Hope this is not true. Moog Offset Upper control arm bushings.

An example, - take an ordinary open house door hinge, straight up and down, on a tabletop, one side is the frame, the other, the wheel, pivot being the kingpin, it swings both ways, left turn, right turn, - lean it 30* (add caster) and flex it, at some point it lifts the kingpin/frame , - the more lean(caster) - the more you're lifting the frame/car .

When you release the steering wheel after a turn, you let go of the "jack handle" holding up one side of the car .
