That's why the seal is installed with the lip facing inboard. Consider which is more critical, 600W in your brakes or a little grease in the differential.

Seals are installed backwards as a pressure release as well. The manufacturer will want the excess grease / pressure to vent into the axle tube versus around the bearing seal and into the brake area. It's done often in industrial applications and confuses new guys who don't pay attention to the drawing.
