Re: Another Rear Differential
What 'symptoms' did you feel in the H3 while driving to make you take it to the dealer? Wow .. a lot was replaced! Was it covered by warranty? Glad they took care of it!

Re: Another Rear Differential
Man you must have one heck of a big Hummer. That looks live the ring out of at least an 18 wheeler!

Yes, all warranty work. Loud noise coming from the rear end and vibrations felt in the gas pedal were the main symptoms. At first I thought I might have had the "rubbing compound" issue, but as the tech observed, the gears were just way out of alignment. I'm not sure whether the misalignment was from the factory or whether an off-road trip caused flex in the housing, or whether something completely different was the cause.

Re: Another Rear Differential
ABS sensors not reading will set a code and turn on the idiot light as well as display a message in the DIC.

Yeah, I would have expected to see something...but that was not the case.

Re: Another Rear Differential
Yes, take it back. If filled properly, it cannot be overfilled, since you fill to the bottom of the fill hole. Adding more fluid only pours out of the fill hole. If it was only on the diff, I would say they were just extremely messy, but since it appears to be all under the rear of the vehicle, it appears fluid is being forced out and spraying on the bottom of the vehicle.
However, not impossible to put a seal into the housing incorrectly. They did something wrong.
Is this the same dealer who rebuilt it the last time? And the same dealer who said the EBTCM did not pick up the rear wheels speed sensors being out of adjustment? Mmmmmm

Looks like you're getting a new rear axle this time. Take another look at your third picture.

Re: Another Rear Differential
I see that now, but what about photo 4. WTF is that in the fuel tank? Sure looks strange to me.

Re: Another Rear Differential
Picture 4 looks worse than it is -- I think some leaves got stuck in the drain hold to the fuel skid and then got coated with diff fluid / muck.
I'm not sure what I'm looking at in Picture 3:
Is that a plug that came "un-plugged", or is that a hole that shouldn't be there? How might this have happened?
