1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Required tools: Jack, jack stands, lug wrench, socket set, torque wrench, pry bar, and safety goggles.
Safety warning: Always engage the parking brake and use jack stands to secure the vehicle.

2. Remove Wheels

Loosen the lug nuts slightly while the vehicle is still on the ground.
Jack up the vehicle and securely place it on jack stands.
Fully remove the lug nuts and take off the front wheels.

3. Remove Ball Joint

Locate the ball joint on the control arm.
Use a socket set to remove the bolts securing the ball joint to the control arm and steering knuckle.
If applicable, use a ball joint separator tool to detach the ball joint from the steering knuckle.

4. Inspect and Clean

Examine the removed ball joint for any signs of wear, including cracks or excessive play.
Clean the ball joint area with a degreaser to remove any dirt and debris.

5. Install New Ball Joint

Position the new ball joint in the control arm and steering knuckle.
Tighten the bolts to the manufacturer's specified torque settings (refer to vehicle service manual for exact values).
Reattach any cotter pins or clips if applicable.

6. Reassemble

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then fully tighten the lug nuts in a crisscross pattern to ensure even tightening.
