Aluminum is now being used as a differential housing material to reduce vehicle weight and improve fuel economy. Since its use is not yet fully recognized, several considerations should be made when putting it into use. Bearings may need to be sized larger to provide adequate life over a wider range of operating preloads. Interference fits between the bearing outer races and housing must be greater to provide support for the nearing even at high operating temperature. Preload targets may need to be larger to account for the lower strength of aluminum. Setting bearing preload precisely at axle assembly may be necessary to obtain adequate life.
