Yep, noise, loose, they are most likely causing it. Did you check them yet? Grab a flashlight and screwdriver and go check them! What are you waiting for? You need to find the problem so you can rest easy tonight!

A friend has it, looking for an electrical problem for me. I'm going over there Monday, I'll do it then after putting on a hitch.

Thanks Mike.

So...a few bad joints, a sour rear differential, and a transfer case issue. Thats all the vibration is. Nothing major. JUST A REAR END! Oh, but my lights work now!

Guess I get to upgrade to a D44. Lets go look for one!
