At least one end of a longitudinally extending control link arm includes a
laterally extending tubular portion that receives a bushing assembly. The
tubular portion is used to pivotally secure an end of the control link
arm to a vehicle structure or axle component. The bushing assembly is
positioned within the tubular portion such that radial stiffness is
distributed away from a center of the tubular portion. This configuration
provides a high conical rate and provides auxiliary roll stiffness such
that a sway bar is not required.
