Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, ball joint separator
Safety Warnings: Ensure the vehicle is on a flat surface, and use jack stands for safety.

2. Remove Wheel

Loosen the lug nuts on the affected wheel.
Use a jack to lift the vehicle and secure with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Ball Joint

Remove any components obstructing access to the ball joint (e.g., brake caliper, rotor).
Unbolt the ball joint from the control arm using the appropriate socket.
Use a ball joint separator to detach the ball joint from the steering knuckle.

4. Inspect and Replace

Inspect the old ball joint for wear and compare it to the new part.
Place the new ball joint into the steering knuckle and secure it to the control arm.
Torque the bolts to the manufacturer’s specifications (typically around 50-60 ft-lbs, but check service manual).

5. Reassemble Components

Reinstall any components removed in Step 3.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specification (usually 76-83 ft-lbs).
