

Wear of the VAZ-2114 bearing is the main reason for replacing it. A knock in the suspension, which is heard when driving on a bumpy road or when turning, should alert the driver. Checking the bearing is simple: you need to grab it with your hand and rock the car; a knock that may appear indicates the need for repairs.

The dirt that is abundant on the roads is one of the causes of defects in the mechanism. The support is practically not protected from it.

It is worth checking the condition of the supports at least after 20,000 km.

If the knocking does not go away, then think about this: a completely worn bearing can break completely, and this will lead to the strut breaking through the hood. Repair costs will be completely different.

Replacing a bearing is not that expensive - about 500 rubles per part, 1000 rubles for a replacement at a service station.

The most popular bearings are ss20. They perform best under relaxed driving conditions, although some drivers complain about their harshness.

For a more sporty driving style, with sharp stops and fast accelerations, Acomi bearings have proven themselves well.

Don’t skimp on spare parts; try to buy support bearings from a trusted manufacturer. When choosing, you need to rely on your own driving style and the characteristics of the road surface.

Diagnosis of strut support bearing faults

A faulty bearing can seriously affect your car's suspension alignment. If it is not changed in time, the wheel camber will be disrupted, which will lead to wear of both the rubber and the shock absorber strut itself. As you know, driving on a faulty suspension can be unsafe.

To diagnose the condition of the support bearing, you need to grab the pillar with both hands, and ask a previously invited assistant to strongly rock the car in different directions. If a characteristic knocking sound appears during the swinging process, then such a part needs urgent replacement.

Replacement

• spanners;
• spring tie;
• jack;
• hammer;
• mount;
• a device for removing the nuts securing the stand;
• mechanism for removing the steering tip.

Work order

1. You need to remove the hub cap and rip off the CV joint nut while an assistant presses the brake using a wrench or socket.

2. Raise the car using a jack and remove the wheel. The factory stand should also secure the vehicle.
3. With the steering wheel turned in the opposite direction from the support being repaired, you need to release the cotter pin. To do this, use a hammer, a pry bar and a steering rod puller.
4. Remove the 2 ball joint mounting bolts.

5. The brake hose is removed from the holder.
6. Next, the 2 caliper bolts are also loosened. It must not be allowed to hang on the brake hose; it must be taken to the side and hung on a wire.
7. To make it more comfortable to work with the stand removed, the nut needs to be removed, but there is no need to unscrew it completely. Then the 3 support nuts are unscrewed.

8. Unscrew the CV joint nut completely and simultaneously remove both the CV joint and the strut.
9. Use the device to compress the spring evenly on both sides.
10. You can easily disconnect the support from the compressed spring. A new support is installed.
11. Assembly is carried out in reverse order.

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.

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.

Variation and checking the condition of the support bearing

Many owners of VAZ 2114 cars often encounter the problem of extraneous knocking in the struts, the main cause of which is the support bearing. If you suspect a fault in the support bearing, you do not need to immediately rush to replace it; first of all, check its condition.

Before assessing the importance of the support bearing in the overall assembly of the car, it is necessary to understand the structure of the suspension. In the assembly of VAZ models, hydraulic struts are used, the main function of which is to smooth out vibrations in the suspension spring during driving, and also to ensure the quality and safety of its operation.

The support bearing is a component of the front suspension shock absorber strut. Its function is to allow smooth movement of the connection between the shock absorber and the car body. If it malfunctions, problems arise with driving the car, and an unpleasant knocking sound occurs in the suspension, especially when driving on a bad road.

Support SS20

Type of support bearing

• With inner built-in ring or outer built-in ring. For installation there is no need to use clamping flanges; in this case, holes are provided for installation.
• The outer ring is detachable.
• The inner ring is detachable.
• The finishing bearing has strong rigidity.

Type of support bearing

The support bearing has a self-explanatory name; it is something like a support for the front shock absorber strut, located in the area of ​​​​the connection with the car body. This arrangement provides for axial loads that the bearing can withstand.

To make an accurate diagnosis of a support bearing, it is necessary to carry out a number of simple manipulations:

• Under the hood of the car, you need to place your palm on the bearing. At this moment, the second person is pumping the car, the appearance of knocking indicates the need for an urgent replacement of the support.
• But, still, it is better to carry out the necessary procedures for removing and subsequently disassembling the bearing.

