Abstract
A suspension linkage for an axle has hard mechanical oscillation stops that move relative to the vehicle frame as the axle travels vertically. The linkage uses thrust bearings to eliminate sideways movement of the axle that causes bounce steer. The linkage is a scissors linkage, having an upper link and a lower link joined together at a center pivot. The hard mechanical oscillation stops are carried by the linkage, as opposed to the vehicle frame, and thus move vertically with the axle.
