Abstract: An axle bearing suspension system and method has a pair of elongated beams having an upper section and lower section with T-shaped cross sections. The T-shaped cross sections are welded together to form beams having an I-beam cross section. The beams have attachment portions which are preferably arc shaped cylindrical portions for fixing the beams to the axle with the upper section being welded to an upper part of the axle and the lower section being welded to a lower part of the axle.

Abstract: A method of fabricating an axle for use on a truck body or trailer by machining and fully finishing, the components before friction welding results in an axle that is ready for use upon assembly of the components. Beam ends are friction welded to the main shaft with the longitudinal center axes of the kingpin bore holes being substantially the same orientation and preferably substantially within one degree of one another.