All VAZ models need to change their support bearings after 40,000 km.

A completely deteriorated bearing, in addition to knocking, disrupts wheel alignment; this factor creates a danger when driving and increases wear on the shock absorber struts. Those drivers who categorically do not want to pay attention to the malfunction of their own car increase the chance of complete bearing failure, which will result in a hole in the hood from the strut. And as a result, financial investments increase significantly. Think about whether this is a way to get away from the problem that has arisen.

Diagnostics

To diagnose the current condition of the support element, you need to perform a couple of simple steps.

1. Open the hood and place your palm on the element, that is, the bearing. In this case, your assistant should rock the car. If a knocking sound is heard, then it should be changed immediately.
2. Disassemble the structure to clearly see that the element is faulty and needs to be replaced. It is important to note that the approximate service life of the support bearing on a VAZ 2114 is 40 thousand kilometers. This is the recommended mileage after which the element must be replaced, regardless of its current condition.

If you do not pay attention in time and do not take appropriate action to eliminate the breakdown, you risk completely destroying the suspension of your car. It is not uncommon for a hole to form in the hood from the pillar. As you understand, such problems entail significant financial losses.

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

Replacement

First of all, we recommend watching a training video about the replacement. This will allow you to broaden your horizons, clearly understand the replacement steps, and also consistently perform a similar procedure, thereby returning the shock absorbers and suspension to their previous functionality.

Replacing the support is performed in the following sequence of your actions.

1. Raise the car using a jack.
2. Unscrew the wheel nuts and remove them.
3. Remove the cover from the nut located on the hub.
4. Loosen the hub fastening.
5. Remove the steering linkage from the rack. To do this you will need a mounting tool and a hammer.
6. Now remove the ball joint and remove the mounting bolts.
7. The next step is to remove the brake caliper. To do this, the fasteners and brake hoses are first disconnected.
8. The stem nut must be loosened. There is no need to completely dismantle it.
9. Be sure to tighten the springs.
10. Unscrew the bearing fasteners. The stand, along with the support and the disk, is removed. You have to replace them with new ones.
11. The unit is being assembled with a new element. The procedure is performed in reverse order.
12. It is advisable to replace the nut with a new one and tighten it properly. Just calculate the force, since the fastening nut is often torn off.

Replacing rear struts on a VAZ 2114 with your own hands in your garage

Well, now I’ll try to describe to you the replacement of the rear suspension.

1. First, we need to get rid of the plastic in the trunk for more convenient dismantling/installation of the rear suspension

2. Remove the plug from the rear glass

3. Using a special wrench (its price is 150 rubles) and a carbon socket wrench, we tear off the nut securing it to the rod.

5. We jack up the car and place it on houses (pyramids)

7. Unscrew the bolt securing the strut to the beam; if the suspension has not been dismantled for a long time, you will have to work hard to remove this bolt.

8. Unscrew the nut securing it to the rod completely.

9. Pull out the stand; if it doesn’t come out, tap it gently with a hammer.

10. I couldn’t pull out the rear strut support; it was stuck there, dead, well, it’s okay; the spring got stuck on me as is.

12. We pump the new shock absorber 5-8 times, raising the rod to the top, holding in the upper position for 5 seconds and lowering the rod to the bottom and also holding for 5 seconds. And we repeat the operation again.

13. We saw off a circle from the bumper, and with the thick side of the bumper we insert it into the casing (the casing and bumper can, in principle, be left as old if they are in good condition).

14. Install a spring, a protective casing with a bumper and a rubber seal on the shock absorber.

15. Insert and install the stand back. If the lower mount of the rack does not allow us to properly install the structure, then the jaws into which it is installed can be slightly knocked down with a hammer.

16. Tighten the lower mount of the rack.

17. We take another jack and lift the beam with the stand to the top until the rod in the glass comes out to tighten it. Another option is to simply guide the rod with a wire and gradually lower the car from the jack. but in my opinion it’s better to use another jack.

