ABSTRACT:
A unitary axle seal (52) for use in an axle assembly of a motor vehicle to reduce the flow of contaminants from an exterior source (92) to an interior region (93) of the axle assembly is disclosed. The unitary axle seal (52) may be used in combination with unitized bearing seals (46) to reduce the exposure of contaminants to a bearing pack (44) contained within the axle assembly. The unitary axle seal combines a complex labyrinth (96) with an elastomeric seal (74) forming frictional sealing contacts (80,84,88) with the axle (10).
