To install the hub later, 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 wheels with brake discs.
1. Place the rear of the vehicle on jack stands. The rear wheel suspension should be unloaded, and the wheels themselves should hang freely. Place chocks under the front wheels to prevent the car from rolling forward and slipping off the jacks.
2. Remove the wheel to access the desired hub.
3. Use a small chisel to knock off the protective cap from the hub nut. At the same time, turn the hub so that the cap can be knocked off 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, this means that the caliper will have to be removed. After disconnecting the caliper, secure it to the body using wire. Do not leave the caliper suspended by the brake hose.
5. Loosen the rear wheel hub nut using a socket head and a ratchet.
6. Remove hub 1 using the puller mentioned above. The jaws of puller 3 are installed around the circumference of the hub. The pressure rod 2 must rest against the hub axis to avoid damaging the thread. The puller spindle should not enter the hub axle thread (see illustration).
6.6 Remove hub 1 using a puller. The jaws of puller 3 are installed around the circumference of the hub. The pressure rod 2 must rest against the hub axis to avoid damaging the thread. The puller spindle should not enter the hub axle thread
7. Remove the oil seal from the hub axle. To do this, you can use a screwdriver to press the seal. Remember the installation position of the oil seal.
8. Remove the inner bearing ring from the hub axle (see illustration). The jaws of the puller must be positioned to grip the ring by its inner diameter. The illustration shows a drum brake mechanism. On vehicles with disc brakes, removing the inner ring of the wheel bearing is performed identically.
6.8 Remove the inner bearing ring seated on the hub axle using puller 1. The illustration shows a drum brake mechanism. On vehicles with disc brakes, removing the inner ring of the wheel bearing is performed identically
When installing the hub, proceed as follows.

9. Clean the hub axle and install a new hub on the axle. Tap the hub with a rubber or plastic hammer until it seats properly.
10. Press on the hub using puller 2 (see illustration). Instead of a puller, you can use a piece of pipe that is placed on the hub axle. Then, a disc of approximately the same diameter as the hub is placed on the axle to press the pipe and hub. The old nut is screwed onto the axle, which replaces the puller's 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 placed on the hub axle. Then, a disc of approximately the same diameter as the hub is placed on the axle to press the pipe and hub. The old nut is screwed onto the axle and tightened until the hub is completely in place
11. Remove all hardware after installing the hub in place.
12. Screw on the new hub nut, having first lubricated its mating surface and threads, and tighten the nut to a torque of 110 Nm. Then, from this position, tighten the nut by 60° further, without using a torque wrench (see illustrations).

13. Install the new hub nut cap and tap it in place with a plastic hammer. Now you can install the brake drum or disc in place. If the brake disc is being installed, tighten the disc's mounting pin to a torque of 25 Nm and install the caliper, securing it to a torque of 30 Nm. As for the drum-type brake mechanism, the setting pin is tightened with the same torque.
Caution: Make sure the vehicle is securely supported before tightening.
14. Replace the wheel and lower the vehicle.
15. Tighten the wheel nuts to a torque of 100 Nm.
It is recommended that wheel alignment be performed in a workshop. If the rear wheel alignment does not match the nominal values, then it can be assumed that the rear suspension is skewed. The design of the rear suspension is such that the camber and toe angles of the wheels do not change.
