ABSTRACT:
A steering mechanism includes a relay rod and an idler arm operatively attached to a first end thereof. A pitman arm includes a stud and is operatively attached to a second end of the relay rod. A bushing is configured to allow displacement of the pitman arm relative to the relay rod. The bushing includes an outer can, an inner metal member, and a bushing disposed therebetween. The inner metal member has a tapered receptacle configured to mate with a tapered portion of the stud. The resilient member may include voids, which may be oriented generally perpendicular to a turning direction and may be tapered from the base to the opening. The inner metal member may have a generally-cylindrical portion and substantially-opposing outer flats interrupting the same. The outer flats are spaced by a distance smaller than the cylinder diameter and may be substantially parallel to the turning direction.
