i had the same trouble with my double cab long bed 2wd, but it only seemed to do it between 65 and 75, or until I switched lanes from the fast or slow lane toward the middle lanes, i commented to the dealer about it, and they also said they've heard similar complaints about it, and Toyota was looking in to it. They lowered 3psi on all tires and it took care of most of the problem it still jumps, but not as often. I understand is a truck, and I enjoy the ride quality on it, specially how crappy the roads are around where I live, but I can dare say is almost a Lexus like ride.
