ABSTRACT:
A multi-speed drive axle assembly wherein the differential and planetary gear mechanism are mounted within a differential case rotatably mounted within a carrier secured to the drive axle housing. A plurality of lubricant inlet and outlet passages are provided through the end walls of the differential case to improve the flow of lubricant to and away from moving parts that are substantially enclosed by the differential case. The lubricant outlet passages are preferably located radially outward of the hub mounting the differential case and disposed at an angle to enhance the flow of fluid. A constant source of lubricant is also provided for the interior of the differential case.
