    Check outer constant-velocity joint 

  9. Clean all parts.
  10. Check ball raceways of joint hub, ball cage, constant velocity joint hub, and balls for signs of wear (arrows).

    IMPORTANT

    If these parts exhibit major signs wear, the outer constant-velocity joint must be replaced. Smooth areas and running marks caused by the balls are not a reason to replace the outer constant-velocity joint.

  11. Assemble in the reverse order.
