Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a floor jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Remove the Old Ball Joints

For Press-Fit Ball Joints:
- Remove the cotter pin and castle nut from the ball joint.
- Use a ball joint separator tool to disconnect the ball joint from the control arm.
- Press out the old ball joint using a ball joint press.
For Bolt-On Ball Joints:
- Remove the retaining bolts and disconnect the ball joint from the control arm.

4. Install New Ball Joints

Clean the mounting area of the control arm.
Insert the new ball joint into the control arm and secure it with retaining bolts or press it in using a ball joint press.
Reattach the ball joint to the steering knuckle and secure with a new castle nut and cotter pin.

5. Reassemble and Lower Vehicle

Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).
Carefully lower the vehicle from the jack stands and remove the jack.
