Another vote for power steering. I know nothing regarding more modern Fords but we have had a collection of clunkers over the years and they all whined if you turned the wheels when the truck was stationary/moving very slowly. They needed fixing when the steering wheel started to jerk/ not turn smoothly, usually belt tightening. Never had one fail/lose fluid, but keep moving and you can steer, won't be easy, not at all, but a strong arm can get it done.
Could be the hose has a leak, or the PS motor needs to be changed, or there is a little radiator thingie for the PS motor that could be bad. When that went out on me I have NO steering and was very glad I was not hauling at the time because the wheel practically locked up and I had to stop.
Flip the hood and check the fluid level and go from there.
Narrow the search by noting the noise and what changes its pitch, volume, etc.
Then isolate the cause. Is the noise only present when truck is moving? On a clear road, put the truck in neutral and coast. Does the noise change when you rev the engine while coasting? If yes then, the cause is likely engine related. Alternator bearings, water pump, a/c, cooling fan, belt tensioner, etc as the power steering pump could be the culprit.
As best I recall (truck does not leave the farm too often) I hear it when I first start up, then sometimes when truck is moving, but not constant.
This truck is new to me - I got it in March - but it had gotten a lot of use from former owner who used it to haul 2H GN w/LQ on camping trips several times a year.
Her husband is a longhaul trucker with his own garage/shop, so it was kept in good shape. He insisted on replacing brakes before delivering the truck to me.
I will be driving it tomorrow (sans trailer) so will make note of when the noise does & does not happen.

Does the noise worsen if you turn the wheel while in park? It may have something to do with the power steering. If not, well...??
I agree with everyone who said power steering. Did you check the fluid levels? Very often it's a sign of low fluid levels... so you then need to find out WHY you have low fluid levels.
I had to get my steering column replaced for a leak I had (could have kept going as it wasn't a fast leak, but why risk it?) and was lucky to have a friend who could replace it for me. I think the parts were $250 and the estimates from mechanics were around $800.
My horse is a dressage diva so I don't have to be.
