Abstract
A bushing includes a cylindrical body and a flange extending from the cylindrical body. The cylindrical body has an inner face defining a bore. The flange includes an outer rim and a face extending radially between the bore and the outer rim. At least one groove is formed in the face. The at least one groove extends from a first end intersecting the bore to a second end adjacent the outer rim such that grease supplied to the bore of the bushing is able to flow through the at least one groove.
