An axle depends from a heavy-duty vehicle. Each one of a pair of wheel end assemblies is mounted on a respective one of the ends of the axle. Each wheel end assembly includes a pair of bearings mounted on a spindle of the axle, and a wheel hub rotatably mounted on the bearings. A cavity is formed in the wheel end assembly between the bearings. A port is formed in the wheel hub and extends axially inwardly from an outboard end to a lubricant cavity of the hub, and angles radially inwardly from the outboard end to the lubricant cavity at an angle relative to an axial centerline of the hub. Lubricant for the bearings is introduced into the cavity by means of the port, and the port is tapped to receive a plug to seal it and contain the lubricant in the cavity. The port also provides a visual indicator if there is a leakage of semi-fluid grease.
