Ball Guide, Slipper retainer, and Hold-Down Pins
The ball guide should be free of nicks and scratches, and should not be excessively scored. Examine for
discoloration that may indicate excessive heat or lack of lubrication. The slipper retainer should be flat,
and slippers should fit in the retainer with minimal side play. Place the hold-down pins on a flat surface
and roll them to make sure they are straight. Discard and replace any damaged parts.
