Our 2002 chev tahoe experienced a crack in the rear differential cast iron case. It has been replaced twice, and is ready for a third time. Looking for solution to repeated cast iron case cracking. It occurs in the same place each time, about 1: 00 just about the cover. We are ready for the 4th differential and would like to make this repair the last-suggestions?