18. We tighten the upper fastening by installing the rubber seal and washer and tighten everything with a nut on top.

20. We remove the car from the house (pyramid)

21. tighten the upper rack mount as much as you can.

22. Putting the plastic back together.

Well, that's basically all. Regarding the suspension, I’ll say that I really liked it, although they said that it was hard, well, it can’t be compared with my leaking struts))) it goes softly smoothly, 160 km in the car you don’t feel it at all, when before at 90 everything was shaking)))

HOW TO CHECK THE OPERATION OF A SUPPORT BEARING

The main reason why owners decide to carry out such repairs is an extraneous knock when driving over even minor uneven road surfaces. When such discomfort occurs, replacing the support bearing is not always the best solution. First you need to check its performance, because the problem may lie in other parts of the shock absorber.

Checking the functionality of this suspension element is quite simple:

1. open the hood;
2. place your palm on the support;
3. a partner rocks the car from side to side;
4. If a characteristic cracking or knocking sound is heard under the palm, the bearing must be replaced.

It is important to know that failure or wear of the support bearing results in accelerated wear of the struts and a violation of the wheel alignment settings.

Supports for rear shock absorbers VAZ 2114

But is it worth believing?

in any case, until you deliver it yourself you won’t know whether it’s worth it or not. I liked it, I noticed the difference with the stock bagels, well, it’s easier for me in this regard, because the sneakers cost 15 and the slightest added softness in the suspension is already felt.

So there is no need to take that topic as truth.

But no, last year I also placed Asomi in front of the defensive midfielders.

The struts are stock, they don't knock, they don't leak, we checked them.

further discussion disappears

You can’t even tell me about the non-flowing and non-knocking SAAZ, you’ve already heard and seen it, so the fact that you put Asomi on the obvious g@$but and didn’t sense the difference, excuse me, these are your problems, I think you understand what everything is for me, for some reason it didn’t even occur to me to put such a thought on the g @$but the stock of the Acomi strut, because it’s clear that you won’t get anything and won’t notice anything, since the support doesn’t live on its own, but works and gives the declared characteristics of a completely taken and working suspension.

Threat, I installed the Acomi supports in front on a new suspension (not Saaz struts) after a week of riding on the same suspension, BUT with the stock supports, I immediately noticed the difference with the Acomi. ease of rotation of the steering wheel, softness.

NAUexx

Here you see what’s the matter: initially the Saaz racks don’t work as they should be, this is a normal rack, plus from the factory the Saaz is soft to the point of disgrace, so it’s practically useless to catch the declared characteristics of the Acomi supports on these racks, and if we consider the option with a mileage Saaz, then here’s
my Saaz scribe, according to all yours according to the signs, it seemed to work, and they had only 15 miles on them, but when they were removed, I was horrified for some reason, the rods were shaking with dips, and in the rack it was so crazy that the balls were dangling, although it also looked dry and worked when pumping the car/ held.

ESSENTIAL TOOL

A high-quality replacement of support bearings on a VAZ 2114 with your own hands requires a minimum set of tools to perform these tasks:

• Standard set of open-end and ring wrenches size 12-24;
• Steering rod puller;
• Standard auto jack;
• Coupler for shock absorber springs;
• A “19” wrench is used to remove the strut rod nut.

Unscrewing the nut

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.

Few people know, but bearings are used not only in rotating parts. This article will focus on the support bearing. You will learn what it is, how to diagnose a malfunction and how to replace a VAZ support bearing?

HOW TO CHOOSE A SUPPORT BEARING FOR A VAZ 2114 CAR

The modern automotive industry offers a huge selection of this type of spare parts. Almost every car shop will provide any support bearings for the VAZ 2114, of various quality and price categories.

For this car model, the following types of bearings are most often used:

• support bearing with non-separable rings. Its advantage is the presence of installation holes that do not require clamping flanges;
• Design with removable inner ring. It is used for increased rotation accuracy of the outer ring;
• A completely dismountable system is used for increased rotational accuracy of the inner ring.

Based on the design and the availability of financial resources, the VAZ 2114 front strut support bearing is selected, which will be most suitable in your particular case. Do not save money, since low-quality products are unlikely to last more than 10 thousand kilometers and the procedure must be done all over again. The approximate price of journal bearings ranges from $10 to $80, depending on the manufacturer and design. By saving on the purchase, you risk damaging the shock absorber struts, and then repairs will cost several times more.

