Abstract
A pivot bushing that is assembled into an eye of a leaf spring includes an anti-walkout device. The anti-walkout device comprises a retaining ring molded into the elastomeric bushing which is a part of the pivot bushing. The retaining ring is larger in diameter than the eye of the spring such that any tendency of the spring to walk off the pivot bushing is resisted by the retaining ring. The retaining ring is located at only one side of the elastomeric bushing because a leaf spring always has a tendency to wave off the pivot bushing in one direction.
