Inner Constant Velocity Joint, Checking

Disassemble joint to replace grease or check for wear and damage.





- Swivel ball hub and ball cage.
- Press out ball cage in direction of arrow.
- Press balls out of cage.

NOTE: Ball hub and joint are paired and must not be interchanged.





- Tilt ball hub out of cage over ball track (arrows).
- Check joint housing, hub, cage and balls for pitting and signs of seizure.

NOTE: Excessive backlash in joint will be noticed as a knock during load changes. In such cases replace joint. Polished areas and ball track marks are not reasons to change joint.

Installing:





- Insert ball hub over both chamfers into ball cage. Hub can be installed in any position. Press balls into cage.
- Insert hub with cage and balls at right angle to joint.





NOTE:
- When inserting ensure wide space -a- on joint housing is aligned with narrow space -b- on hub.
- Chamfer on inner diameter of ball hub (splines) faces larger diameter of joint housing.





- Install ball hub; hub must be swiveled out of cage (arrows) far enough to allow balls to fit in ball tracks.

Constant velocity (CV) joint, checking





- Press cage firmly (arrow) until hub swings fully in position.
CV joint is correctly assembled when ball hub can be moved by hand back and forth over its entire axial range.
