Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, ball joint separator tool, grease gun.
Raise the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding.

2. Remove the Wheel

Loosen the lug nuts while the vehicle is still on the ground.
Raise the vehicle and remove the lug nuts completely.
Remove the wheel from the hub.

Locate the ball joint assembly connected to the control arm.
Use a ball joint separator tool to disconnect the ball joint from the control arm.
Remove the retaining bolts or nuts securing the ball joint to the steering knuckle.
Carefully take out the ball joint from its housing.

4. Install the New Ball Joint

Place the new ball joint into the steering knuckle and align it with the mounting holes.
Secure the ball joint with the retaining bolts or nuts. Torque them to the manufacturer's specifications (usually specified in the service manual).
Reattach the ball joint to the control arm using the separator tool if necessary.

5. Reassemble the Wheel

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications.

6. Final Inspection

Inspect all connections and ensure everything is reassembled correctly.
Recheck the torque on the ball joint and lug nuts.
