Abstract: An outboard sealing system cooperates with components of a heavy-duty vehicle wheel end assembly to retain lubricant in the assembly. The sealing system includes a seal that is disposed axially between an outboard bearing and a hubcap of a wheel end assembly. The seal also extends radially between an axle spindle nut and a surface of a bore formed in the hub of the wheel end assembly. The seal forms a barrier between the outboard bearing and the hubcap to reduce a flow of lubricant from a hub cavity into the hubcap. The sealing system retains lubricant in the wheel end assembly, prevents contaminants from entering the wheel end assembly, and retains the relative position of the outboard bearing in the hub during servicing. The sealing system preferably includes an additional barrier that reduces corrosion at the interface of the hubcap and an outboard face of the hub.
