Keep the rear wheel hub torqued down and secure with the Beck/Arnley Axle Nut 103-0512 (also written 1030512). This rear-position axle nut threads onto the axle shaft to retain the hub and bearing assembly and hold the setup together as designed. It's application-specific and drops in as a direct replacement for the listed foreign-nameplate applications.

  • Direct OE replacement: Engineered to match the form, fit, and function of the Original Equipment part across foreign nameplates.
  • Rear position: Cataloged for the rear axle/hub location on the applications below.
  • Application specific: Sized for the exact vehicle it's listed under, so it installs like the factory nut.
  • Sourced to Beck/Arnley standards: Built through a global sourcing network to meet Beck/Arnley requirements and specifications.

Signs the original axle nut may need replacing include damaged or rounded flats, stripped or galled threads, or a nut that no longer holds torque. Always confirm compatibility by your vehicle's year, make, model, position, and drivetrain configuration before ordering, and consult the service information for the correct torque procedure.
