Patent attributes
An axle spindle nut assembly secures a wheel end assembly on an axle spindle. The wheel end assembly includes outboard and inboard outboard bearings that are immovably mounted on the axle spindle, and a wheel hub which is rotatably mounting on the bearings. The spindle nut assembly includes a nut that threads onto an outboard end of the axle spindle, and is tightened against the outboard bearing to a selected torque level. The nut includes an outboard surface that is formed with a plurality of features. A washer is formed with a tab that engages a keyway of the axle spindle outboardly of the nut, and with a plurality of mating features that mechanically engage the features formed in the outboard surface of the nut to prevent substantial rotation of the nut after the nut has been tightened to the selected torque level.
