What? Why? When you go around a corner, your tires turn at different speeds which is where the diffs come in. What would make a transfer case need to act as a diff?

I looked up the specs for the 1994 F-150 and it was available without manual hubs. I guarantee they didn't use an AWD tcase, but most likely the same part time 4WD one you have.
On a vehicle like my Jeep without manual hubs, if you shift the tcase lever to 2WD mode, it disconnects the front driveshaft from the transmission. But the front wheels are still attached to the axles, the differential, and the driveshaft, so all those parts get turned by the road moving past the car.

Like stated above, if you dont have a manual locking hub, chances are they are then automatic locking hubs which means only the wheels are turning when in 2wd.
