For the subsequent installation of the hub, you will need a piece of pipe and a disk of a sufficiently large diameter.
Removing the hub is the same for both wheels with brake drums and brake discs.
1. Put the rear of the car on jack stands. The rear wheel suspension must be unloaded, and the wheels themselves must sag freely. Place chocks under the front wheels to prevent the vehicle from rolling forward and slipping off the gantry.
2. Remove the wheel to access the desired hub.
3. Knock off the protective cap from the hub nut with a small chisel. At the same time, turn the hub so that the cap can be knocked down gradually along its circumference. When removing the cap, be careful not to damage the cap itself.
4. Remove the brake drum or brake disc. If a brake disc is installed, then this means that you will have to remove the caliper. Having disconnected a support, fix it on a body by means of a wire. Do not leave the caliper hanging on the brake hose.
5. Loosen the rear wheel hub nut using a replacement socket and wrench.
6. Remove a nave 1 by means of a puller mentioned above. Puller cams 3 are installed around the circumference of the hub. The pressure rod 2 must rest against the axis of the hub so as not to damage the thread. The puller spindle must not enter the threads of the hub axle (see illustration).
6.6 Remove hub 1 using a puller. Puller cams 3 are installed around the circumference of the hub. The pressure rod 2 must rest against the axis of the hub so as not to damage the thread. The puller spindle must not enter the threads of the hub axle
7. Remove the oil seal from the hub axle. To do this, you can use a screwdriver, wringing out the gland with it. Note the mounting position of the gland.
8. Remove the bearing inner race sitting on the hub axle (see illustration). The jaws of the puller must be set so as to grab the ring by its inner diameter. The illustration shows a drum brake. On vehicles with disc brakes, the removal of the wheel bearing inner race is identical.
6.8 Remove the bearing inner ring sitting on the hub axle with a puller 1. The illustration shows a drum brake mechanism. On vehicles with disc brakes, removal of the wheel bearing inner race is identical
When installing the hub, proceed as follows.
9. Clean the hub axle and install a new hub on the axle. Stuff the hub with a rubber or plastic hammer so that it sits well.
10. Press on the hub using puller 2 (see illustration). Instead of a puller, you can use a piece of pipe that is put on the hub axle. Then, in order to tighten the pipe and the hub, a disk of approximately the same diameter as the hub is put on the axle. The old nut is screwed onto the axle, which replaces the puller pressure spindle. The nut is tightened until the hub is completely in place.
6.10 Press on hub 1 using puller 2. Instead of a puller, you can use a piece of pipe that is put on the hub axle. Then, in order to tighten the pipe and the hub, a disk of approximately the same diameter as the hub is put on the axle. The old nut is screwed onto the axle, which is tightened until the hub is completely in place
11. Remove all attachments after the hub is in place.
12. Screw on a new hub nut, having previously lubricated its contact surface and thread, and tighten the nut with a torque of 110 Nm. Then tighten the nut from this position by 60°without using a torque wrench (see illustrations).

13. Install a new cap of the hub nut and fill it with a plastic hammer. Now you can install the brake drum or disc in place. If a brake disc is installed, it is necessary to tighten the disc mounting pin with a torque of 25 Nm and install the caliper, securing it with a torque of 30 Nm. As for the drum type brake, the setting pin is tightened with the same torque.
Attention! Make sure the vehicle is secure before tightening.
14. Replace the wheel and lower the vehicle.
15. Tighten the wheel nuts to 100 Nm.
Wheel alignment is recommended to be carried out in a workshop. If the alignment of the rear wheels does not match the nominal values, then it can be assumed that there is a misalignment of the rear suspension. The design of the rear suspension is such that the camber and toe angles do not change.
