Well thanks SPAZZ.

Mine's been running with the noise since the weekend before Moab. Nothing bad has happened yet. I assume that at some point something will break and I'll be paying to fix something.

I did notice that when I had a load in the back, I couldn't hear the noise. I don't know if that was because the load was moving the back end closer to factory specs or if stuff I had back there was just an excellent sound absorber.