Recommendations for checking and extending the service life of supports

If replacement is required

To easily and quickly dismantle a worn out faulty unit, you need to prepare a special rack wrench. It is assembled from 2 tubes of different diameters, obtaining a lever of the appropriate length.

Periodic inspection

Regular inspection and timely maintenance are a guarantee of increasing the service life of spare parts. Check the unit after 10-12 thousand kilometers, especially since this is not difficult to do.

Timely lubrication

Regardless of the car’s mileage, at least once a year (preferably twice, in spring and autumn), it is necessary to lubricate the support with silicone grease. Carry out the work with the protective cover removed.

Accurate vehicle control

Driving your car carefully, without sudden acceleration or jerking, as well as driving on good roads, is the best way to protect parts from premature wear.

Modernization and strengthening

To strengthen the supports, spacers are used to increase ground clearance and auto-buffers, which absorb the load. They also make a spacer between the posts.

The best manufacturers

OPs are produced by different companies. The optimal solution is to install original parts. Purchasing spare parts made in China is risky and there is a high risk of defects. Users of numerous forums note the best bearing manufacturers:

HOW THE REPLACEMENT IS MADE

It’s immediately worth noting that many modifications of these cars have the same suspension. For example, replacing the support bearing of a VAZ 2115, VAZ 2114 and VAZ 2109 is absolutely identical.

Let's proceed directly to the repair itself. There are several ways to carry out the work:

1. removing the entire rack, with steering arms and other parts attached to it. In this case, the wheel tilt settings are saved, and you do not have to perform the wheel alignment again;
2. you can disconnect the strut from the steering cam and then dismantle the remaining parts.

FIRST METHOD

1. We dismantle the hub cap and unlock the CV joint
2. We unscrew the CV joint until it is completely loose, while the brake pedal should be in a clamped state.
3. Jack up the car and unscrew the wheel.
4. Unscrew and unscrew the tip nut and press out the pin.
5. Next, you need to dismantle the ball and free the brake hose from the shock absorber.
6. Loosen the strut nut and unscrew the three support fixation nuts. Then the CV joint is removed and the strut is dismantled.
7. Next, the spring is tightened, which is required before changing the support bearing on the VAZ 2114.
8. After this, we put everything in place until the car is completely assembled.

SECOND METHOD

1. We jack up the car and remove the wheel.
2. Then loosen the hub mounting clamp and remove the steering tip.
3. We dismantle the ball and remove the brake caliper.
4. Next, loosen the strut nut and tighten the spring.
5. We change the support bearing and put everything back together.

After completing the work, it is advisable to replace the strut mounting nut with a new one.

Auto repair school - Do-it-yourself car repair

Jul 18, 2022 VAZ 2108, VAZ 2109, VAZ 2110, VAZ 1117 Kalina, VAZ 2170 Priora by admin

The upper supports of the front shock absorber struts on VAZ-2108, VAZ-2109, VAZ-21099, VAZ-2110, VAZ-2115 cars are quite reliable and durable. You don't have to change them often, but you still have to. And the reason for replacing the upper supports is usually one of the two reasons given below (in some cases, both reasons can come together;)). The first reason is tears and cracks in the rubber part of the support. As a rule, this occurs due to aging of the rubber. Of course, at first glance there is nothing terrible, but a support that is in this condition will be much worse at suppressing noise and impacts while the car is moving. The second, more noticeable, one might even say annoying reason, is the failure of the upper support bearing. This happens much more often than the breakage of a rubber element and adds just as much more worry. Since a support with a broken bearing knocks loudly, even on small uneven roads, and this greatly gets on the driver’s nerves. And as a result, there is a desire or need to replace the upper supports. This is what we will talk about next...

I would like to reassure you right away that it is possible, even necessary, to replace the upper support of the front struts on VAZ-2108, VAZ-2109, VAZ-21099, VAZ-2110, VAZ-2115 And this work should not cause you much difficulty. The main thing is to prepare thoroughly. That is, not only read this article, but also buy (rent) the necessary tools. First and foremost, you will need spring ties . It wouldn't be possible without them. Look, photo 1.

