It would also make sense that I felt it for the first time last night because it has been raining hard up here in the Northeast for the whole week and last night was the first time I drove the H2 since Monday (when it was dry out), so the body mounts might have been wet and more prone to "slip". I will see if it stops today or tomorrow now that we have dry weather here. If it does stop "clunking", then I think this comes close to proving that it is the body mounts.

Thanks again, and if anybody else disagrees and/or has any other ideas, I would certainly still welcome them.
Sun-

I had the same issue in my 2006....dealer couldnt find the source since it was so intermittent. So i fixed it myself and bought a 2008...lets hope i doesnt happen with the new one. I recall someone posting on here that if you torque the body mount bolts a bit it will stop the clunk/creak.
