The six balls for each joint belong to a tolerance group. Check
stub axle, hub, cage and balls for small indentations (pitting) and
traces of seizing. Excessive backlash in the joint will cause knock‐
ing or jolts under load change. In this case the joint must be
replaced. Smoothing and traces of wear of the balls are no reason
to change the joint.
Installing
Installation is carried out in reverse order, noting the following:
– Pack half of total grease quantity (40 g) into joint body.

– Fit opposite balls one after another. In doing so, take care to
re-establish the original position of the ball hub relative to the
cage and the joint body.
– Fit new retaining ring into hub.
– Distribute remaining grease in boot.
