1 - Wheel speed sensor (only on vehicles 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 vehicles with ABS)
8 - Rear wheel hub
Removal
Carefully knock off the hub cap "4" with a plastic or rubber hammer.
Set the handbrake and loosen the self-locking nut "5" without unscrewing it.
Remove the brake caliper, see p. 18.5.
Remove the brake disc "3" by unscrewing the retaining bolt.
If present, remove the wheel speed sensor.
9 Loosen nut "5" and remove outer roller bearing "6". Do not drop the bearing.
9 Remove the brake drum/wheel hub.
On vehicles with ABS: Remove the wheel hub and rotor.
Caution: Handle the rotor with care. The rotor teeth must not be scratched or damaged, as this may adversely affect the functioning of the ABS.
Installation
Check the condition of the sealing ring on the rear of the hub/drum. If traces of grease are visible, replace the ring.
Make sure that there are no chipped areas or changes in the color of the surface of the bearings and their races.
Check the hub/brake drum for wear or damage.
Insert the hub/brake drum and, if applicable, the rotor. Possibly tap the hub/brake drum in with a plastic hammer.
Fill with bearing grease and insert the outer bearing.
Tighten the new self-locking nut to 150 Nm (100 Nm on cars manufactured from 1.84 to 8.88). Clamp a tire iron between the studs to prevent the hub from turning (do not damage the threads). High tightening force! Place the wrench horizontally to prevent the car from sliding off the supports when tightening. Tighten the nut in several steps, turning the hub/brake drum in different directions in between to prevent the bearing from seizing.
Note: The old nut can be tested for re-installation. To do this, screw the nut onto the wheel stub by 2 and 3 mm. Loosen the nut with a torque wrench. If the loosening force exceeds 5.5 Nm, the nut can be re-installed.
Check the play of the hub bearings. The required value is 0.2 mm. If the play is large, tighten the hub nut to a maximum of 200 Nm (on cars manufactured from 1.84 to 8.88 - 150 Nm) until the required play value is achieved.
If available, secure the wheel speed sensor.
Check the bearing breakaway torque. To do this, attach a cord to the hub/brake drum studs as shown in the figure. 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 starts to rotate. The spring scale (spring balance) readings should not exceed 2.2 kg (on vehicles manufactured from 1.84 to 8.88, 1.7 kg, with the spring balance attached directly to the lower stud). If the breakaway torque is too high, loosen the hub nut slightly. If the required tightening force (150 Nm - 200 Nm), bearing play and breakaway torque values cannot be achieved simultaneously, replace the hub bearings.

Fill the hub cap with bearing grease and press it in until it stops.
Install the brake disc.
Install the brake caliper, see paragraph 18.5.
