squeaky front end

[H2duramax]

Ok so now that its cooling off in Texas a bit I decided to turn the ac off and enjoy the cool evening air... turns out having my ac on and my windows up is just enough to drown out the creaks and moans of my front end. My truck sounds terrible! Its not if I'm turning one way or the other... its if the vehicle is moving. Its an aweful noise, sounds like metal on metal. A high pitched shrill sound. I haven't been able to get under the truck yet and track it down, but I would love some insight from anybody that may know why my truck sounds like a rusted old beater with a worn out suspension.
Thanks

Ok, after climbing under the truck in the light of day I have decided the front end of this truck hasn't been greased since it left the factory... I'll take care of that today. Hopefully that solves the problem.
