Well, I changed out the left control arm, the rear bushing fell out when I got it loose... The right control arm seems to be a popular part, as it is on back order indefinitely, so I changed the ball joint only. What a PITA!!!! I'd much rather swap the whole control arm, went way smoother. The ball joint pressed out ok, after I had to take everything loose (tie rod, cv shaft... ) in order to get enough room to get the ball joint press in place. The Moog replacement presses in from the top, while the factory part pressed in from the bottom. It has a snap ring to keep it retained. It got a little cockeyed and wouldn't go straight, so I had to work it a bit to get it in, but did finally get it all the way in. After the ball joints, I discover the rear tires are tipping in at the top, looks like bad bushings there, the front struts are leaking, and the inner tie rods are now loose, about 111000 miles on this car and doing more work to it than the 95 Neon I picked up recently... seems the Neon has a better suspension design too.
