- Raise the front of the car until the wheel and tire assembly are clear of the ground.
- Support the suspension lower arm until there is no load on the shock absorber.
- Try to rock the wheel top-to-bottom; if any wobble is felt, look for movement between the lower arm and the wheel knuckle.
- If the ball joint appears to be tight, check and adjust the front wheel bearing, then repeat the wobble test.
- If any movement is present, this would probably indicate ball joint wear and the ball joint should be replaced.
- If wear is present, check the tie rod end. The lower arm and stabilizer bar should also be checked.
Removal & Installation
The lower ball joint is an integral component of the lower control arm. If the lower ball joint is defective, the entire lower control arm must be replaced.
