Bearing hub rear wheel It is intended to ensure its free rotation on the pin (axis of the hub), 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-replacement rear hub bearing, 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.Connect 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 the opposite side, fasten 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. 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 is a dynamometer key, make a tightening by 186.3-225.6 nm. Do not forget to lean your nuts.

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 easy 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 the previous repair. However, this can be easily avoided if before self-replacement Rear wheel hub bearings in advance to study the sequence of work and emphasize attention 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. None outsided sounds And the backlash will not be.

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.

The axis or semi-axis (call as you want) the rear hub on VAZ 2110-2112 cars is changing in exceptional cases. This is done either if the thread is damaged when it is no longer restored, or after the accident as a result of curvature, which is also extremely rare. If you suddenly have to face a similar problem, then the procedure for replacing the semi-axis will be discussed below.

First consider the list of tool required for repair:

Head end 17 mm
Extension
Patty handle
Gorotok
A hammer
Screwdriver shock cross
Penetrating lubricant

How to remove the rear hub axis on the VAZ 2110, 2111 and 2112

It is worth noting the fact that before proceeding to this procedure, you must perform some preparatory work, such as the:

Removing brake pads (read in the article -)

After that, we will not interfere with us and you can proceed directly to the work itself. First of all, it is better to apply penetrating lubricant to the axis fastening bolts. And then try to disrupt them with a powerful turning, as shown in the photo below:

When the bolts were broken, you can finally unscrew them with a ratchet to do it faster and more convenient:

When they coped with it, try to disconnect the axis along with the brake casing from the back of the beam. Typically, the axis sticks to such an extent that it is not necessary to do without a hammer. In this case, on the reverse side, we apply penetrating lubrication to the place of the junction of the casing and beam.

After that, screw down a little nut on the thread of the axis and slowly tapping the hammer on it, as clearly shown in the photo below:

Usually after a pair of blows, the casing with the axis bounces off the beam. Now you will need a cross power screwdriver to unscrew two bolts from the reverse side:

And now you can neatly knock the axis from the brake casing, hitting the hammer on it:

And the final result of the work done is shown in the photo below:

Installation passes in reverse sequence and difficulties should not occur. As for the price of this part, it can vary from 400 to 600 rubles per piece.

It is assumed that the hub bearings a passenger car Very reliable, and for complete wear, they must pass at least 100 thousand km. But taking into account the fact that our roads are not distinguished by high quality, these bearings have to change every 50 thousand km, or even more often. On how to independently replace the rear hub bearing on the VAZ 2109 car, we will tell in this article.

Purpose and location

Rear Wheel Hub Bearing

Hub Bearing - the most important element The chassis of the car, on which the safety of passengers and the driver depends. If at least one of the wheel bearings fail, the car can become uncontrollable, since one of the wheels will no longer rotate normally. In VAZ 2109 cars, radial ball bearing bearings are used. This bearing is painted on the rear semi-axle, you can get to it, only removing the wheel.

The wheel bearing indicates the number 4

Causes of the rear hub bearing breakage

The bearing has failed, fully generating its resource (after which the so-called metal fatigue arose).
The bearing collapsed due to the sand and dirt entering it, which began to act as an abrasive material, which led to partial or complete abrasion of the bearing parts.
One of the rings of the bearing split due to a strong impact (which occurs when the wheel at high speed falls into a deep pothole on the road).
Nut on the hub is tightened weakly. This leads to the occurrence of a backlash, which gradually destroys the elements of the bearing.

Signs of the Wheel Bearing Fault

When moving, one of the rear wheels publishes a characteristic hum, which with increasing speed goes into how.
A tangible backlash appears on the rear wheel (which can be easily discovered, subdomains the wheel and navigating his hands from herself to himself).
The subdomain rear wheel, manually promoted, rotates with the characteristic hum, which can sometimes be accompanied by a ring of balls rolling in a broken bearing (and the wheel with a good bearing is almost silent).

Important moments

The hub nut on the VAZ 2109 is spinning very much, and in addition, it is often covered with rust. It may take a huge effort to stronger it from the scene. In such a situation, the WD-40 liquid can help. If there is no such fluid at hand, the nut can be abundantly pouring oil and wait 10 minutes.
Not every car owner at hand has a remnant for hub bearings. In this case, to remove the bearing, you can use the hammer and cutting of the steel pipe of the suitable diameter (about 4.5 cm). The main thing is not to damage the pipe the inner surface of the hub. If after the extension there will remain scratches and potholes, the new bearing will quickly fail.
When reverse the hub assembly, special attention should be paid to tighten the hub nut. If it is tightened weakly, the backlash will arise, which will lead to the wear of the bearing. Therefore, with an end head to 30, it is necessary to use the longest gate so that the force when tightening the hub nut is maximum.

Replacing the hub bearings - the procedure with which every new one owner will face early or later. The only question is whether he will be ready for it. If the driver prefers to repair his car on his own, it makes sense to purchase a removal for hubs and bearings in the store. This simple tool will greatly facilitate the work, and will also save the car owner of the mass of time and nerves.

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.

Time standards for replacing the hub, according to those. For VAZ 2109, are 27 minutes when removed wheel. 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 loud 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, which 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 ( outside diameter), 30 mm (inner diameter), 37 mm (width), catalog number 6256706Е1С17;
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.
