What is the correct part number for the rear axle shaft seal on a 2009 Ex?

[1995 Explorer]

I discovered the other day that the rear axle shaft seal on my 2009 Explorer appears to be leaking on the passenger side. I was looking at the Rockauto Catalog and there are two parts listed and they appear to be a slightly different design. How do I know which seal is the correct one? Would anyone who has done this job before care to shed some light?

I have worked extensively on 2nd generation explorers, but this is my first time working on a 4th gen.

go here http://www.fordparts.com/ Do a part search using your VIN and find the correct seal then take the Ford part number back to rock autos website and cross reference the parts your looking at with the Ford part number! Then you will have the correct part for your Explorer.
