Here's my busted Differential pictures...

yep, that is one of the weak areas in the H2 also. I have see a few H2 open up like a cracked egg. Usually they are spinning and suddenly catch traction when they crack from the sudden shock load to the axle. I don't believe these H3s were spinning or broke traction at the time they broke the gears.

Those look like cast aluminum bearing caps in the picture. The caps will let things move when the strain becomes high enough. Definitely some room for improvement.

GM should cover things if they happen @ a sponsored event or Hummer Happening. Those are supposed to be controlled situations. Dealers are required to do two off-road events per year and damage to the truck there should be warrantied. I have seen one of our local dealers give a demo to customer and flatbed a broken rig back to the shop for warranty repairs more than once at Hummer Happenings. That is what customer satisfaction is all about and that customer will remember next time they are looking for a new Hummer.
