Swing axle

An independent rear suspension system in which each driving wheel can move up or down independently of the other. The differential unit is bolted to the frame and various forms of linkage are used upon which to mount the wheels. Drive axles, using one or more universal joints, connect the differential to the drive wheels. When cornering hard, cars with swing axles are prone to wheel jacking which can lead to large positive camber at the outside rear wheel and can induce sudden oversteer. See also low pivot swing axle.
