Spindle nut

A spindle nut assembly (50) is presented comprising the following three components: a washer (60), a locking snap ring (80), and a nut (70). Each of these three components function together, and in conjunction with the spindle of a vehicle axle, to affix a wheel hub assembly onto the spindle of an axle. The three components comprising the spindle nut assembly incorporate design features allowing the components to interlock and resist loss of preload compression on the hub assembly.
