ABSTRACT:
An apparatus and method for preloading roller bearings which rotatably support a pinion shaft in a differential gear assembly includes a drive mechanism which selectively engages and rotatably drives the yoke of the differential gear assembly in a counterclockwise direction as viewed from the pinion shaft threaded end. A dead shaft engages the pinion shaft nut and rotates therewith. A brake is coupled to and selectively restrains or allows the dead shaft to rotate with the nut. Preventing the dead shaft and nut from rotating causes the nut to be threadingly received onto the pinion shaft and load the bearings. Disengaging the brake and allowing free rotation of the dead shaft and nut allows sensing of the bearing preload condition within the differential gear assembly housing.
