Caution:
Refer to Vehicle Lifting and Jacking Caution.
- The joint is loose.
- The ball seal is cut.
- The ball stud is disconnected from the knuckle.
- The ball stud is loose at the knuckle.

- Ball Stud Inspection
-
Make sure to check the tightness of the ball stud in the knuckle boss during each inspection of the ball joint. One way to inspect the ball stud for wear is to shake the wheel and feel for movement of the stud end or the nut at the steering knuckle.
Another way to inspect the ball stud for wear is to check the fastener torque at the nut. A loose nut can indicate a stressed stud or a hole in the knuckle boss.
Worn or damaged ball joints and knuckles must be replaced.
