1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Pry bar
- Hammer
Safety Warnings:
- Ensure the vehicle is on a flat surface before lifting.
- Always use jack stands to secure the vehicle.

2. Remove Wheel

Loosen the lug nuts on the wheel.
Lift the vehicle with the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Ball Joint

Use a flashlight to inspect the ball joint for any cracks, wear, or torn boots.
Use the pry bar to apply slight pressure to the ball joint and observe for excessive movement.

4. Replace Ball Joint (if necessary)

Disconnect the ball joint: Remove any retaining bolts or nuts securing the ball joint to the control arm or steering knuckle.
Remove the ball joint: Use a ball joint separator tool or a hammer to carefully tap the ball joint out of its socket.
Install new ball joint: Position the new ball joint into the socket and secure it with the appropriate bolts/nuts. Follow torque specifications provided in the service manual (typically around 35-50 ft-lbs, but check specific manual).
Reattach components: Reinstall any components that were removed during the process, ensuring they are properly torqued.

5. Reassemble Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts in a star pattern to the manufacturer’s specifications.
