Well what inspired me is my second set of diffs finally went to the point they needed rebuilding, so on Saturday i sat down and 3 hours, 6 cigarettes, and 4 blisters later my dffas where so smooth a freind of mine who used to race with Adam Drake and Josh Cyrul commented they where the smoothest he had ever felt!!!!!! Next to Joshes of coarse!!!LOL Then I told him I learned how to properly rebuild diffs from a article Josh had written!!!!!!!!
