Volkswagen Golf Service & Repair Manual: Checking outer constant velocity joint
| The joint is to be dismantled to renew the grease if it is
heavily soiled, or to check the running surfaces of the balls
for wear and damage. |

| – |
Before dismantling, mark position of ball hub in relation to
ball cage and joint body with an electric scriber or oil stone. |
| – |

|
|
|
| – |
Swing segment of hub into square cage window. |
| The six balls for each joint belong to a tolerance group.
Check stub axle, hub, cage and balls for small indentations
(pitting) and traces of seizing. Excessive circumferential
backlash in the joint is noticeable during load change jolts. In
this case the joint must be renewed. Smoothing and traces of
wear of the balls are no reason to change the joint. |
| Install in reverse order of removal, observing the
following: |
| – |
Pack half of total grease quantity (40 g) into joint body. |
| – |
Fit cage with hub into joint body. |
| – |
Press in opposing balls one after the other; the original
position of the hub relative to the cage and joint body must be
restored. |
| – |
Fit new retaining ring into hub. |
