2002 GMC 2500 HD 2WD

I'm not exactly sure, but judging by the oil shot around the face of the pinion, and the puddle of oil underneath the axle housing, I either have bad bearing, and or, a bad pinion seal. I'm guessing a bad pinion seal until I get to inspecting.

Question: Does anybody have a part number/reference to a good seal?
