Strange noise

I have a strange humming noise coming from the front of my truck that is constant with the truck speed. It is like a low whining noise. Any ideas on what it could be?

I don't have a system. It sounds mechanical, like a bearing or maybe the transmission. It whines at a constant speed and sloe=ws when the truck stops..

If it's coming from the front it could be a hub bearing.Especially if it changes with speed of truck and not engine.Also if it's 4x4 check your front diff.
