A power train assembly has an engine oil sump housing 51 with side walls 51a, 51b, 51c, 51d, 51e, and a differential 30 with a cage 33 coupled for rotation to a crown wheel 31 rotatably supported on side wall 51a by a single bearing 40. An inner bearing race 42 can be integral with the crown wheel 31. An extension 58 of a side wall houses an input pinion 37. The single bearing 40 can aligned with the centroid line of the differential (between the input pinion and the engine oil sump); with a rotational axis of spider gears 35a and 35b; with the crown wheel 31; or parts of a differential cage 33. A lightweight cover 60 (of plastic or metal) is mounted to a side wall to enclose the differential, and thus a separate differential housing is not needed.
