See if you can get the old one off in one piece, and check if there are any numbers on it.

 

I feel your pain, I think it's Timken part #5206

i looked it up from the oem mopar marts source online (the same book/data base the dealer uses) and the part numbers match up which would be mopar number 4746258. Which corresponds to a national(moog) pat number 4333n that oreillys does carry. I feel like an idiot but they did have the right one it just took several people to find it.
The guy yesterday tried to tell me it was that seal but it just didnt look like it cause it had an extra dust boot on it.

hopefully this saves someone a headache later down the road.

 

Mine is also leaking from where I dropped my driveshaft. What is the seal called is it a transfer case seal? I am rebuilding my t case will the rebuild kit come with that seal?

 

Either type seal will work - with or without the extension. If you buy a transk overhaul kit, you get the one without the xt. I like the ext as it helps keep some of the dirt and water away from the actual seal surface.
