Rearend replacement

[KenP]

Locally, our dealer has two trucks needing new rearends. Hall was originally going to repair them, but GM said to replace the WHOLE thing! It seems this may not be an isolated problem.

Anyone else with this problem?

I found out today what the cause was - workers on the line did not wash out the sand cast rear cases and sand is in the case eating at the bearings. It take milage to make the noise. Over 3K to be exact...Mine is effected along with a lot of early production models. I will have to replace ours as well.

How about the front end?

While washing my H3 last night, I noticed that the front-right wheel well seemed a bit loose. I saw the staples that everyone talks about (yuck), but the big part was the flex in the well while washing it. Any suggestions?

Thanks!

It looks like I am about to join this club as well. Heard a whining noise in my new Black Lux H3 and took it to the dealer. Rear end replacement.......no idea on turn around time yet!!

My fathers H3 needed a new rear end after 600 miles. Heard a whine in the back and metal fell out when the cover came off. They are replacing the whole unit but I dont know if they completed the work yet. It was going on two weeks in the shop.

Unless there are two faults, Hummertech posted the correct cause yesterday in another thread.

Hummertech posted this information:
"The problem with the rear ends is simple and it could be in any vehicle with any optiions. The problem is this, the supplier that supplies the axles for GM had a batch of them go out that did not have the lapping compound cleaned off the gears. This compound is gritty, and after a thousand miles will chew up the bearings some.
It is all covered under warranty, no easy way to tell if yours is affected or not without just driving it and seeing if a noise develops.
Sorry but some of you will have the trouble of having to get this fixed. Many will not. At least it's not a design flaw or something more serious. Just an idiot at the GM supplier."

This was confirmed as the problem before I even read the thread from Hummertech. The problem can come a lot earlier than 3K miles. Some have failed at 1K.

the law states that if a replacement part on vehicle is unavailable from a manufacture (DOES NOT MEAN BACKORDER DOES NOT COUNT, they must supply you a vehicle unto the part is available....

The service tech wrote me an email today saying his boss called Hummer and "we are waiting for G.M. to release differentials. Till then we wait". Doesn't sound like the dealer is willing to rattle any cages at corporate to get me fixed quickly. I wouldn't mind doing some calling myself. Maybe I can get some action going. Anyone have any suggested phone numbers and/or contacts for me to call?

Mine needs a new rear end. Dealer finally figured it out yesterday after almost a month of me complaining about a knocking noise. They showed me a bulletin dated yesterday from Hummer that says rear-end replacements are now on hold until they can figure out why so many are failing. The dealer is telling me I will have to wait until GM figures out a solution.

In case any of you read my others threads regarding a knocking noise that is only heard when the truck warms up. Or you may have read my complaints about excessive vibrations coming thru the gas pedal. When the dealer has diagnosed the rear-end as the culprit. Now am just playing the waiting game until Hummer comes out with a solution. I plan on bugging them about every 2 weeks until its repaired. In the meantime I am driving around with the issue.

[richk]

Mine began making occasional weird noises after only 500 miles. Now I am just over 2k and it keeps getting worse (cluncking/vibration/etc). If the deterioration keeps it current pace it may not be driveable in about 3-4 weeks.

[Vegas-H3]

FYI... I also was at a little more than 500 miles when this happened. With the Monsoon system on, it's harder to hear the noise, so keep a look out for it. (Hopefully, it won't happen to your ride)!

PS

Did you show leaks too? and do you have the lock rearend as in the adventure package. I don't have that package...

[H3Lady]

I just ask my brother who is a litagation attorney and he said it's part of the Lemon law...

I am not an attorney...so I don't know the details. I just asked him for the hell of it..

Ugggh this is so tiring after a while....did I say that out loud??
