Abstract: A rigid drive axle assembly for motor vehicles, includes a support beam member having a substantially flat, enlarged central section and two opposite arm sections axially outwardly extending from the central section, a differential assembly secured to the flat central section of the support beam member, and two opposite axle shaft members outwardly extending from the differential assembly and rotatably supported by the arm sections in a spaced relationship with respect to the central section of the support beam member. The differential assembly includes a differential carrier frame member fastened to the central section of the support beam member, and provided for rotatably supporting a differential case and a drive pinion. The differential assembly is enclosed into a housing formed by a rear cover and a front cover secured to opposite surfaces of the central section of the support beam member. The rear cover incorporates two throughholes provided with self-centering seals.
