Welcome to the dreaded Death Wobble (DW). I've generally found that a worn or loose part allows a bump to escalate into full-on DW. Most common is a loose or worn out front trackbar.

Have somebody turn the steering wheel to full-lock while you watch both ends of the front trackbar. Have your helper bounce the steering wheel back and forth off of full-lock quickly, this will reveal any play in the ends of the trackbar.

There are other causes, like loose or worn out control arm bushings, bad unit bearings, etc.

	Track bar A track bar is a component of a car suspension system that provides lateral location of the axle. While the purpose of the rear suspension of an automobile is to allow the wheels to move vertically with respect to the body, it is undesirable to allow them to move forward and backwards, or from side to side. It is this latter movement that the track bar is designed to prevent. It is a simple device, consisting of a rigid bar running sideways in the same plane as the rear axle, connecting one end of the axle to the car body or chassis on the opposite side of the vehicle. The bar is attached on either end with pivots that permit it to swivel upwards and downwards only, so that the axle is, in turn, allowed to move in the vertical plane only.
