Well, I think I finally got my rear clunking situation figured out. After replacing the diff, the rear upper shock mounts and the rear subframe mounts, it seems to be a lot smoother and quieter back there. But it was a pain in the butt. Now my question is, is it possible to rebuild my old diff myself? I know it is not recommended but I love a good challenge. The old one is a 4,10 and the new one is a 2,72 I believe ( I have forgotten the exact number-oops!) Anyway, I don't know where I can find the parts and what actually gets replaced. Any help would be great!
