Rear Brake/Axle Groan...

[fourfourto]

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?

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.

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.

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. ( )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!

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.....

Keep us updated.

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 , we may be able to find the problem. Thanks!

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