Abstract: A monotube strut assembly includes a housing tube with a piston assembly fixed relative to the housing tube by a piston rod. A damper body tube is reciprocally carried in the housing tube and is slidably engaged with the piston assembly. A bearing sleeve is fixed in position within the housing tube and seals are carried at both first and second ends of the bearing sleeve. A bearing is positioned adjacent each of the first and second ends of the bearing sleeve and the bearings slidably support the damper body tube. A quantity of oil is carried between the damper body tube and the bearing sleeve providing lubrication between the bearings and the damper body tube.
