A pinion shaft assembly facilitates assembly of an automotive differential. An angular contact double row ball bearing is assembled to an outer surface of a hollow pinion shaft. An axial pre-load is established and maintained by orbitally forming an outwardly turned portion of the hollow pinion shaft. In some embodiments, the two inner rings are assembled to the pinion shaft. In other embodiments, a raceway may be formed directly on an outer surface of the pinion shaft to eliminate one of the inner rings. The pinion shaft includes a spline, such as an axial spline or a face spline, for fixation to a driveshaft.
