Outer CV Joint, Checking

Outer CV Joint, Checking

In order to replace the grease in case of contamination or if the journal surface of the ball bearings must be checked for wear and damage the Constant Velocity (CV) joint must be disassembled.

Removing

- Mark the position of ball hub to the ball cage and to the housing before disassembling, using a scribe or grindstone.





- Swing the ball hub and cage out.

- Remove the ball bearings in sequence.

- Turn the cage, until the two rectangular windows - arrow - contact the joint body.





- Lift out the cage and hub.

- Swing the segment of the hub into the rectangular window of the cage.





- Remove the hub out from cage.

The 6 ball bearings for each joint belong to a tolerance group. Check the stub axle, hub, cage and balls for small depressions (pitting buildup) and chafing. Excessive circumferential backlash in the joint makes itself noticed via tip in shock, in such cases the CV joint should be replaced. Flattening and running marks on the ball bearings are no reason to replace the CV joint.

Installing

- Press half of the total grease amount (40 grams) into the CV joint body.

- Insert the cage and hub into the CV joint body.

- Press in the opposing ball bearings in sequence, during this, the previous position of the ball hub to cage and to the CV joint body must be reestablished.

- Install a new circlip into the hub.

- Distribute the remaining grease in the cover.

- 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.
