Leaking rear differential

Hey guys I'm trying to figure out what axle I have on a 2002 f350 single wheel 4x4 so I can order a replacement seal. So this morning I got to work and noticed that am oily guild was dripping from the front of my rear differential where the drive shaft hooks into it. I figure it the seal, so when I went to look up the repair kit they list several different axel options because of gearing I have no idea what axle I have as there wasn't a ln owners manual with the truck. Who can I find out what axle I have so I can buy the repair kit for it thanks. Guys.

Scroll down about 3/4 of the way down this page to find axle information for what it was manufactured with.

Check the air line that is on top of the differential to make sure it is not clogged. It prevents the differential from breathing and the pressure blows out the pinion and wheel seals.

Good luck.
