This noise is driving me crazy!!!

Interesting, try posting on the H2 side and see if anyone there knows. Could be a tire wheel out of balance issue.

A few people had noisy body mount issues when the H3 first came out. I thought they were resolved after the 2007 models. The noises were either in the back by the tires or under the floorboard by the brake pedal. Several posts in those days described it as a loud oil canning type popping noise and had it resolved by replacing the body mounts.

We had that same problem with our 2006 H3. You wouldn't get it all the time and almost never in the rain. When it pops you can feel it in the floorboard and it's loud. The dealer suggested spraying the body mounts with silicone spray and it only helped marginally for a month. They finally replaced the body mounts under warranty and the noise disappearred.

I sprayed my two right rear body mounts with Fluid Film. They have been quite since then. I just wonder how long it will be before it starts making noise again.
I'll have to try to explain to the dealer that I want the TSB performed with the new body mounts. Unfortunately I like in redneckville, so they probably won't understand......
