Not true. There are lots of vehicles with permanently engaged hubs and selectable 4WD. No modern consumer truck sold in America has manual hubs. Do you think they're all AWD?

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.
