- Remove any retaining clips or bolts securing the ball joint to the lower control arm.
Installing New Ball Joint:
- Position the new ball joint in the lower control arm and secure it with the retaining clips or bolts.
- Reattach the ball joint to the steering knuckle.
- Torque all bolts to manufacturer specifications (refer to the service manual for exact torque values).

5. Reassemble and Lower Vehicle

Reattach the wheel and tighten the lug nuts in a crisscross pattern to the specified torque.
Carefully lower the vehicle back to the ground.
