Abstract: The present invention discloses a differential axle housing which is particularly adapted for use in a fork lift and by which productivity is improved and which can be produced in a manner minimizing the wast of materials. Its differential housing has a generally cylindrical roll-forged ring portion having open ends along an axis, and a cover closing one of the open ends. A pair of straight cylindrical flange portions, preferably roll-forged, are attached in diametrically opposite relation to each other on the peripheral wall of the ring portion, each surrounding an axle opening therein. These elements are welded to the ring portion after being individually formed. Thus, the differential housing is produced. A pair of axle tubes are then shrink-fit and welded to the respective flange portions, and fitting brackets for receiving the mast pivot brackets of a fork lift mast are attached to the respective of the axle tubes.
