No car node is subjected to such a load as chassis. From here and a large number of faults. This example is the bearing of the rear wheel hub. According to the plan and calculations of the designers, it must maintain at least 100,000 km. Run. But domestic roads and improper exploitation make their own adjustments. Very often the bearing fails, without listening and half of the resource.
In this case, it is impossible to pull with replacement. The point is not that the faulty bearing will cause an even more serious malfunction. IN this case We are talking about security. No need to think that such complex repairs can only be done in the car service. Replace rear wheel bearing replacement can be performed independently.
Consider how to check the bearing of the rear wheel hub. Unlike many others, this malfunction can be localized with almost 100% accuracy. And for example, it is not only experienced, but also beginner motorists, if you know characteristic signs. The main ones are:
- Foreign noise when moving the car. It is often mistakenly confused with "how" the box, but in this case the sound does not disappear even when moving to neutral.
- Unpleasant sound especially to distinguish rear seat, from the faulty wheel;
- There is an explicit slowness to the defective side, and in particularly severe cases, clips are heard;
- Heating the wheel while driving.
All these are indirect symptoms, having heard that the car enthusiast should be alerted and conduct a more detailed check. To do this, you need to use the jack, to accomplish an allegedly defective wheel. Now you need to promote it well.

We are looking for the most passable crossover - 10 applicants. Smoke here.
Gul hears - bad, but not yet deadly. Holding the wheel with your hands on top and bottom, it is necessary to shift it vertically. If there is a backlash - the bearing on the landfill.
What does this happen? Surprisingly, only a third of the bearings "dies" from the natural wear of metal parts. The remaining two-thirds falls for the following reasons:
- Manufacturing defects;
- Heavy operating conditions. For example, a permanent ride for passing roads at high speed;
- Lack of timely service. As a rule, lack of lubrication and falling on the bearing of dust and dirt;
In addition, there is another reason - incorrect installation during previous repairs. However, this can be easily avoided if the rear wheel hub bearing is in advance to study the sequence of work and focus on some details.
Rear wheel bearing replacement with their own hands
Any repair of the chassis of the car cannot be called simple. Not because it requires special education and special skills. The complexity is primarily lies in the complexity of the repair. Removing some details requires decent effort and great patience.
We must be in advance to this ready. The car with a semi-disconnected rear hub in service is no longer eating. If the determination does not disappear - first of all, you need to stock up tool.
Tools and accessories
To change the rear wheel hub bearing with your own hands:
- Jack and suitable wooden support;
- The end key is usually 30 and a suitable piece of pipe, as an amplifier for a turning;
- Key to 12, for the guide disk;
- Cylinder key;
- Round rings for removing stop rings;
- A hammer;
- Chisel;
- Universal puller. You can do without it, but for this you need a certain experience. Therefore it is better to buy it, it is suitable for the bearing of the front hub.
- Mount.
- Well, of course, the new bearing. It is not necessary to get it before time from the package to prevent dirt from entering.
How to change the rear bearing hub on the VAZ 2110: a sequence of actions
First you need to rip the wheel bolts, and raise the car by jack.
ATTENTION, in no case, it is impossible to carry out work on the car installed on one jack, it is necessary to additionally use the wooden stand of suitable sizes.
This is due to the greater effort, which will have to be applied in the process. The car on the jack will be very unstable. Further procedure Next:
- Bolts are unscrewed, and the wheel is removed;
- Now you can remove the boot hubs.
- Remuned guides wheel disks. Sometimes it is not easy to do it, they "zakuat" in aluminum. The main thing here is not to break the face, so do not rush;
- Next, the brake drums are removed. It all depends on how long ago they were not filmed. Sometimes they are dismantled "by hand", and sometimes it is necessary to knock with a hammer, through a tree, on the reverse side. There is another way. Guides are screwed into special holes. It should be borne in mind that the pins cannot be removed discs, it will lead to the destruction of aluminum thread. You can only spin them to a small stretch, then try to dry the disk through the tree. Should help.
- Out of the nutch nut. You will have to try - it is spinning very tight. Therefore, the gorott is enhanced by a segment of a suitable pipe. Care must be taken, the car will swing.
- Removed hub. Of course it is better to use a three-year puller. However, it is not all of all, so you will have to use the "proletarian" way. It is as follows. The wheel is installed on the hub and twisted with bolts, but not to the end, and so that there are several centimeters a gap between the disk and the hub. Thus, it turns out some kind of return hammer. Several sharp steers of the wheel, the hub usually manages to remove. And this is half the case.
