I'd recommend getting new thrust arms instead of just replacing the bushings. This is because the ball socket at the other end is usually slightly worn as well. You have to dismount the entire arm anyhow, unless you have one of the $200 screw tools that BMW shops have, and take the arm to a machine shop who has a pretty strong press to get the old bushing out. By the time you go through that whole drill, I've found that its just as economical and much better fix to replace the whole arm, thus getting a new ball joint at the same time. This is no more than a 100K mile replacement anyhow, and the ball joint is worn just as much over that period. BAS and Eurasian can supply you with an aftermarket assembly with the 750IL heavier bushing in it as their recommended replacement. Bob H>
