Ball Joint



Ball Joint Wear Limit

Look for any horizontal movement of the knuckle relative to the control arm.
The control arm assembly must be replaced if the following conditions exist:

* The joint is loose.
* The ball seal is cut.
* The ball stud is loose at the knuckle.

Replace worn or damaged ball joints and knuckles.
