Abstract
A differential is sealed such that it retains its own lubrication fluid supply. The carrier housing is formed from two carrier halves which are welded together. One carrier half has an inner axial extension which is radially inside an outer axial extension of the other half. A circumferential weld is placed between the outer axial extension and the first carrier half. One of the stub shafts has an end cap with a one-way valve to allow fluid to be added after the welding is completed.
