Not to thread jack, but I have the same thing around 80-85 mph. It's only on the passenger front and now has worn the outside of the tire. I'm thinking control arm bushing, but want some opinions or similar experiances. Any help would be greatly appreciated by the both of us I'm sure! Should I just rebuild everything on that side? How tough it it for someone fairly competant with tools? Thanks ya'll, I always come here for help and info when working on my X!
