Abstract
A drive axle shaft for use in a full floating axle assembly includes a spline formed at an inner end thereof and a flange formed at an outer end thereof. A majority of the shaft body between the spline and the flange is of an increased diameter which is slightly smaller than the inner diameter of a reduced inner diameter portion of an axle housing through which the drive axle shaft extends. A pair of tapered portions form the transition between the increased diameter portion and the shaft ends to provide an axle shaft of increased torsional yield strength and torsional fatigue life.
