  • Differential lubrication feed system in a drive axle assembly
    Patent number: 8409044
    Abstract: A method for lubricating an axle assembly can include: coupling a pair of tapered roller bearing to opposite ends of a differential housing; placing the differential housing into a carrier housing assembly such that the tapered roller bearings support the differential housing on the carrier housing assembly for rotation about a first axis; collecting a lubricant proximate a side of one of the tapered roller bearings opposite the differential housing; and rotating the differential housing about the first axis to cause the one of the tapered roller bearings to move a portion of the collected lubricant through the differential housing. A related axle assembly is also provided.
