  11. Loosen the upper control arm ball stud in the steering knuckle using a ball joint stud removal tool. Remove the nut from the ball stud and raise the upper arm to clear the steering knuckle. It may be necessary to remove the brake caliper and wire it to the frame to gain clearance. Do not allow the caliper to hang by the brake hose.
