A bushing for use in a vehicle suspension system, the bushing including a cylindrical sleeve including an internal passageway extending from first to second ends of the sleeve, the sleeve dimensioned to receive a shackle bolt therethrough; an elastomeric member at least substantially surrounding and extending radially outwardly from an exterior circumferential surface of the sleeve, and the elastomeric member having a pair of spaced-apart, circumferential channels positioned between the first and second ends of the sleeve and opening outwardly away from a radially outermost exterior circumferential surface of the elastomeric member, the channels dividing the elastomeric member into three radially-extending portions, one of which radially-extending portions is intermediate the other radially-extending portions; a rigid retainer ring positioned over the intermediate one of the radially-extending portions, the retainer ring having spaced-apart sidewalls extending into the circumferential channels so as to capture only the intermediate one of the radially-extending portions therebetween; lubricant disposed between the retainer ring and the elastomeric member; and a housing surrounding an exterior circumferential surface of the elastomeric member and the retainer ring, with the retainer ring positioned between the housing and the exterior circumferential surface of the elastomeric member. The bushing, including the housing, cylindrical sleeve, elastomeric member, retainer ring and lubricant, constitutes a single unit that is receivable in, and removable from, a vehicle suspension system.
