Anyone have an idea on what maybe happening here? It’s a 2021 F-150 with 60k miles.

You check the oil to see if it's low?

Yeah, oil level was good. I actually took it to ford quick lane Friday to get an oil change and have them look at it. About an hour later I got a call saying they couldn’t diagnose it and I needed to get in with the service department.

Worst case rear main seal. More than likely a crappy oil change and the residue is blowing back and catching dirt. I’d clean the area with some high pressure water and a degreaser making sure you hit as much area on top of the skid pans. Give it a few drives and see if it comes back.
I am a little concerned with the crack in your photo though?

Transfer case leak. Also is something cracked on the left side of that picture?

Good eye! I’ll be sure to point that out as well!

Crack is the stick-on insulation.

Looks like t-case RTV seal is caput. If it were a shaft seal it'd be leaking from the front or back. It's originating from the propellor output shaft area.

Looks too pronounced down the seam of transfer case to be a splatter of oil from an oil change......probably a leak thru the seal
