After realizing that my diff bushings were shot I also found the cover was leaking and I think the clutches are finished as well. As I was working under the car I rotated the drivers side rear tire forward and the passenger side didn’t move so now I’m thinking as long as I have it out I might as well do it all right ? My question is how hard is it to replace the clutch packs with the carbon kit that American Muscle sells?I’ve done a lot of work on cars over the years but never rebuilt a diff. Need a little guidance on this
