An axle assembly for a motor vehicle of the type including a rigid drive axle and a rigid axle tube extending between a drive axle differential to the axle wheel end. The axle tube features a radial flange defining an outboard facing bearing retention shoulder. A bearing carrier unit is bolted onto the axle tube flange to trap the bearing outer race. The axle shaft engages the bearing inner race which is trapped between a flange on the axle shaft and a nut threaded onto the axle. This wheel and system provides improved wheel run-out characteristics which are advantageous for disk brake applications and facilitates the use of anti-lock braking system wheel speed sensors.
