Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, ball joint separator, torque wrench, grease gun.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Raise the Vehicle

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

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel for better access to the ball joints.

4. Inspect and Replace Ball Joints

Clamping Method: If the ball joint is worn, use a ball joint separator to remove it from the control arm.
Installation of New Ball Joint:
- Align the new ball joint with the control arm.
- Use a press tool to push the new ball joint into place, ensuring it is seated properly.
- Torque the mounting bolts to the manufacturer's specifications (usually around 40-50 lb-ft, check service manual for exact specs).

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically around 80-100 lb-ft).

6. Lubrication

If the ball joint has a grease fitting, use a grease gun to lubricate the new ball joint until grease begins to come out of the boot.
