Re: Rear Brake/Axle Groan...
 

Mine was built: 04/27/2005. It was almost considered a captured test vehicle. :jump: Only trips to the dealer for H3 service was the top off of the t/case fluid, a new TCCM, and then I had the t/case replaced. For such an early built vehicle, I sure did luck out.

Re: Rear Brake/Axle Groan...
 

I called the dealer today .I emailed them link to video/sound file they could not open it.they said links and attachements are blocked.Im bringing it in friday,they said they have the ears to locate were sound is comming from.They also said the trans case buletin shows no fix ? I said replacment would fix it if thats the problem,he said he dont know?
I will bring my camera with the video/sound file on it also when I go in and hang out to see what happens.

I do wonder were the noise is comming from hopefully they can locate it.


F5 is there any other info I can give them?

Re: Rear Brake/Axle Groan...
 

Noise travels down the driveshaft to the axle and out. That is what I was told today. In my case, the new t/case did fix the problem.

Re: Rear Brake/Axle Groan...
 

Its going to the dealer friday morning ,I hope they figure it out and know how to use the ears properly.

My brother said my noise sounds similar to when you put it in park when your still rolling.:eek:

Re: Rear Brake/Axle Groan...
 

:eek: Yes, :iagree: , that noise is like something you'd hear on some old truck on it's last leg. I know that mine makes a similar sound on the outside because I've seen the expression on people's faces when I come to a stop.

f5fstop, if I haven't already done so, THANK YOU for finding my H3's build date!! Can you really see how many brake pads were put on my H3 through the vin#???

Re: Rear Brake/Axle Groan...
 

All service history, dealer vehicle was shipped to, dealer that sold the vehicle, and complete build history. Also, a branded title, GMPP, but no owner of record. That is another system, that I do not have access to (don't want it either:giggling: ).
Service history is important for researching problems on vehicles.

Re: Rear Brake/Axle Groan...
 

GMPP? :eek: They're not personal remarks put in by dealer service mgrs, are they?? :giggling: I'm sure they had a few words about me and how persistent I was. GG, wait til I have to go back again with my grind/groan. :D

Re: Rear Brake/Axle Groan...
 

:rant: I just got back from the dealer.They hooked up the ears had 2 mechanics out in it and said its definiatly comming from the brakes.Transfer case,axle ect not making noise.They said they cant do nothing they tryed calling hummer tech and couldnt get through.I said I will wait untill they do I have time....They got through to tech and they said they shouldnt have replaced pads at 12,000 miles and cant change pads now.


TAC found no updated parts available//case # 9256114// no repair to be performed at this time.
TAC stated//normal condition of vehicle braking system//metalic brake pads will cause condition.
:lame: :confused:


Anyway the service rep said all he can do for me is to have a hummer rep meet me at the dealer and go from there.
The service manager said he will call me this afternoon to set a day and time.


This is starting to get me fustrated :crying: :(

Re: Rear Brake/Axle Groan...
 

No personal remarks. However, they have set up a new tab labeled "BEBE.":dancingbanana:

Re: Rear Brake/Axle Groan...
 

Different noise than I had, not sure what else to say; except call Hummer Assistance and open up a case.

Re: Rear Brake/Axle Groan...
 

LOL .. as in "HummBebe"??? :jump:

Re: Rear Brake/Axle Groan...
 

Wellllll, this is what happened to me, fourfourto, beginning back last June. I eventually called GM Customer Service and got a case#, going to the 2nd level after the first gal tried all that she could. The gentleman I finally dealt with was fantastic .. a true asset to GM, in my opinion. Anyways, I never DID get to meet with the Hummer tech. Make sure you are there when he is!! I'm sure it will make a difference to get your opinion in on it. A Hummer tech/rep happened to be there on another case, so looked at mine, too. No one told me. :rant: My GM Cust. Srv guy told me what the Hummer rep reported .. basically the same as your report from the dealer today. He did, however, strongly encourage me to try another Hummer dealer, which was a real pain in the rear, for me. I did, however, and had great satisfaction until I began hearing it coming back somewhat over the last couple of weeks. PLEASE post what happens once the Hummer tech/rep talks to you and sees your H3! When I decide on when to take mine in, I'm going to have them use the Chassis Ears on the t/case and see what they say. Do you think you'll be seeing the rep next week? Good luck! Stay determined!

Re: Rear Brake/Axle Groan...
 

The service rep just called he couldnt get in touch with the hummer rep yet said he will call me on monday.
I will see what happens with the hummer rep before I call hummer assistance.
The service rep says maybe he will have some sugestions on what to do?.


F5 thanks for all the help it would have been easyer if my transfer case was bad,but its not likely unless they didnt check the noise properly,butI think they did?
Any info on brake troubles you come accross let me know.
Is there anything I could mention to hummer rep to get somewhere with this?

Hmmm3 did hummer assistance or rep tell you anything but try another dealer?.
My dealer will probobly do anything they have to if they get ok from hummer?

Re: Rear Brake/Axle Groan...
 

If it is really metallic brake noise, replace the pads with pure organic brake pads. They wear faster, but for rears that should not be a big factor.
But the strange thing is all of us have the factory rear brake pads, and only a few have this noise.

Re: Rear Brake/Axle Groan...
 

There must me more to it then the pads.
I am determined to get this figured out even if I have to eventually take it apart myself.

Re: Rear Brake/Axle Groan...
 

I wrote a lonnnng post here and decided to delete and just answer your direct question without getting so wordy. Bottomline is that if the GM/Hummer tech rep reports that there isn't a problem, or, that it's normal for an H3, or has zero safety concerns .. Hummer Assistance can't do anything about it. Hummer Assistance said they have to go by what they are told about the vehicle by their field person since they are the field experts. I was really upset, especially since I had other issues with my H3 all along the way (cylinder head/valves, hood repaint, air intake box repaints, engine light, stabilitrak, etc., etc.) The dealer can't make the 'fix' if the field rep doesn't approve any fix. When I went to the other dealer, the made a fix and it had been gone for a couple of months. (The groan is coming back, especially when I have to brake suddenly. Mine used to sound as bad as yours (sorry!), but is now just building momentum again. (:eek: )I'm going to let it build before I go back again. I may try the 3rd dealer next time.) let us know what happens with the field rep!

Re: Rear Brake/Axle Groan...
 

I"m going to have to quit reading these trouble threads as every time I do my truck develops the problem. Mine just started the "groan" this week at a little over 11K miles. Sounds just like 442's sound files.....:rant:

Re: Rear Brake/Axle Groan...
 

lotus4s sorry to hear you got the grown,maybe your dealer has a tech thats smart enough to figure it out.Do you know your build date ?.
Keep us:grouphug: updated.

Re: Rear Brake/Axle Groan...
 

Don't know the build date but I bought mine in late Feb 06.
