Grease retainer for vehicle wheel hubs

摘要

A wheel hub assembly includes a first bearing assembly, a wheel hub, a grease retainer, and a second bearing assembly mounted on a spindle. The grease retainer extends between and in engagement with the first bearing cup, and the second bearing cup. The grease retainer is formed of a resilient material, to maintain the retainer against the bearing cups such that the required grease fill is reduced and prevents grease from escaping the bearing assemblies.
