Re: Third Diff's a Charm
 

Tell me, I blew my first this past weekend:crying: build date may 06 wonder if I had the "new beefier version":confused:

Re: Third Diff's a Charm
 

Just got back from the Dealership.

Went for a spin with the Shop Foreman....he said whatever it is , it is not good.

I still think it's the front ring gear, he opened the door while we were moving, and MAN was it loud. Could be the rear ring gear or the T-case.

I'll side with f5 that it's not likely the t-case.

I'll know more later today!:(

Re: Third Diff's a Charm
 

Man, with all these problems, now I have to worry about mine being an early-built, even though I don't drive it much anymore.

Re: Third Diff's a Charm
 

has anyone blown one in a base model yet ???????????? you maybe safe TGL ;)

Re: Third Diff's a Charm
 

What about other upcoming models? :confused:

Re: Third Diff's a Charm
 

Details. We need details.

Re: Third Diff's a Charm
 

I was trying some to make it up an obsticle only 1's and 2's were doing,:D made it to the top but just couldn't get over,:( gave the throttle a little bump and hoped sideways towards a tree and drop off,:eek: that sideways hop made it so I couldnt back down(big rock behind me) so I gave it another bump to the gas and hop hop POW.:crying: someone get the strap and pull me over the top. was able to finish the day:beerchug: but got it towed to a dealer, waiting to hear from them now:o

Re: Third Diff's a Charm
 

I take it Phil was there??? What were his thoughts?

Re: Third Diff's a Charm
 

Bueller????.....Bueller????

Re: Third Diff's a Charm
 

he was there, trying to spot me up the hill, no one was sure I busted anything at first. there was alot of skid plate being abused at the same time.:p but Terry, who does fab work for hummers,said it sounded like I blew my diff. going down the trail to the next stop I could hear it. kept on going till time to go home. on the road home it was worse so I stopped and called Phil for ideasand he said it was probably busted and to get it flatbeded to the dealer.

BTW anyone who thought putting a hinge on your rear plate would save it. it didnt save mine. by the end of the day mine was like a rolled up newspaper:giggling:

Re: Third Diff's a Charm
 

thanks for the heads up on the rear plate hinge :giggling: atleast you got that research in before busting :p ;)

Re: Third Diff's a Charm
 

2 front and 1 (maybe 2 now) rear for HI :mad:

Re: Third Diff's a Charm
 

I've blown a front diff in my base model and I think the one in thier now is going. I have an appointment for this Saturday morning at the dealer. When I go about 50mph and let off the gas, I hear what sounds like a chain riding against metal. It;s like a chattering sound. Also, my gas mileage has dropped considerably.

Re: Third Diff's a Charm
 

I may have jinxed myself. :mad: :mad: :mad:

The dealer says their area rep has been giving them grief about some of their warranty work. Since this is the second failure of the same part in 6-7 months they're afraid the claim is going to get rejected. They asked me to escalate it with Hummer assistance so they can go ahead with the work under warranty. I'm on the phone with them right now. :rant:

Re: Third Diff's a Charm
 

I also went back to look at the diff. You can see the damage to the pinion gear and some wear on the ring gear.

Attachment 30984

The tech is the same guy that worked on it last time. Since I didn't get to see the damage last time I asked him about it. He said there were chips on both the ring and pinion gears last time, on multiple teeth. They replaced the whole diff last time, housing and all.

Re: Third Diff's a Charm
 

How is that your problem???

Re: Third Diff's a Charm
 

OK, let me just say that Hummer Customer Assistance ROCKS!!!!

So I called up and said I wanted to open up a case since my truck was in for a second diff failure. The lady took my info and said she'd put me on hold while she called the service manager. A couple minutes later she comes back online and tells me everything will be covered under warranty, she'll check back in with me on Monday, and they'll compensate me for the inconvenience. :jump: She said they just want me to be completely satisfied. The whole call took less than 10 minutes.

BTW, I don't really blame the dealership. They suggested I call so we could get past the area GM rep and speed up the process. The service manager had no problem doing the work under warranty.

Re: Third Diff's a Charm
 

Excellent News Sewie! :perfect10s:

I'm glad that they're going to take care of you. OBTW... Did you ask them about replacing with a cast iron unit? Just wondering, especially as the worst thing they could have said was "no"

Re: Third Diff's a Charm
 

The cast iron unit does not exist....this knowledge comes from many hours of futile searching.

Good job Sewie and GM. Who the hell do these reps think they are anyway. It's gonna be at least an hour before my blood pressure comes down after that story. Jeesus!
