Small Problem........anyone know what this could be?
 

On my 2007 Hummer H2........I have noticed when i am making turns, it has a "popping sound" almost as if the body is loose from the frame. Its been doing that quit sometime, but I have never taken it to the dealer to get it looked it. I have noticed it seems to be getting worse. It has 30,000 miles on it.

Yesterday, when I was driving my 2008 Hummer H2, I noticed its starting to make the same popping noise.......just not as loud as my 2007.

Its almost like you can feel if under the driver floorboard area with your foot sometimes. It only does it when I am turning. As long as I am going straight, its quiet.........and the popping dont do it on all turns.......but on most turns.

Any ideas? or anyone eles's H2's doing this?

I am gonna take them down to my local Hummer Dealership and have them look at it.

cant remember what the issue is but it has been discussed on here before.

Re: Small Problem........anyone know what this could be?
 

My 08 H2 does the same thing. Let me know what the dealer told you.

Body Mounts

Re: Small Problem........anyone know what this could be?
 

Yes, there are threads on this. One has you silicone lubing and adjusting the body mounts and another by HumTech has a fix where you take out the battery and give it a few pops in that area with a rubber mallet. One other was told by the dealer that it's a common problem of oil canning with the floorboards and comes and goes as temperatures change. SUVs seem to do this much more than SUTs. Take your pick!

Check your Transfer case mounting bolts.

Took the 07 to the dealer yesterday, and picked it up today.........it was the body mounts..........problem fixed under warranty.

Re: Small Problem........anyone know what this could be?
 

Took mine in today. It was the body mounts also. Fixed under warranty. In addition the dealer said that GM had issued a service bulletin for that. They also replace the front break pads.The front passenger side had developed a squeal. GM issued a service bulletin for that also.

Ice, any chance you can get the GM service bulletin #'s from the dealer for both issues (body mounts and front break mounts)? I've taken my 2008 H2 in for both of those issues over the last 9-10 months. On the 'popping' sound, they say they can never replicate the noise, so they won't fix something they don't hear. And, as you know, the sound didn't happen all of the time. And, my brakes sqeal everytime I come to a stop. They replaced the pads/resurfaced the rotors once, but said they won't anymore because it's a "Hummer thing". <grrrrr> Thanks just in case you can get your hands on those numbers. No worries if you can't.

Body mount bulletin: 070861006C
Brake bulletin: 080523004
They were referenced on my service order.
Good luck!
