I have a 1996 Dodge Ram 1500 2WD that pulls to the right pretty hard. If it was just that then I would think that it was an alignment issue. It also shakes violently. Once I get to about 40-50 mph (maybe it would do it when it gets faster too but I am too afraid to go much faster) it starts to wobble. The steering wheel wobbles back and forth and the whole truck does too. If I let off on the gas it will lessen the wobble. Also if I am going around a curve to the right it starts to wobble really bad. I have looked at all the joints and such and everything appeared to be ok. Also rotated the tires to make sure it wasn't a bad tire. What could this be?
