Abstract
A ball joint seal is provided including an annular seal body including a first axial end and a second axial end. The first axial end acts as a dynamic seal end and includes at least one axially extending seal lip and at least one radially inwardly extending seal lip. The axially extending seal lip and the radially inwardly extending seal lip includes a channel extending therethrough that allows grease to migrate from the ball joint to the axial sealing surface of the dynamic seal. The grease that is allowed to migrate from the ball joint to the sealing surfaces of the dynamic seal help to lubricate these surfaces to improve the service life of the seal and, ultimately, the ball joint assembly.
