An inner seal element has an inner metal case having cylindrical portion received on an outer surface of the stationary spindle and includes an annular portion extending radially outwardly from an end of the cylindrical portion and axially spaced from the first radial portion of the outer carrier case. An oil seal lip extends radially outwardly and axially from the annular portion of the inner metal case and engages the first radial portion of the outer carrier case.
