My guess would be the steering box or the King Pins. Have the king pins been greased lately? Jack up the front wheels off the ground, get someone to turn the wheels while you go under & pin point where the noise is from.
Check the rotor shield (plate) on that side. You might of hit something and slightly bent it. When you turn left, a small amount of force might be just enough for the rotor to rub on that sheild. If that's the case, just bend it back.
Could be something else but check that first.
Try greasing the kingpins. The best way is to put the tires on cardboard and have someone turn the wheel lock to lock as you pump grease into the zerks.
Before you pack the bearings, did you check everything else everybody mentioned in here? I doubt it the bearings because the noise would be there all the time, not when you're just turning. But, if it is the bearings, you need to replace them & the races. If they re grinding, they're shot; grease won't help.
Buy yourself a HAYNES Techbook and you'll find all the how to in there. Or find yourself a friend that knows how to teach you.

The noise would get louder though, because you are putting more force on the bearing when you turn than you are going straight.
Then of course there is an inner and outer bearing on each side, and only one may be going bad.
It could also be a misaligned brake pad, or a worn out one too, as a guess.
This is also assuming that the truck is moving forward or rearward at the same time you are turning....

N7ghtwolf:
The wheel bearings should be packed around the same interval as when you change your brake pads. Or anythime the wheel bearings become loose.
Hence the test I mentioned earlier, about grabbing the wheel at the 12 and 6'oclock positions,and check for play.
When you do repack your wheel bearings, it would be a good idea to do your brake pads, and machine the rotor if it needs it at the same time, because everything is apart anyway.
If you don't feel comfortable doing it yourself, you can take it to a reputable Tire Shop, and have them do it for you as well.
just my two cents.
