Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Lift the Vehicle

Using a jack, lift the front of the vehicle and secure it with jack stands.
Remove the front wheels to gain access to the suspension components.

3. Inspect the Ball Joints

Visual Inspection: Look for any cracks or tears in the rubber boot and grease leakage.
Play Check: Grasp the tire at the 12 o'clock and 6 o'clock positions and try to rock the wheel. Excessive play indicates worn ball joints.

4. Replace Ball Joints (if necessary)

Remove Old Ball Joint:
1. Remove any retaining clips or bolts securing the ball joint.
2. Use a ball joint separator tool to disconnect it from the control arm.
Install New Ball Joint:
1. Position the new ball joint and secure it with the retaining clips or bolts.
2. Torque the bolts to the manufacturer's specified torque value (typically around 50-70 ft-lbs, check specific model specs).

5. Reassemble and Lower the Vehicle

Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 75-100 ft-lbs).
Lower the vehicle safely off the jack stands.
