– Turn ball cage -2- until the two rectangular windows -arrow-
rest against joint body.
– Take out cage -2- with hub -3-.
– Swing segment of hub into square cage window.
– Tip hub -1- out of cage -2-.
The 6 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 circumferential backlash in the
joint is noticeable during load change jolts. In this case, the joint
must be renewed. Smoothing and traces of wear of the balls are
no reason to change the joint.
Installing
Install in reverse order of removal, observing the following:
– Pack half of total grease quantity (40 g) into joint body.
– Fit cage with hub into joint body.
– Press in opposing balls one after the other; the original posi‐
tion of the hub relative to the cage and joint body must be
restored.
– Fit new retaining ring into hub.
– Distribute remaining grease in boot.
