Jack up the rear axle and support the axle on 

stands.

between the driven wheels.

lamp should not light up and the "rigid" 

connection between the driven wheels

Inspect the bearings for damage at the 

following points:

-

the roller bearing race,

-

the bearing cage,

-

the raceways of the inner and outer 

race.

If damage is found, the entire bearing (inner 

race/bearing cage and outer race) should be 

replaced.

2.

If the outer race of the bearing is loose in the 

hub or has turned in the hub, the hub should 

be replaced.

3.

Check the axle journal screw thread, the 

bearing surfaces of the inner bearing races 

and the running surface of the seal for 

damage.

Check the wheel speed sensor ring for 

damage. Replace the ring at even the 

slightest trace of damage.

checked for the maximum admissible axial 

end play. See "Technical data".
