I here a humming noise in the front of the truck. It sounds like a hub bearing but I dont know for sure it could be some kind of other problem steering, vacuum hose, maybe the 4 wheel drive. Would some one please help me so I can get it taken care of before winter.

There is a tool you might be able to borrow or rent from an auto parts store that borrows them called the "Chassis Ear". It is a set of six microphones, a switch box, and headphones. You clip the microphones to suspect points, then drive around while listening with the headphones. You can move the microphones around to zero in on the source of the noise. Be aware that many mechanics have never seen or even heard of this tool. Suspension and alignment mechanics use it to find rattles, squeaks, and other noises.
