Ball joints are a pain on a 123 or a 126 if you don't have the magic tool. I've done both cars without it (used generic tool instead). Really don't want to do that again too soon. Oh, and I managed to NOT replace one of the inner control arm bushings on the 123 (left and right sides were done at different times in different ways). Now I have to go back and replace the blasted one on the lower arm so I can get the car to align. All this on a car I'll probably scrap! Arrrgghhh!
