Check constant velocity joint
8 | Check ball raceways of joint ring (37c), joint hub (37d), ball retainer (37f) and balls for pitting and signs of wear (arrows). |
If the outer constant velocity joint is defective, the rear axle shaft (37a) must be replaced. |
If these parts exhibit major wear, the entire rear axle shaft (37a) must be replaced. Smooth areas and running marks caused by the balls are no reason to replace the rear axle shaft (37a). |

Assembling CV joint
9 | Insert rear axle shaft (37a) with joint hub (37d) and ball retainer (37f) into joint ring (37c) and align so that balls can be inserted. |
Before inserting the joint hub (37d), pack half the grease provided in the repair kit into the joint ring (37c). |
10 | Position ball retainer (37f) onto joint hub (37d). |
Note the applied markings. If markings were not made, the ball retainer (37f) has to be positioned on the joint hub (37d) such that a wide bar of the joint hub (37d) is always opposite a narrow bar of the joint ring (37c). |
11 | Insert balls one after the other. |
