ABSTRACT:
An annular propeller shaft (10) for transmitting torque from an automotive ehicle transfer case to the rear axle of the vehicle, the propeller shaft having an internal spline (16) which receives an externally splined portion (18a) of a drive shaft (18) at its torque input end and which is adapted to receive an externally splined portion of a slip yoke of a universal joint at its torque output end. The torque input end and a major portion of the length of the propeller shaft are surrounded by an internally lubricated housing (12), and the drive shaft is rotatingly support with respect to the housing by a ball bearing (20). The propeller shaft is rotatingly sealed with respect to the housing by a seal (32) and is rotatingly supported with respect to the housing by a sealed for life, internally lubricated ball bearing (28) which is positioned outboard of the seal. The outboard ball bearing is protected from contamination from external debris by an annular sheet metal guard housing.
