Was swapping out my shocks this weekend and upon raising the rear lower control arm, I messed up the right rear axle carrier (knuckle) bushing. The control arm cut into it and now I need to replace it. I went to Lexus and a mechanic and both said the bushing is not sold separately and that I will need to buy a new carrier. Can someone please help, there seem to be posts in the GS forums, but none for the IS 350.
