I just replaced my upper and lower ball joints myself. Man was it a bi*ch to change out the lowers. The pins would not come out. Finally I got them out and replaced them. Put everything back together and what a huge alignment issue I have. It looks as if the wheels are about to fall off. I hope I just have to get it aligned to fix that problem. Well...I also fixed the brake problem too. Needed new calipers and had to clean the brake system out. Lots of dirt and crap in the master cylinder and control valves etc. Got that all clean and put it back together and drove it. Still drives great. Now I am going to align it and sell it. This time it should not have any problems for a while. Anyone interested???
