could be lots of things, you might try recording a video of the sound as best you can and then upload it to youtube and post a link to the video here.
youtube is free to post video's on
preferable to make a video longer than a few seconds, if you only hear it at a certain speed try recording (all one video) before that speed, then while at the speed, then above that speed and back down to that speed again until you fully stop

Its a very low level growling..... I called mechanic friend, he says it could be the hub bearing??

Put the truck on a lift, and get the wheels in the air. Have 1 person in the truck and put it in gear and accelerate to the speed where the noise occurs. Then, a second person with a stethoscope goes under the truck and listens along the drivetrain and finds the source of the noise.