- Round rings inserted into the appropriate holes, retained ring removed.
- The universal puller is issued or simply knocked out the old bearing;
- The axis of the hub is carefully examined. Sometimes it remains the cost of an old bearing. It must be removed. The bearing is removed, you can move to installing a new one. But first you can see the working brake cylinder. If he has ledges, you will have to change to not shoot the drum again.
- The axis and hubs are inspected for damage, purified from dust, dirt and rust and lubricated with lithol type lubrication.
- The new bearing is pulled out of the packaging, its clip is also easily lubricated by planting part;
- With the help of a universal puller, the bearing is installed in place. In the absence of a device, you can fit the bearing with the help of vice. As a mandrel in this case, the cost of the old one is used. It is not recommended to score a hammer bearing, it can lead to its destruction.
- Now you can install a locking ring;
- Carefully, with the help of a mandrel or tube of a suitable diameter, light blows, the hub is placed in place;
- Fixed nut;
- Put on the place of the brake drum, guides are twisted;
- Wheel twisted. Interest for sake, it is worth trying to shake and twist it. There will be no extraneous sounds and backlash.

Outcome
After removing the car from the stands and the jack, you can try it on the go. Enjoying silence and satisfaction from the work done will be provided. And most importantly, now there is confidence in the reliability and safety of your car.
Unfortunately, sometimes our cars break and need to be repaired, it is necessary to change different details, optics, and in some cases I need a bearing replacement rear hubTrue, as statistics shows, this happens quite rarely.
How to recognize malfunctions in the hub?
The fact is that the hub is the most important element Any rotating mechanism, including a car wheel. It is a central part of rotating parts with a hole to possibly the nozzle on the axis or shaft. Thus, its main task is to ensure the rotational movement. In order for the rotation of the axis to be free, the rolling bearings or special plugs will be pressed into the hub hole. In addition, it is thanks to the bearings of the hub, as well as the wheel can rotate.
It is rather necessary to replace the bearing of the hub, it is quite easy, in this case there is a characteristic knock at the back of the bottom of the body, most often, it is enhanced when driving around the uneven road or at the occasion of the pit, as well as hillocks. During the same movement on a relatively level road surface, a buzz may occur. In addition, the brake drum is very hot.
Checking whether the rear wheel hub bearing is needed
First of all, the reason for such a breakdown serve bad uneven roads, especially since in some cases our road covering In general, it is difficult to call dear. The second reason why the bearing may be unusable, is the poor-quality material from which it was manufactured. The rear wheel is not a very complex process, so it can be quite easy to implement and independently at home.
However, before proceeding directly to actions, it is necessary to find out whether it really matters in it. To do this, it is necessary to post the wheel, from which the hum is heard, and, swaying with his hands, check the backlash. If, when carrying out these actions, the backlash will be detected, and the deaf stuffs will arise, it is impossible to slow with the replacement. The bearing raised on the road will cause damage to other sets of the hub system.
The key to quick and high-quality work is the correctly selected tool and high-quality materials, in this case the bearing. Therefore, do not try to save on it, take options only from good manufacturers, because it largely depends on the service life.
Replacing the rear hub bearing - your actions step by step
From the tool you will need a screwdriver, a jack, a balloon key, a lithol, a puller for the nave nut, sometimes chisel and mount. Next, having prepared everything you need, act as follows. We put the car for the first gear, pre-laying under the front wheels "shoes". We raise the car using the jack and dismantle the desired wheel. By revealing the guides of the pins, you need to remove the brake drum, most often it is knocked down. Now the hub nut is unscrewed by a special puller and the hub itself is knocked down with the pin. It must come together with the ring of the bearing, otherwise it must be removed by mounting and chisel.
In order to fit the bearing itself, it is necessary to remove the locking ring with special tongs and knock the metal boot. Next you need to lubricate the landing place and with the help of a special puller to press back new bearings. At the same time, consider that it is extremely not desirable to score. Now back and stop ring. Having hitting the inner ring of the bearing, we put the hub back to the pin. Next, you need to tighten the pin and how best to hurt her sides. The process is almost completed, blocks, brake drum are installed on the previous places, and, of course, the wheel.

conclusions
As can be seen from the article, replace the rear wheel bearing on the VAZ-2114 car is not so hard, as it seems at first glance, but not all motorists are able to cope with this task, so often contact the car service. It is worth noting that special attention It is necessary to pay to the choice of the product, because the service life of the hub itself depends on the quality of the spare part.
