Constant moaning coming from the drivetrain...
It is hard to describe a noise, but I will do my best...
The noise is a dull moaning, that kind of sounds like mudding tires driving down the highway.
It starts relatively quietly at about 15 mph, and gets noisier as the speed increases.
The alignment is pretty bad, because if you let go of the steering wheel the truck will pull hard to the right. If you let go of the wheel when driving straight the noise gets quieter, however you can't do this unless the road slightly turns to the right. If you go around a more aggressive turn to the right the noise gets even quieter, but it never goes away totally. If you turn to the left the noise gets louder so it has something to do with the alignment I believe.
Now onto the brakes...They seem to have a 5/16" of pad left, so I don't think it would be the pads. I do think it has something to do with the brakes, because if I use light braking nothing changes, but if you add moderate pressure the noise goes away. I don't know if it has to do with the clamping force of the pads on the rotors, or if it has to do with the weight transfer onto the front suspension???
You guys have any ideas as to what might be creating the moaning?

As for the noise, since it changes during turns ect I would guess tires but like you said it needs an alignment. Next would be wheel bearings/hubs. Next if it is a 4wd (You didn't say) it may be the CV joints.
Some brake pads have a squeaker or what ever it is called to make noise when the pads get low to indicate to change them. This can be your noise maker since it stops with hard braking.

I see where you are coming from with the wheel bearings, because that is what it sounds like to me, but the noise should get worse under hard turning and braking due to increased load on the bearings. I also cleaned and repacked them about 2 months ago, and they looked brand new after I cleaned them. The tires are standard road tires, nothing aggressive or knobby, so I wouldn't think it would be them. They are getting low on tread so I will get an alignment when I replace them.