Second, a special key that allows you to hold the strut rod while unscrewing the nut. If the stock strut has already been rebuilt and the liner has been replaced, a hex wrench will be needed, usually a 6 in size, . Photo 2. Of course, you can try to do without this key and use available means. But, nevertheless, it is better to buy it, its cost is low, and unscrewing the nut of the strut rod with it is much easier and more comfortable.

And third, this is a universal steering rod puller (photo 3). This item is optional; you can get by with a pry bar and a hammer to unpress the steering tip pin. However, I can say that the finger is sometimes so tight that you have to knock on the rotary lever hard and for a long time! Which will not have a very good effect on his condition. It's up to you to decide whether to buy or not.

And there is not much more about the tools that you will need to replace the upper support on VAZ-2108, VAZ-2109, VAZ-21099, VAZ-2110, VAZ-2115 cars : socket or ring wrenches 13, 17 and 19, pliers.

Spare parts . We choose from the assortment provided by SEVI (Russia). The supports, and one might say all the products, from this manufacturer are of very high quality and have long earned the trust of motorists.

Let's move on to the description of the process of replacing the upper support of the front strut on VAZ-2108, VAZ-2109, VAZ-21099, VAZ-2110, VAZ-2115:

1. Loosen the wheel bolts. We use a special wrench to lower the shock-absorbing strut rod nut; it cannot be completely unscrewed now. In my case, the liner had already been changed, so I had to use a hexagon and a 10-mm socket wrench, and the wrench for the stock shock absorber, let’s call it “oval,” rested quietly next to it (photo 4). We jack up the car and remove the wheel.

2. Unscrew and unscrew the steering tip nut. Use a puller to unpress the tip pin (photo 5). Disconnect the brake hose from the strut.

3. Then you can proceed according to three options. I will describe all three, and you will choose the one that suits you.

Option number one, the easiest way, but with a slight drawback: we remove the strut separately from the steering knuckle. To do this, unscrew the two rack mounting bolts, one of which is adjustable. But, before unscrewing, we put several marks on the adjusting bolt and the stand. This trick will allow you not to disturb the camber angle of the front wheel, although not one hundred percent, but the deviation will be minimal. Photos 6 and 7 show where it is better to put marks.

The second method is more labor-intensive, but allows you not to touch the camber bolts. Using this method, you will have to remove the strut assembly with the steering knuckle. To do this, unscrew the front hub nut, the front brake caliper and unscrew the ball joint (the steps are the same as when replacing the front wheel bearing). In principle, nothing complicated, you will just have to tinker more and stock up on a strong 30mm head with a wrench and a long pipe (without this it is very difficult to unscrew the front bearing nut).

The third method is generally not for everyone. Suitable for people who don’t want (or are afraid) to disassemble and unwind a lot. But they rely on the strength and dexterity of their hands. This method allows you to replace the upper support without removing the strut from the vehicle. To do this, it is enough to install the couplers on the springs (the lower end of the coupler behind the post, the upper end behind the coil of the spring). Compress the spring. Unscrew the three nuts securing the upper support and lower the strut as low as possible (as far as the suspension arms will allow). He will manage to get the support and install it just as cleverly. Ehhh…. Sorry, but I don’t have photographs of this cunning and dashing method. Because I don't work that way. I consider it both difficult and, most importantly, dangerous. Ties installed this way can fly off and cause injury, and if they come off when the support is unscrewed, it will be, well, the lid! As I said above, this method is not for everyone. I suggest staying with the first option.

4. Place reference marks, unscrew and remove the bolts, and disconnect the strut from the steering knuckle.

5. Unscrew the three nuts securing the upper support (photo 8).

6. Remove the stand and fix it in a vice. We install the spring ties opposite each other and compress the spring until it dangles freely between the upper and lower cups (photo 9).

7. Finally unscrew the shock absorber rod nut, remove the support and install a new one (photo 10).

We carry out the assembly in the reverse order, set the marks, not forgetting to lubricate the camber bolts (for example, with nigrol), since they like to stick, and this is very bad.

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.
