davebloomer: someone might verify this, but I believe axle wrap is when your pinion angle changes due to the axle "wrapping" or rolling. I was getting some pretty bad vibrations when I was out there, but I'm unsure if it was axle wrap or if it was wheel hop. I think my PSI was too high on the tires...they seemed to be the problem but I really was never 100% sure.

So RuBob, not sure if I was getting axle wrap or not but the ESP does become a pain in the ass out there. I really need to put a manual killswitch so I don't have to have it in constant 4 Hi because you really don't need it.
