Abstract
A pivot bushing for a suspension system has an inner metal and a split outer metal with an elastomeric bushing disposed between the metals. The split outer metal has one end which is partially closed by an inwardly curved portion and one end which is open. The assembly of the bushing is through the open end. Once assembled the open end is closed by placing a cover over the open end and crimping the cover to a flange formed at the open end. In another embodiment, the cover is inserted into the outer metal and the split outer metal is crimped to secure the cover in place.
