Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, pry bar, grease gun.
Ensure the vehicle is parked on a level surface, and the ignition is off.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure it with jack stands to ensure stability.
Place wheel chocks behind the rear tires to prevent movement.

3. Remove the Wheel

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

4. Inspect Ball Joints

Visually check the ball joints for any signs of wear, such as cracked rubber boots or excessive grease.
Use a pry bar to apply upward pressure on the control arm to check for play in the ball joint.

5. Replace Worn Ball Joints (if necessary)

Removal:
- Disconnect the sway bar link if applicable.
- Remove the cotter pin and nut securing the ball joint to the steering knuckle.
- Use a ball joint separator tool to detach the ball joint from the knuckle.
Installation:
- Position the new ball joint and secure it to the steering knuckle with the appropriate nut.
- Reinstall the cotter pin after tightening the nut to the manufacturer’s specifications (typically 30-50 lb-ft).
- Reattach the sway bar link if it was disconnected.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 100 lb-ft).
Make sure everything is secure and then lower the vehicle completely.
