Rear Brake/Axle Groan...

[marin8703]

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!

The one sound where is rite before the truck stops sounds like the sound files, except alot quieter.

Then rite as the rear end drops there is another sound, kinda ratchety and also not too lound. i have the same sound also when shifting into drive or reverse. That seems like its also coming from the back.

The second sound im talking about is really amplified when in a parking garage, sounds 10 times louder.

Did you look at your rear suspension shocks leafs ect.

Otherwise it could be the brakes.
The dealer said my noise is comming from the brakes... But what do they know.I think its the brakes because it stoped after they cut rotors and put on new pads ,6,000 miles and noise is back

Bring it in to your dealer maybe some teck is sharp and will figure it out?.

My dealer says theres no fix its normal,
Im still trying to get appt with a field rep(2 weeks nothing).
I might call hummer assistance friday or monday.

Well I just called the dealer ..again
He said the rep still didnt get back to him about my problem.
The service rep did say he spoke to field rep last week when he saw him at the dealer. The field rep said he would get back to serv rep and he still didnt at this time.

I dont understand he talked to him at the dealer.

I just called hummer consumers relations at 1 866 486 6376

I got a file # and was told I would hear from a manager within 2 days.

So I will see what happens again
Hopefully something will come of this.

Geeeez, fourfourto. Why was the field rep out at the dealer and didn't set up an appointment to see yours? And, why did your dealer say last week that he thought the field rep was on vacation? I got the same runaround. The field rep just happened to see mine while checking out another H3 .. and they never called me. I am MORE than curious to hear what GM Customer Service will tell you in two days. I called 866-790-5700. You have a different # for them? If the first level person at Customer Service can't seem to help you, tell him/her you'd like to 'escalate' your case to the next level up. The next person above him/her has more authority. But, you have to get through the first person first. Good luck and PLEASE post any progression!

Im not holding my breath

The # I used was listed here by F5 they probobly go to the same location.

The phone rep said thank you for calling cadillac I said its a hummer she said sorry thanks for calling hummer
