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.

Re: Rear Brake/Axle Groan...
 

Lotus4s ... look at the decal on the drivers side, inside door jamb. The build date is on the upper right hand corner. Fourfour2 and I both have the same build date .. we both have '06's. The groan in my H3 sounds just like fourfour2's also. It could be something inherent to our build date. Please check when you can. If we :grouphug: , we may be able to find the problem. Thanks!

Re: Rear Brake/Axle Groan...
 

Build date according to the sticker is 09/05......thanks for that info.

Re: Rear Brake/Axle Groan...
 

lotus4s, well, your build date is not the same as mine or fourfour2's. Ours was built on 6/22/06. It looks like you'll have to go the same route as we did .. and, f5fstop, and have it checked out. Read the posts on this thread .. make a copy of the bulletin regarding this sound closer to the top of this thread and take it with you to the dealer. PLEASE keep us updated as to whatever you find out from your dealer. We're ripping our hair out already for a number of months trying to figure this out. So far, f5fstop has had his fixed.

Re: Rear Brake/Axle Groan...
 

WHa????:giggling:

Re: Rear Brake/Axle Groan...
 

:jump:


As of right now I'll probably wait until it gets worse or something else comes up to take it in as it only does it on hard stops, but I will keep you guys/gals posted.

Re: Rear Brake/Axle Groan...
 

F5
If its not to much trouble could you see if theres any memos ,bulletins or any complaints on the brakes.

Also Im guessing that the brakes are the same on the 2007.

Hopefully the service reps on the ball and calls me monday with a apointment to see the field rep.
The only fix or repair I would be happy with would be new pads ,new rotors, new calipers.
Im sure they will replace everything or do nothing and continue to say its normal.

Im hoping for the best and will go in with a good attitude :D ,I might not leave that way.:mad: Grrr grrr ...

Re: Rear Brake/Axle Groan...
 

Good luck, fourfourto. I got new brakes/pads, but the rotors were turned again.:mad: But, as you know, my groan is coming back (in more ways than one!) Hope you hear something on Monday.

Re: Rear Brake/Axle Groan...
 

No call from the dealer today :mad: I will give them a couple days:yawn:

Re: Rear Brake/Axle Groan...
 

Uhhhh-huhhhh....well, don't wait too long. very frustrating, I know.

Re: Rear Brake/Axle Groan...
 

I called the dealer to see whats up and they told me they left voice mails and emails to the hummer field rep they got no response as of today.
They said they didnt forget about me they will contact me soon,the rep takes a while to get in touch with.

So I will give it time and see what happens when I get to see the field rep(If I ever get to see him)

Why would it take a week to contact a field rep :confused:

GRRRr Grrrr :mad:

Re: Rear Brake/Axle Groan...
 

I have no idea..obviously it shouldn't, in my opinion. GM Customer Service told me that they are regional when I complained that I kept getting the same response you just told me. He said he'd look into it. He called me back and said that all the field reps were away for a two week period (meetings?) last June and that was why I had been waiting. However, as you know, I never DID get to talk to the rep who looked at mine. They did it themselves and told me the outcome after the fact.:rant:

Re: Rear Brake/Axle Groan...
 

Well, if they are talking a regional service engineer, there are not enough to go around. Top of my head....twenty to cover the entire country.

Re: Rear Brake/Axle Groan...
 

I could be wrong, but I don't think they sent a regional engineer. They kept telling me he/she was a GM field rep. The one who looked at mine was a 'he' and GM Customer Service told me that he was based in the Sacramento area. There were two possible reps who could have looked at mine .. so that means there were at least two who rotate S. California. After talking to my serv. mgr, he found out which one looked at my H3. Maybe fourfourto will get a service engineer!:D

Re: Rear Brake/Axle Groan...
 

In 442's neighborhood, I know three of the regional service engineers (maybe four), who I worked with for many years. So, 442 if you get one out there, give me his name.:dancingbanana:

Re: Rear Brake/Axle Groan...
 

Thanks F5:D If I get his name and email add before going in I will PM you it.:shhh:
I was thinking of emailing rep the sound files also before meeting with him.
When I hear from the dealer Ill try to get that info from them.
If I dont hear from the dealer by monday I will give them another call and try to get name and email of rep.

For now a temporary fix is keep the radio on feather the brake and live with the GRRRr Grrr :o

Re: Rear Brake/Axle Groan...
 

Ohhhhhhhhhhhh mannnnn .... now you have an 'in', fourfourto!! :D Well, at least, I'll get to hear what the problem is from you once they figure it out, then take it from here MYSELF! (:giggling:)

Re: Rear Brake/Axle Groan...
 

:rant: Its tuesday I just called the dealer they didnt get a call back yet from field rep(said they think hes on vacation :confused: )
They will try again today .They wouldnt let me know his name(they said the reps dont like to give there names out )
If I dont hear from them by friday I will call hummer assistance and see what they can do on monday

The dealer said there not sure what the rep could do since there is no fix to the problem yet.I told them something has to be done I cant live with the noise

There has to be a record or something with the brakes since others have the same problems.
Any Idea's ?




GRRR Grrr :mad:

Re: Rear Brake/Axle Groan...
 

Well, you could do what I did the first two separate times I began hearing it in mine. When they said they didn't know what it was .. I handed them the keys and told them I would not drive it .. I thought it could be a safety risk. They said they were 'pretty sure' it would be okay to drive. "Pretty sure' made me feel uneasy. So, I took a loaner. They fixed the noise for 2 weeks .. and then it went back again. I asked for the loaner again. That was MY beginning to all of this. They didn't like it sitting there since GM gets the bill for the loaner. Finally, it was during that down time at the dealer that the field rep had shown up.

Re: Rear Brake/Axle Groan...
 

hey,

today for the first time i heard the sound, but i got two different sounds.

I have one where it groans rite before the truck stops during a hard brake. I think thats normal, just the brakes slipping maybe not, but thats not what im concerned with.

The second sound comes rite after the truck stops and as the rear end drops down. Its not too loud and it has a ratchet type sound. I also have the exact same sound when i shift from park into drive/reverse.

f5fstop, does the transfer case one sound more like the first or second i described? Did you also have the sound when shifting park to drive/reverse?
did your sound occur as the rear end drops after hard braking or as it stops.

im gona see my dealer soon, but from what i've been reading around here about this sound, im gona get ready for some hard headed bs.:)

thanks!

Re: Rear Brake/Axle Groan...
 

Does it sound like the video / sound file I listed on this thread?
