After removing the upper control arm assembly, you should inspect the control arm bushings for cracks and tears. If they're damaged or worn, you should take the control arm to an automotive machine shop to have new bushings installed.

Remove the cotter pin from the upper balljoint stud and loosen the stud nut slightly. Place a floor jack under the lower control arm and raise it slightly. Tap the steering knuckle near the upper balljoint stud with a hammer to loosen it. Use a balljoint stud separator if needed (note that this may damage the balljoint boot). Remove the nut from the upper balljoint stud and the upper control arm pivot shaft attaching bolts. Remove the upper control arm and pivot shaft as an assembly.
