A wheel end assembly includes a seal for sealing the annular space between an inner member and an outer member, one of which is a static component and the other a rotatable component. The seal includes an annular case having a cylindrical portion engaged with the static component and an annular flange portion extending radially from the cylindrical portion so as to be oriented vertically with respect to the horizontal central axis. An annular seal member is attached to the flange portion of the case and has at least one sealing lip engaged with the rotatable component so as to separate the annular space into a first chamber and a second chamber. Further, at least one air vent hole extends axially through the flange portion of the case so as to fluidly connect the first chamber with the second chamber.
