Audi A4: Inner CV Joint, Checking
It is necessary to disassemble the joint whenever replacing the grease or if the ball surfaces show wear or damage.
Disassembling
Note
Ball hub and joint are paired and should be identified before removal. Do not interchange ball race allocation.
- Tilt the ball hub and ball cage.
- Remove the joint in the direction of the -arrow-.
- Remove the balls from the cage.
- Flip out ball hub from ball cage via the ball race -arrows-.
- Check the joint, ball hub, ball cage and balls for small broken off depressions (pitting) and chafing.
Note
Excessive backlash in joint will be noticed as a knock during load changes. Joint must be replaced in such cases. Flattening and running marks on the balls are no reason to replace the joint.
Assembling
- Insert the ball hub into the ball cage via two chamfers. The installation position is arbitrary. Press balls into cage.
- Insert hub with cage and balls upright into joint piece.
- When inserting, make sure that in each case the wide gap -a- at joint piece contacts narrow gap -b- at hub after swinging in.
- Chamfer on inner diameter of wheel hub (splines) must face toward drive axle.
- Swing in ball hub, to do so swing out hub far enough from cage -arrows- so that the balls have the distance of the races.
- Swing in hub with balls by pressing forcefully onto cage -arrow-.
