Cross-axis joints are primarily installed on the rear axle. They consist of a ball with cylindrical taper on both sides and a continuous bore in the middle. Although they are similar to the ball joint in terms of function and structure, their anchorage corresponds to that of rubber bearings. In contrast to rubber bearings, cross-axis joints are able to transfer extremely high dynamic forces and have no aligning torque. Cross-axis joints are preferably used if a stiff control arm connection is desired – in sports cars or light commercial vehicles for instance.
