Checking 

6 balls for each joint belongs to a tolerance group. Check stub axle, hub, cage and balls for small depressions (pitting build-up) and chafing. Excessive circumferential backlash in joint makes itself noticed via tip-in shock, in such cases joint should be replaced. Flattening and running marks of balls are no reason to replace joint.

Assembling 

• Insert cage with hub into joint body.

• Press in opposing balls in sequence, during this, previous position of ball hub to ball cage and to joint body must be re-established.
• Press grease into joint body → Grease quantity and type  .
