An axle assembly includes an upper and lower housing joined to form a chamber for a differential gear assembly. The upper and lower housings are fabricated by a method including the steps of forming the upper housing from a first sheet of material and forming the lower housing from a second sheet of material. The upper housing includes an opening for the differential gear assembly and the lower housing includes a bowl portion disposed opposite the opening. The upper and lower housings are joined by a weld to from the axle housing. The lower housing includes leg portions that form a single unified structure with the bowl portion to improve structural rigidity and simplify assembly.
