I went back and looked at your thread. LICelsior is correct in that I did change out my differential (gotta love a good junkyard), actually it was a year ago. I did not change any bushings. Whatever was there, got reused. I did not do the replacement by myself, as I had a mechanic help me to do so. I do not know of any place to get the bushings specifically for the differential itself. What is the car doing?? How do you know that you need bushings in the diff?
