A modular axle assembly incorporates a separate bearing support plate which is received at an open end of an axle housing. The separate bearing support plate supports the bearing at the open end, and is received within the open end of the axle housing. In the prior art, the large helical cover typically also provided the bearing support. The use of the separate bearing support plate allows the modular assembly of the axle assembly and further facilitates repair. In another feature of this invention, a threaded adjustment member is associated with both the bearing at the open end of the differential, and also with the bearing at the other end of the differential. The threaded adjustment members allow the control of gear positioning and the pre-load on the bearings such that precise positioning and pre-load adjustment are easily obtainable.
