Outer Constant Velocity Joint

Outer Constant Velocity Joint

In order to replace the grease in case of strong contamination or if the journal surface of the bearings must be checked for wear and damage, the CV joint must be disassembled.

Disassembling

- Mark the position of ball hub to the ball cage and to the housing before disassembling, using a scribe or grindstone.





- Swing the ball hub and ball cage.

- Remove ball bearings in sequence.

- Turn the cage, until two rectangular windows - arrow - contact the CV joint body.





- Lift out the cage with hub.

- Swing the hub segment with the smaller pins into the rectangular window on the cage.





- Remove the hub out from the cage.

Checking

6 ball bearings for each CV joint belong to a tolerance group. Check the stub axle, hub, cage and ball bearings for small depressions (pitting buildup) and chafing. Excessive circumferential backlash in the CV 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

- Install the cage with hub into the joint body.

• Cage must be installed laterally correct.

- Press in opposing ball bearings in sequence, during this, previous position of ball hub to ball cage and to joint body must be reestablished.

- Press the grease into the CV joint body. Refer to => [ Grease Quantity and Type ] Drive Axle Assembly Overview.