The rear wheel hub bearing is designed to provide its free rotation on the pin (hub axis), as well as the uniform distribution of shock loads arising during the movement of the machine. VAZ-2114 cars are usually equipped with rear-wheelband model bearings 256706, having a double-row ballpoint radial-resistant design of a closed type. They are characterized by a high speed of rotation, but not designed for high loads. Some craftsmen in order to increase the carrying capacity of their cars install roller bearings (model 537906). They are in a sense, stronger, although they have a relatively small speed of rotation. Externally, these two types of bearings do not differ practically, as they do not differ in price, and according to the characteristics, although the balls, for some reason, were gained great popularity.
How to determine a faulty hub bearing
The original Bearings of the rear hubs VAZ-214 "go" for a long time, and can withstand up to 70-100 thousand km of run. And even in the case of a malfunction of one of them or two immediately continue to work. This does not mean at all that it is possible to continue to ride obviously defective bearings, but when you find a problem with them, you will always have a chance to reach the station of maintenance or own garage.
The signs of the faulty bearing rear hub include:
- gul, howl, rustling in the area of \u200b\u200bthe appropriate wheel during movement;
- crunch when driving small irregularities;
- heating hub;
- the play of the wheel (detected by loosening the subdomain wheel).
Selection of spare parts
To replace the rear hub bearing, it will take not only the bearing itself, but also a hub nut. At least this requires a machine manufacturer. Going behind the new bearing of the hub in the auto shop or to the market, it will not hurt to be aware of which parts are suitable for your car, and how can manufacturers be trusted.

What will be required of tools and means
For self-substitution Rear hub bearings you will need:
- cylinder key;
- jack;
- head to "30" with the maximum long handle;
- front wheels;
- emphasis for the hyphenation of the jack (strong pencils, bricks or others);
- a hammer;
- round-rolls;
- a beard or a small slotted screwdriver;
- special puller for the hub (if any);
- small mount, chisel, a pair of wooden bars, vice (if there is no puller);
- gas burner (the burner is also suitable);
- wrenches on "10", "12", "13";
- plastic lubricant;
- dry rag;
- assistant (preferably).
Procedure for performing work
1. Automobile put on a horizontally level platform, turn on the first gear.
2. Refix it with the parking brake and front wheels stops.
3. If the caps are installed on the wheels, remove them.
4. Using a screwdriver, remove the nave nut cap of the corresponding wheel.
5. The cap of the cap is self-locking nave nut. In order for the "Split" nut, with the help of a hammer and a beard (screwdriver), align two dents on the side.
6. Delivery head for 30 on the nave nut and try to unscrew it. If it did not work from the first time, process the available part of the thread of the pin with WD-40 liquid or similar. If you have the opportunity to attract the assistant, ask him to sit in the salon and click on the brake pedal to finally immobilize the car. To increase the power of impact on the head, the maximum extend it to handle. To do this, you can use a segment of a suitable diameter tube.
7.Sorvat the nut, do not unscrew it completely.
8. Ball key Unscrew the mounting bolts of the desired wheel.
9.Pripping the body of the car jack with the appropriate side. Unscrew the wheel bolts completely, dismantle the wheel.
10. Used the key to 10 (maybe at 12), unscrew the guides of the drum pins.
11.Turn parking brake. If possible, release the "handler" cable. So it will be easier to remove the drum.
12. Please take off the drum, taking it with both hands, and, loosening, pull on yourself. If it does not work, take the wooden bar and turn it the drum around the circumference. The place where the inner side of the drum finds the hub, treat the WD-40 liquid. Remove the drum.
13.Tube the hub nut completely. Remove the puck located on it.
14.If there is a puller, secure it as shown in the photo and remove the hub.
15. If the puller in the arsenal of your tools is not, taking a small mount. Help its end in the brake shield, and the working part is pond the protruding part of the hub. You can also take the wheel and deploying it to yourself back sidefasten to the hub. Now grab both hands on it and, swaying, pulling him with sharp movements. If this option did not give results, find two long bolts, and screw them into the holes of the hub. For this purpose, the bolts are perfectly suitable, which is attached to the GBC engines VAZ 2108, 09, 14, 15.
16. After the hub from the axis, pay attention to the fact that the bearing was completely starred, or the inner clip was left on the pin. If it remains, carefully run away with a small chisel, hitting her back.
17. Take the roundhead and remove the retaining ring of the bearing with them.
18. Create the hub in the outlook of the vice or between two bars and tear the bearing with a piece of a suitable diameter pipe, another old bearing, or the same head to "30".
