I agree on too much body seperation. and the shocks are not doing thier job. how old are them shocks. I went though this with freds car. and found out the shocks was just wore out. same shocks. Got him tieing the car down in the trailer by the body now. he was tieing it down by the rear end and it was bouncing in the trailer wearing them out ! and border line on the air in the tires.
