Little late, but a bit ago I disassembled one of my transmissions to check what parts I needed for a rebuild. I inspected the differential and other parts to see what needed to be replaced. I put the differential with the output shaft on a tray under the car in the garage. About 6 months later (without moving it at all). Still without moving it, I looked at it and it had an obvious crack in the casing of the differential. This was over winter so it appears it was weak and then from the expand and contraction, cause sometimes I would run a heater in the garage, it developed a crack. Car was supposed to have about 300 whp at that time.
