Solution

1. Preparation

Gather tools and parts required for the replacement.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Use a 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 Joint

Tools Required: Socket set, ball joint separator, hammer.
Remove the nuts securing the ball joint to the control arm and steering knuckle.
Use a ball joint separator to disconnect the ball joint from the steering knuckle.
Remove the ball joint from the control arm by unbolting it.

4. Install the New Ball Joint

Tools Required: Torque wrench, new ball joint.
Position the new ball joint into the control arm and secure it with bolts.
