H3,
The reason I asked if it was off-road suspension versus non-off-road suspension is that the gear sets are different between the two packages. The actual rear end housing might be identical, but if the gear ratios are different, they are manufactured on different machines.
If one line is not cutting the gears correctly, and causes premature wear, which in-turn causes pieces of metal to float in the axle; tearing up the gears, then it might show as different packages.

Evidently, from information here, it appears to be about 50/50 between off-road and non-off-road suspension packages. Therefore it sounds like one of the common gears, shafts or splines in the rear end is causing the problem.

You guys in the plant may have had a quality spill from a supplier, and not even known, since this type of problem does not show up until the vehicle has some miles. Hopefully, the supplier caught the problem early and corrected the problem.

However, in my opinion (which counts for nothing), if there are that many failures with this small of a population of owners, then this would worry me. Let's face it, there are a heck of a lot more owners of H3s out there that never surf this site, then there are those who do surf this site.

Have to admit, I keep listening to my rear end (the Hummer's rear end) while driving. So far, the vehicle has been great. Well, except for a door seal I had to fit back onto the push pin.
