    Abstract: A bushing is configured for installation in the hole of a lug, which has a protrusion extending radially inward from a surface of the hole. The bushing includes a first cylindrical body that is sized to be received within the hole of the lug. A flange extends radially outward from one end of the first cylindrical body, and a first recess is formed in the first cylindrical body to a radial face. The recess is sized and configured to receive the protrusion of the lug when the bushing is installed in the hole. Engagement of the protrusion with the recess preventing movement of the bushing relative to the lug.
