Here's my busted Differential pictures...

[Mike E]

For those of you that are interested in what a differential looks like when it fails...

[mancilg]

looks like someone shot it

[DRTYFN]

It's like a little toy differential.

[rkcrawl]

No internal shots? Bummer.

[HummerNewbie]

That would explain the leaking fluids

[Mike E]

No internal. If i was there i would open it up but I had to rely on the service guy to take the pics.

It might have looked like this

[deserth3]

I'd be interested to see the inside.

This question may have been answered in the past but.....

Is the front diff on the H3 an AAM 725? 185mm (7.28") ring gear.

Is the rear an AAM 800 or AAM 860? 205mm (8.07")or 220mm (8.66")ring gear.

I believe it is the 860

Couldn't they patch the hole? Yes, that is one destroyed axle.
GM may have requested it be returned un-opened for inspection; I would if it was my part.

I know, thats why I was curious, to see if it was the same issue with multiple teeth broken off. Sound like in this case one of the tooth chips probably got bound beteen the pinion and a good tooth on the ring gear causing a boom with enough force to send it out through the housing.

I hate for people to be experiencing this and really hope its a problem thats been identified and fixed already. If not, there is gonna be a lot of these from people who wheel them.

some gold bond for bebe's teeth and some chewing gum for mike's hole hell those are both easy to fix on the trail

[usetosellhummer]

That's bad but in Durango at a Hummer event I was helping with tech support when we saw a guy in an H2 over rev and raise the front a foot in the air. She came back down spinning and the front diff cracked open from the center like an egg. We had to flatbed it in and they actually covered it at the Gm trailer at no charge to the dude.

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.

GM should cover this under any circumstances, not just at a Hummer Happening. So far, I believe all have been covered under warranty at the dealers.

Yes they should. Hopefully we won't hear the "THATS OFF-ROAD DAMAGE" bs that came up with the H2s.

[f5fstop]

Component failure is one thing; however, I can see if the case, trans or engine are dragged and pans ripped open not being covered.
