Remove the two bolts that secure the brake caliper to the steering knuckle. Hang the caliper using a wire hanger to prevent damage to the brake line. Remove the brake rotor.

Step 5: Remove the Lower Ball Joint Nut

Use a socket wrench to remove the nut that secures the lower ball joint to the steering knuckle.

Step 6: Separate the Ball Joint from the Knuckle

Use a hammer and a ball joint separator tool to separate the ball joint from the steering knuckle.
