An electric drive system in a battery electric vehicle (BEV) includes an output shaft, configured to couple with a drive wheel of the BEV, having a face gear at a distal end; a differential, including a pinion gear cage receiving pinion gears rotatably connected to the pinion gear cage via gear pins, having radially-outwardly-facing gear teeth that are oriented at a non-zero angle relative to an axis of rotation; and a housing receiving the differential that is configured to couple to a rotating electrical machine of the BEV, and engages the radially-outwardly-facing gear teeth preventing radial and axial movement of the differential relative to the housing, wherein the pinion gears engage the face gear and permit angular displacement of the output shaft relative to another output shaft.
