Abstract
A suspension assembly of an axle/suspension system for a heavy-duty vehicle is mounted on the heavy-duty vehicle frame or sub-frame via a beam of the suspension assembly which is pivotally connected to a hanger connected to the vehicle frame. The pivotal connection includes the hanger, the beam, a bushing assembly and a fastener group, and a textured feature formed in at least one of at least a portion of the hanger, at least a portion of the bushing assembly, or at least a portion of the fastening means so that the textured feature inhibits relative movement of the bushing assembly with respect to the hanger.
