A strut assembly including a reservoir tube that extends about and along a center axis and has an interior surface and defines a chamber. A bearing sleeve is disposed in the chamber of the reservoir tube and extends about and along the center axis between a proximal end and a distal end. The bearing sleeve presents an inner surface and an outer surface. A damper body tube is disposed in the bearing sleeve and is moveable relative to the bearing sleeve. A piston assembly is disposed in the damper body tube. The outer surface of the bearing sleeve has a tubular portion and a protrusion portion that extends radially outwardly relative to the tubular portion and annularly and providing an interference fit between the outer surface of the bearing sleeve and the interior surface of the reservoir tube.
