Just wanted to give an update on the clunk. The noise was coming from a variety of locations, most notably the skid plate and some wires underneath. Apparently if the skid plate is lubed that well, it can twist and make this type of noise. Also, if thes wires get pulled in a turn or brake, they pull down on a cross member and it can make that noise.

These are the explanantions from the dealership. We will see if it holds up.
