An axle assembly having an axle housing, an input pinion, a ring gear, a ring gear bearing, a differential assembly and a pair of axle shafts. The input pinion is mounted to the axle housing for rotation about a first axis. The ring gear is received in the axle housing and meshed with the input pinion. The ring gear bearing supports the ring gear on the axle housing for rotation about a second axis. The ring gear bearing has a bearing race, which is integrally formed with the ring gear, and a plurality of first bearing element that contact the first bearing race. The differential assembly has a differential case, which is coupled to the ring gear for rotation therewith, and a pair of output members. Each axle shaft being coupled for rotation with a corresponding one of the output members.
