Rear Axle Diff Seal

Hi,

Anyone know what the exact part number is for the seal for the rear axle in a 2003 F150 4x4 ?? Mine decided to leak yesterday and so I looked up Ford for the part but there's two .. one is thick and one is not.

I don't want to take the seal out first to look because I got no other vehicle to get it and putting it back in and out would be silly.

Any help in locating the right part would be nice thanks!

There is a lighter duty axle, 8.8 inch and a heavier axle 9.75 inch. The lager axle was used in ALL Crew Cabs. Im not sure about the FX4- short bed..
You can look at the rear axle cover design, rear axle code tag, or drivers door tag to get the axle code and know which one you have. I assume that is the two different sizes.
