Pinion seal. Also check for play in the bearing, same name, pinion bearing.

yeah that seal is called the pinion seal. the axle seals are the seals on the side of the axle at the edge of it just behind the backing plates

When you replace the seal tighten the nut to 12-15 Inch pounds torque rotation with the hubs off. No more than 15 Inch pounds.
