Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which ball joint you are inspecting.
Secure the vehicle with jack stands to ensure safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the ball joint.

4. Inspect Ball Joint

Visually check the ball joint for any signs of wear, such as cracked or torn boots.
Use a pry bar to lift the control arm and check for play in the ball joint by feeling for movement.

5. Replace Ball Joint (if necessary)

Remove Old Ball Joint:
- Use a socket set to detach the bolts securing the ball joint to the control arm.
- Employ a ball joint separator tool if necessary to detach the ball joint from the steering knuckle.
Install New Ball Joint:
- Position the new ball joint in the control arm.
- Secure it using the bolts and torque them to the manufacturer's specifications (usually around 50-70 ft-lbs, verify with the service manual).

6. Reassemble

Reattach the wheel and securely fasten the lug nuts in a crisscross pattern for even tightening.
Lower the vehicle back to the ground.

7. Final Check

Double-check that all components are securely fastened and that there are no tools left in the engine bay.
