Checking
-
Check joint piece, ball hub, ball cage and balls for small broken off depressions (pitting build-up) and chafing.
Note: Excessive circumferential backlash in joint makes itself noticed via tip-in shock. Joint must be replaced in such cases. Flattening and
running marks of the balls are no reason to replace the joint.

Insert hub with cage and balls upright into joint piece.
Note: When inserting, make sure that in each case the wide gap -a- at joint piece contacts narrow gap -b- at hub after swinging in.
