Abstract
A vehicle driveline component having a housing, a shaft received in the housing, a lubricant pathway coupled to the shaft for rotation therewith, a sleeve disposed coaxially about the lubricant pathway, and a fluid feed conduit coupled to the component housing. The lubricant pathway is disposed helically about an exterior surface of the shaft. The sleeve has a feed port. The fluid feed conduit having an outlet that is in fluid communication with the feed port. Lubricant in the lubricant pathway that has been discharged from the outlet of the fluid feed conduit travels in a predetermined axial direction along the rotary axis of the shaft when the shaft rotates about the rotary axis in a predetermined rotational direction.
