Use a lug wrench to remove the lug nuts from the wheel.
Take off the wheel to expose the suspension components.

4. Remove the Ball Joint

Locate the ball joint and remove any retaining clips if applicable.
Use a socket set to remove the bolts securing the ball joint to the control arm.
If necessary, use a pry bar to carefully separate the ball joint from the steering knuckle.
