- Raise and safely support the vehicles on jackstands. Allow the suspension
to hang free.
- Grasp the tire at the top and the bottom and move the top of the tire in
and out.
- Observe for any horizontal movement of the steering knuckle relative to
the front lower control arm. If any movement is detected, replace the ball

- If the ball stud is disconnected from the steering knuckle and any looseness
is detected, or if the ball stud can be twisted in its socket using finger
pressure, replace the ball joint.
