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.