19. Clean the bearing, with a dry cloth, clean the seat in the hub, apply plastic lubricant onto its side surfaces.
20. Write the hub with the help of a gas burner. So it will be easier to establish a new bearing.
21. The hub is hot, put it on a wooden bar, install a new bearing over planting Moz, Put on top of it another wooden bar. Hit the hammer along the bar until the bearing is sitting. It is desirable that the blow has accounted for an internal bearing clip (it is much thicker and stronger external).
22. Set the retaining ring of the bearing.
23. Delivering the hub on the axis, and with the help of a wooden bar as a spacer and a hammer, bring it onto the pin.
24.Sign the puck, screw the new nut.
25. Select the wheel in the reverse order.
26.Gayka hubs tighten completely on the wheel already installed and standing on Earth. If there dynamometric KeyMake a tightening by 186.3-225.6 nm. Do not forget to lean your nuts.
For greater clarity, look the thematic video:
The wheel bearing, brake drum and wheels disk, transit movement, braking, car wheel control, ensuring the safety of the driver and passengers. Replacing the VAZ 2109 hub is quite possible with their own hands, if there is all necessary materials and tools.
The time standards for replacing the hub, according to those, for VAZ 2109, are 27 minutes when the wheel is removed. To change the rear hub will help this instruction with a photo.
How to determine the fault of the suspension and hub
A sign of the replacement of the hub on the VAZ 2109 may be a strong noise or knock while driving. But this is an unreliable source, since the causes of the arms of the knock may be somewhat: the planks of the handbrake can also knock, brake pads, Silent blocks rear rates. It's hard to guess.
To say more precisely, you need to take a jack, raise, twist, flaw and check. The hub bearing is usually not knocking, but it can give a buzz and vibration on the body. A knock, and rather strong, it will only require the replacement bearing.
Check the status of the bearing It is easy - the jack raise the necessary direction, turn and tent a wheel if there is a hum - the bearing to replace. If there is a backlash, check the tightening of the hub nut and wheel bolts.
It is not allowed to remove the backlash in the bearings of the hollows of an excessive tightening of nuts. The torque of the fastening of the hub of the front and rear nuts should be: nut bearing bearing rear wheel hub 186,3-225,6 (19-23) N * M (kgf * m), nuttur bearing nut front wheel 225.6-247.2 (23-25.2) N * M (kgf * m).
When replacing the hub bearing, be sure to inspect the hub if the new bearing on it will be installed very easily, then such a hub must be replaced with a newotherwise she will hang out. And despite replacing the bearing, provoke vibration and knock.
In the hubs of the front and rear wheels, ball-row-row bearings with seals are used that do not require replacement of lubrication and adjustment during operation.
When the hubs are expeded, the bearings are destroyed. Therefore, the extensive hubs must be carried out only in cases of increased noise of bearings or a significant increase in the gap in them: more than 0.015 mm - in the front and more than 0.030 - in the rear.
When choosing a hub bearing, it is necessary to know its dimensions:
- bearing size of the rear hub VAZ 2109 - 60 mm (outer diameter), 30 mm (inner diameter), 37 mm (width), catalogue number 6256706E1S17;
- bearing size of the front hub VAZ 2109 - 64 mm (outer diameter), 34 mm (inner diameter), 37 mm (width), catalog number 2108310302001.
The price of the Bearing VAZ 2109 - 600 rubles is relevant for Moscow and the region (spring 2017).
To replace the hub VAZ 2109 it will take such an instrument:
- jack and balloon key;
- the end key is 30 mm and a long tube on it;
- passatii for removing locking rings;
- simple passage or cape key "at 12" (to unscrew the rear brake drum guide brake pins);
- wooden bar and hammer;
- chisel and montage;
- universal puller for extracting hub or reverse hammer;
- new hub on VAZ 2109 with article 21083104014 or 21103104014.
At first, it is necessary to open a chisel or dumplings to open the bin nut of the hub bear.
Then take the head "at 30" ...
... and weaken the nave bearing nut.
Weaken the wheel fastening bolts.
Subdominate the car. Tighten hand brake, turn on the first gear and substitute for the shoe wheels. Remove 4 wheel fastening bolts and remove it.
The key "at 12" we unscrew the two guides.
If the guide is not unscrewed, with the help of the hammer it is necessary to "shake", gently knocking.
Remove the brake drum.
Install the reverse hammer on the hub ...
... and remove the hub.
Take a new hub assembly.
