This is the rubbish you should not listen to.
Continue to work through the problem with the people who are helping you, as many are professional mechanics.
Yes is the same noise, trust me, its very annoying and feels like if something is trying to engage when you turn but i have it on 2wd

So even if your not moving and you turn the steering to the left or the right, you will hear the grinding noise?

If that is the case, the problem is going to be with the steering gear box or the power steering pump. But most likely the steering gear box.

If the noise happens without moving the truck, then it can not be anything to do with axles, wheel hub bearings, or tires.

Do you have the limited slip rear end? If so, did you change the oil in that? When doing so you should add two bottles of friction modifier. Often times the rear end grinding will sound like it is from the front.

No if I'm at a complete stop and then go ahead and I turn left or right at a road it will make the noise, my husband just open up the front differential but said there is no clutch there, and that everything looks brand new.

It is a rear differential that has clutches in it to limit wheel slip. As they age they chatter or grind (actually on many Fords they chatter when new too). There is an additive that needs to put in when you change the fluid or do a service. usually one bottle works, but on older and higher mileage vehicles it is good to use two bottles. If it hasn't been addressed on yours it is a good place to start. The service interval is supposed to be 30k miles.

I'm inclined to agree with alwaysfords41. You haven't answered his question (or I've missed your answer) as to wheather your vehicle has a Limited Slip differential or not.

If you can start up (very gently) while turning and there is no noise, yet when you start up with heavier throttle while turning and you get the noise, you need to add the limited slip additive to the rear differential.
