Abstract
An axle spindle and wheel end assembly includes a precision-formed axle spindle, wheel hub, and axle spindle nut. The axle spindle is formed with parallel inboard and outboard bearing surfaces, a shoulder that is perpendicular to the inboard and outboard bearing surfaces, and threads for a spindle nut that are aligned with the inboard and outboard bearing surfaces. The wheel hub is formed with inboard and outboard bearing surfaces that are in parallel alignment with one another, and bearing axial stop surfaces that are perpendicular to the wheel hub bearing surfaces. The spindle nut is formed with threads on its inner periphery and a flat inboard surface that is perpendicular to the threads. The axle spindle, wheel hub, and spindle nut cooperate to enable an axle spindle nut assembly to consistently provide a light preload on a bearing cone and spacer group of the wheel end assembly.
