Thats wrong! I had the same clunk with my H2. It Only happened right when you take off from a stop. The noise you here is the drive shaft yoke knocking and binding with the tail housings main shaft. The problem is excessive drive shaft yoke lash against the spline. Most Hummer H2s do this but most owners don't notice. My dealer Replaced the Drive shaft and front yoke with a new updated longer one from GM. They also replaced the rear tail housing of the transfer case to get a updated seal installed for the new drive shaft yoke. DOn't take no for an answer, throw it back in there face and make them fix it! BIG-C
