Neo and Bebe's situation is very curious and makes me wonder if the slowness of GM to offer more power is associated with something along these lines or not.
There's one picture where it's obvious the pinion spun some teeth off the ring gear. It seems the same occured in all three instances on both trucks and that maybe even the I-5 is offering too much torque for this diff setup and the weight of the H3.
I would suspect if you tied 10 H3s to anchors and slowly applied the torque on a surface with good traction, several of them would spin out the ring gears if there was some weight transfer. This without the usual culprits of bouncing, over-spinning, etc that is usually associated with this kind of breakage.
