The nut including a flange which provides inboard retention and restrains inboard movement of the wheel bearing relative to the live spindle. The nut also includes a surface which at least partially defines the bearing seat for the wheel bearing. The retaining nut is engaged by a locking assembly mounted to the spindle's inboard end so as to prevent disengagement of the retainer nut from the spindle.
