Inner CV Joint, Checking

Inner CV Joint, Checking

Removing

In order to replace grease in case of contamination or if the journal surfaces and ball bearings must be checked for wear and damage, the CV joint must be disassembled.

- Swing the ball hub and ball cage out.





- Press out the ball joint housing in - direction of arrow -.

- Press the ball bearings out of the cage.

• The ball hub and joint piece are paired. Do not interchange.

- Flip out the ball hub from the ball cage via the running path of the ball - arrows -.





- Check the joint piece, ball hub, ball cage and ball bearings for small broken off depressions (pitting buildup) and chafing.

Excessive circumferential backlash in the joint makes itself noticed via tip in shock. Joint must be replaced in such cases. Flattening and running marks on the ball bearings are no reason to replace the CV joint.

Installing

- Insert the ball hub into the ball cage via the two chamfers. The installation position is random. Press the ball bearings into cage.





There are 2 different distances between the ball tracks of the ball hub, a large and a small one.

- Insert the hub with the cage and balls upright into the joint piece, a smaller space - b - must face toward the open side of the joint piece when doing this.





- Also observe the chamfer on the inner diameter of the ball hub which must be visible after swinging in.

- Swing in the ball hub; to do so, swing out the hub far enough out of the cage - arrows - (as depicted in illustration).





- Swing in the hub with the ball bearings by pressing forcefully onto the cage - arrow -.





- CV joint, checking for function

CV joint is properly assembled, if the ball hub can be slid back and forth by hand over the whole compensation length.
