(1) tires not balanced
(2) tires not round.
(3) centre of tire is not true, which equals changing contact area.
(4) steering box slop
(5) there is nothing wrong with running a stabilizer. They come stock from the factory. A real tiny out of balance issue can become nasty due to nothing more than harmonics.
(6) king pin inclination being different from side to side, contact pattern, out side or inside of the centre of the kingpin contact point ( draw aline down the kingpin to the road surface) can also create a death wobble issue.
(7) A majority of the time the issue is a loose part or fitting, followed by tire / wheel issue , followed by weird stuff that is almost impossible to track down.
