heres a vid of a blown front end

True, the spotters on a dealer sponsored event shouldn't have let the guy do what he did. However, the diff is a piece of crap and this should not have happened. It wouldn't have happened on an H2, JK or other so why does the H3's blow up so darn easy?

My wife's H3 doesn't see much offroad as we use the H2 for that. However, if we did take it offroad under more severe conditions, I'd upgrade to the Alpha cast iron case and aftermarket gears with better hardenging

Yes the aluminum diff is crap. It is undersized for the size and torque of the H3 and should have had a cast iron housing from the start. The housing issue has been addressed with the Alpha and hopefully (if rumors are to be believed) the next Alpha will have a bigger diff.

But this issue is not isolated to the H3's. In fact H2's had issues with their housings cracking in the early years. It was a defect rather than a design flaw, but they still broke. And unless you're referring to the JK Rubicon, you'll break diffs and axles on a JK. The Dana 30 and 35c are not exactly bulletproof. And you can even blow up a 44 if you try hard enough. If you play, you pay. Eventually you'll break something.

Done.

Sewie, any plans on swapping on the gears for aftermarket? Some 4.88s with 35s sound really nice....Hehe

Can't get 4.88's for that housing. Plus, you'd be making the ring gear even weaker. Maybe down the road I'd change them out for something stronger. But as long as the truck is still under warranty, I won't be changing them.

Many other owners of 4x4 have inadequate parts and weak designed links. The H3 is promoted as a better choice for offroad. Pilot errors are the exception to the rules....
Lesson learned. Dont spin your wheels

it is amazing that H3 can get through trails (such as this Fordyce creek) where even "off-road only" specials can easily break down...
