Abstract: An axle assembly includes a central tube and an axle spindle. The axle spindle is fixed to the central tube. The axle spindle has a tubular first section and a tubular second section extending from the first section. The second section has an outer diameter. The second section has a bearing support surface. A tubular transition section is located between the first section and the second section. An annular shoulder portion is formed in an axial end segment of the tubular transition section adjacent the second section. The shoulder portion has at least one annular profile located in the shoulder portion between the annular shoulder surface and the bearing support surface. The annular profile is defined by a surface with a diameter not less than the outer diameter of the second section. An antilock braking system sensor bracket locator nub is integrally formed in the tubular transition section.

Abstract: A mounting assembly for mounting a wheel end sensor in a heavy-duty vehicle hubcap that includes at least one adhesive disposed between the wheel end sensor, hubcap, and/or components of the wheel end sensor mounting assembly to prevent aqueous road contaminants from entering the wheel end assembly and prevent lubricants from exiting the wheel end assembly during operation of the vehicle. According to one aspect of the wheel end sensor mounting assembly, the adhesive is delivered via one or more gaskets formed of a hydrophobic or non-wicking material. The one or more gaskets are disposed between the wheel end sensor, the hubcap, and/or components of the wheel end sensor mounting assembly. The one or more gaskets and the adhesives provide sealing interfaces between the components.
