I replaced my rear ball joints on the weekend. That was interesting. I have never seen a car with a rear suspention quite like my 88 delta. Sure made a difference in the handling though, I didnt realise how bad the back end swayed and how much bump noise it made until I replaced them.
Thank god for hydraulic presses... I would have never gotten them out without it. I removed the whole A-frame and pressed the joint out and the new one back in... Tense moments when you watch the a-frame flexing in the press! All is well in the end
