What tools do you need?

The most important thing is the key for 30. The collar should be as long as possible. The torque of the nut on the hub is very large. However, the spanner is suitable if it has small bends. When removing and installing, you will need a punch or a small chisel. It is desirable to acquire a universal puller for bearings, as well as for the wheel hub. You need to have at least some pliers, but better, of course, a puller for the retaining rings. It is also necessary to have in your arsenal a key for 12 or 8, depending on which pin is in your hub. With this key, it is necessary to unscrew the guide pin, with which the drum is fixed. But the latching nut of the handle is turned by means of a key on 13. Sometimes a head for 14 is necessary. And the most important tool in this procedure is a good hammer. Without a new bearing complete with snap rings and nuts you can not do. However, the replacement of the front wheel bearing of the VAZ 2109 is similarly carried out.

Preparation for repair

It is much more convenient to carry out all repairs on the inspection pit. Of course, in the case of its absence, you can install the entire rear of the car on the supports. To do this, you need to securely fix the car body, setting it on a flat surface. The front wheels must be fitted with stops, and the first gear is engaged. Before starting the work, it is necessary to release the nut, which was tightened by the hand lever.

Please note that when working without a pit, you must completely hang out the side of the car on which maintenance is being carried out. Under it to establish a reliable support, then with grief in half to reach the place of installation of a latch nut. Works performed to replace the hub bearing, similar to all versions of front-wheel drive vehicles. On the wheel hub there is a protective cap that you have to remove. After that, arm yourself with a chisel and a hammer, straighten the bent edge on the nut. The procedure is fairly simple, so it does not require special explanations. In the same way, the front hub VAZ 2109 is replaced. The differences are minor.

Unscrewing the nut

Now loosen the rear wheel hub nut. Take the key for 30, if necessary, increase the length of the wrist. The longer the lever, the easier it will be to unscrew this nut. And slowly tightens the tightening. Extend the handle of the key can be using a metal pipe. In order not to rotate the wheel, it is necessary that the assistant hold the brake pedal in the depressed state. However, if the car is installed on all four wheels, there is no need to hold the brake. Stops under the front wheels can keep the car. This procedure is necessary if the rear hub of the VAZ 2109 is being replaced.

Removing the wheel

When you get rid of the nut, you need to remove the wheel. To do this, first loosen the bolts, which made the fastening. Then lift the side of the car on the jack and install it on the support. Only after this it is necessary to completely unscrew all the bolts and remove the wheel. Then using a key on 12, and on some models of the car - on 8 or 10, it is necessary to unscrew the guide pins with which the brake drum is fixed. It is advisable to tap the hammer carefully before starting this action. Please note that it is best to use the spanner keys to unscrew these pins. In the same way, the hub of the VAZ 2109 is being replaced. With your own hands, all the work can be done very quickly.

Removing the drum

With the brake drum, there should not be any problems, since the parking brake is already loose. A little pull on the drum and make circular motions in one and the other direction. Do not try to knock down the drum with a conventional hammer, if suddenly it is badly removed. It is best to tap it around the circle with a rubber mallet. Only after this, you can completely unscrew the nut to which the hub is attached. Remove it, as well as the washer that is under it. After this, the hub of the rear wheel can be removed.

Removing the hub

In the event that you do not have a special puller, you need to take the wheel that you just dismantled, turn it over so that the back side looks at you. Secure it to the hub with at least two bolts. Do not tighten them, just wrap them in 5-7 turns. Now apply strong pressure on yourself. Just be careful not to accidentally fall on your back. For several approaches, the hub must go off its axis. Then it is necessary to remove the circlip from the inside of the bearing. The hub of the front wheel of the VAZ 2109 is disassembled in the same way. It is only necessary to replace it if there are mechanical damages.

Bearing Removal

This is done with special forceps, but you can use thin screwdrivers. The inner ring on the bearing must be removed using a special two-lantern puller. But if there is no such thing, put a chisel in the back of this ring and carefully apply several hammers with a few strokes. When this ring starts to move, it is necessary to completely dismantle it with the help of a mounting blade. Please note that in the presence of minor damages, which necessarily appear after working with the chisel, it is necessary to clean them using a measuring file. Now you can remove the bearing itself.

It is desirable to do all the work with a puller, it takes just a few seconds. But if it is not, then you will have to use a piece of pipe, the diameter of which is the same as that of the bearings. You will also need a larger hammer, because it's almost impossible to do this job. The blows must be sharp and strong. How much you will suffer with this bearing is unknown. Under such a scheme, replacing the bearing of the rear hub VAZ 2109 can be stretched for a long time. It is possible that all the work on the molding will take from 30 minutes to an hour.

Bearing installation

With the installation of a new bearing, things are much simpler - you can do it with a puller or with a vice. But the easiest way is to hammer with a hammer. The main thing in this business is to install a spacer made of wood. When the new bearing is almost equal to the hub, take the clip of the old one in order to apply it as a spacer. After installing a new bearing, you will need to install a retaining ring. As in the case of disassembly, it is necessary to use either a puller or a thin screwdriver. But the replacement of the rear wheel bearing of the VAZ 2109 is not yet complete. The roller needs to be put in place.

Installing the hub

Now it is necessary to install the hub with the new bearing on the shaft. To do this, it takes a lot of effort, pushing it must be done manually. If it does not move, then with a hammer with a spacer, apply a few sharp strokes. Just put them on the outer ring carefully. Then put the washer on and put the nut on the wheel hub axle. When the nut is tightened, the hub sits completely on its axis.

Install the wheel drum in the reverse order. At the very end, it is necessary to tighten the nut on the hub. The moment should be at least 19 kgf / m. But if you do not have a torque wrench, you'll have to remember how much effort was applied to the nut when unscrewing. Same exact and tighten it. This completes the replacement of the rear hub bearing VAZ 2109, the comfort has increased, extraneous sounds have disappeared.
