Removal
Carefully remove the hub cap (4) using a plastic or rubber mallet or screwdriver.
Pull the handbrake and loosen the self-locking nut (5) slightly, without unscrewing it completely.
1 - wheel speed sensor (only on cars with ABS);
2 - brake caliper;
3 - brake disc;
4 — hub cap;
5 - self-locking nut;
6 — inner race of outer wheel bearing;
7 — rotor (only on cars with ABS);
8 — rear wheel hub;
A - drum brake;
B - disc brake.
Remove the brake caliper.
After unscrewing the retaining bolt, remove the brake disc (3)

Remove the wheel speed sensors (if any).
Unscrew the nut (5) and remove the outer roller bearing.
Remove the brake drum and wheel hub.
On vehicles with ABS: Remove the wheel hub and rotor.
Installation
Check the O-ring on the rear of the hub/drum. If there is any trace of grease, replace the O-ring.
Make sure that there are no defects on the surface of the bearings and their races.
Check the hub and brake drum for wear and damage.
Insert the hub/brake drum and, if equipped, the rotor.
Fill with bearing grease and insert the outer bearing.
Tighten the new self-locking nut to 150 Nm. At the same time, hold the hub from turning by inserting a tire iron between the studs. Place the wrench horizontally. Tighten the nut in several steps, turning the hub/brake drum in different directions in between to prevent the bearing from seizing.
Check the play of the hub bearings. Required value: 0.2 mm. If the clearance is large, tighten the hub nut to a maximum of 200 Nm until the required clearance value is obtained.
Secure the wheel speed sensor, if equipped.
Check the bearing breakaway moment by attaching one end of the cord to the hub/brake drum studs. Attach a spring balance to the other end of the cord and pull at a 90° angle to the studs until the hub/brake drum begins to rotate. The spring scale readings should not exceed 2.2 kg. If the starting torque is very high, the hub nut should be loosened slightly. If the required values of tightening force, bearing play and breaking torque are achieved simultaneously, replace the hub bearings.
Apply bearing grease to the hub cap and insert it until it stops in the hub.
Install the brake disc or brake drum.
