OUTER CV JOINT, CHECKING
It is necessary to disassemble the joint whenever replacing the grease or if the ball surfaces show wear or damage.
Disassembling
Mark position of ball hub to ball cage and to housing before disassembling, using electro-writer or grindstone.
Scheme 15
Swing ball hub and ball cage.
Remove balls in sequence.
Turn cage, until two rectangular windows -arrow- contact joint body.
Scheme 16
Lift out cage with hub.
Swing hub segment with smaller pins into rectangular window on cage.
Scheme 17
Fold hub out from cage.
Checking
6 balls for each joint belong 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.
Note. Cage must be installed laterally correct.
Press in opposing balls in sequence, during this, previous position of ball hub to ball cage and to joint body must be established again.
Press the grease into the joint body. Refer to DRIVE AXLE ASSEMBLY OVERVIEW .
