Solution

1. Preparation

Gather tools such as a jack, jack stands, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure it with jack stands for safety.

3. Remove the Wheel

Using a socket set, remove the lug nuts and take off the front wheel to access the ball joints.

4. Inspect and Replace the Ball Joint

Inspect: Examine the ball joint for damage or excessive play.
Remove:
- Disconnect the ball joint from the control arm and steering knuckle using the appropriate socket and wrench.
- If necessary, use a ball joint separator tool to assist with removal.
Install:
- Position the new ball joint into the control arm and secure it with bolts.
- Torque the bolts to the manufacturer’s specifications (typically around 45-65 ft-lbs, check service manual).

5. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (usually 80-100 ft-lbs).
