A wheel hub assembly includes a mounting base and a wheel hub supported for rotation on the mounting base by a plurality of bearings disposed within an annular space between the hub and base. A sealing system is provided that seals all points of intrusion into the space such that liquid contaminants are inhibited or precluded from entering the space and reaching the bearings when the assembly is subjected to an immersion/thermal shock test in which the assembly is heated to an elevated temperature and then immersed on a cold bath of the liquid contaminant. A method of testing the sealing integrity of wheel hub assemblies is also provided.
