Note: For cars with light metal rims, the wheels must be removed when adjusting the play. For cars with steel rims, installation is performed with the wheels still on.
Raise the vehicle with steel wheels so that the wheel to be adjusted rotates freely.
For vehicles with light metal rims, remove the wheels.
Crush the wheel cap.
Before checking the bearing play, you need to make sure that the rotation is smooth and quiet by rotating the wheel. If you hear noise when rotating the wheel or the rotation is uneven, you should remove the hub, clean it and check if the bearing is damaged. Otherwise, replace the bearing.

Checking the play
The play is checked using a screwdriver. The bearing play is set correctly if the protective washer barely moves when pressed with a finger using a screwdriver.
Caution: In this case, under no circumstances should you apply rotational or squeezing force with a screwdriver to the hub.
If the cotter pin cannot be inserted, tighten the castle nut until the groove and hole for the cotter pin align.
Check if the protective washer moves.
If it does not move, then you need to loosen the crown nut instead of tightening it until the groove and the hole for the cotter pin match.
Secure the hub axle nut with a cotter pin.
Install the hub cap and wheel cover.
On cars with light metal rims, install the wheels, tighten the bolts crosswise with a force of 90 Nm. Lower the car.
