Self replacing wheel bearing

In some cases, from the front wheels a characteristic noise is heard, which may indicate that it is necessary to replace the hub bearing. Many motorists immediately spread their hands, they say, how to independently change the bearing of the hub. And sent to a maintenance station. In the case of a new or very expensive car, this may be the most appropriate choice. But if the car is already more than ten years, then the bearing can be completely replaced by own forces.

In order to replace this part yourself, you will need a spacer bearing. It consists of a powerful bolt, three thick washers (the largest of which is with a nut), rings of outer diameter. A large washer with a thread is located on the outside of the ring, and the middle is inside it (as compared to the outer diameter of the bearing, it is somewhat smaller). In the absence of a puller, you can use the tacks and good hammers.

In order not to have to make the alignment, it is necessary to remove the shock absorber with the hub and the pivot. There is nothing complicated in this, but the disintegration is still undisturbed.

Detailed replacement of the wheel bearing:

- the hub nut is unscrewed by a head for 30 and a good collar with a pipe;

- the rod stem nut is lowered under the bonnet;

- the wheel is removed;

- the steering tip is detached from the steering knuckle;

- the brake mechanism is disengaged from the pivot;

- the bolt of fastening to the hub of the brake disc is loosened and removed;

- fastening of the ball bearing is untwisted from the pivoting fist; by pressing the lever, the rack with the rotary fist is removed from the ball bearing (the shock absorber remains hanging on the upper cup, since the nut on the rod of the shock absorber is not completely unscrewed);

- the bolts of the mud guard of the brake disc are loosened, they are removed;

- the shaft of the outer SHRUS is removed from the hub and, holding the rack from below, the nut of the shock absorber rod is unscrewed to the end;

- the shock absorber assembly is assembled with a hub and a swivel fist, the bearing is pressed out from the hub, using the same head for 30 and a two-finger puller (it is possible with the help of mounts and a hammer), the hub, squeezed out of the bearing, while taking half the inner bearing ring ;

- the puller from the pivoting fist extrudes the bearing, in this case the locking rings are removed beforehand;

- the hub is clamped in a vice, with the help of a hammer and a chisel, the remaining inner race of the old bearing is knocked off the hub, a few cuts are made on the casing by a Bulgarian (the inner casing is usually broken from the first blows);

- in some cases, some part of the bearing can remain on the hub, and to get rid of it, you will have to make efforts (but it is necessary to be very careful, since if the hub surface is damaged, it will have to be replaced).

All dismantled and removed, all parts are cleaned of dirt and the replacement of the hub bearing is almost complete, only the assembly remains:

- A circlip is inserted from the inside of the fist;

- the front new hub bearing is pressed into the swivel fist with the help of a puller, the larger the bearing is oriented into the swivel fist, into the lock ring until it stops;
