Volkswagen Golf Service & Repair Manual: Checking inner 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. |
 Note
| The ball hub and joint body are paired. Mark position in
relation to each other with a waterproof felt-tip pen prior to
removal. |
|
|
|
| – |
Swing ball hub and ball cage. |
| – |
Press out joint body in direction of arrow. |
| – |
Press balls out of cage. |
|
|
|
| – |
Tip ball hub out of ball cage via ball track
-arrows-. |
| – |
Check joint body, ball hub, ball cage and balls for pitting
and traces of seizing. |
Note
| 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 renew the joint. |
|
|
|
| Install in reverse order of removal, observing the
following: |
| – |
Insert hub into cage via the two chamfers. The hub can be
installed in any position. Press balls into cage. |
| – |
Insert hub with cage and balls at a right angle to joint
body. |
|
|
|
| When inserting, ensure that the wide spacing
-a- on the joint body is aligned
with the narrow spacing -b- on the
hub after it is swung in. |
| Chamfer on internal diameter of ball hub (splines) must face
large diameter of joint body. |
| – |
Also take note of chamfer on interior diameter of ball hub.
It must be visible after swivelling in. |
|
|
|
| – |
Swivel in ball hub, at the same time the hub must be
swivelled out of the cage -arrows-
far enough to allow the balls to fit into the ball tracks. |
|
|
|
| – |
Swivel in hub with balls by applying firm pressure to cage
-arrow-. |
| Checking function of constant velocity joint: |
| The constant velocity joint is correctly assembled if the
ball hub can be moved by hand backwards and forwards over its
entire range of axial movement. |
|
|
|
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.
