Went through this with my Dad's truck and Josh's first TB. You hear the grinding/clicking noise when doing this or that. Everyone has an idea what it is, CV joint, Hub Bearing, U-Joint etc. As said by mechanic neighbor and i agree, Sometimes it's better to let it get worse before you try and diagnose and end up shot-gunning parts. The worse it gets, the easier it will be to diagnose.
But try what JD said, it worked with Josh's first TB. Drive at a bunch of different speeds, in the range of 30-70. If the humming gets louder at any speed, try swerving back and forth, throwing the weight of the truck. If it stops while turning one way or another, probably a wheel bearing. When you take the weight off one side by swerving, the noise will usually stop, and when you throw the weight onto the bad side, the noise will get worse.
Also, you can check CV shafts, Jack up one front corner at a time and slowing spin the front wheel by hand, The bad CV might make some noises or you'll feel some chunky friction. This test might be better after the problem gets worse.
