On the control arm, the replacement bushings are molded together one piece and install as one piece. I usually do a little wire brush action before trying to push the old ones out. If you haven't already, look into the Moog problem solver ones installed for max caster. Ball joint nut. I was talking of using the bfh to separate the spindle from the BJ instead of wedging a pickle fork in there and tearing up the boot. A couple raps and the spindle/knuckle usually falls free from the stud.
