I replaced all the control arm bushings in my 70 challenger while restoring it. Had it on the road about a year now and about 6 months ago, got tired of hearing the passenger side upper control arm squeak, so I replaced both bushings (again, used the offset one in the front position for increased positive caster). Solved the problem immediately, although when removed, you could not make the bushing squeak or slip in the arm, looked perfectly fine. Now the driver side is squeaking!!! What's up with that?
