First, make sure that you don't have any rocks in your hub caps.
Then make sure that there is nothing contacting the driveline.
One thing that you can do to help pinpoint where the noise is coming from is try to drive the truck right next to a wall, or concrete highway barrier. This will make it so you can tell easier where the noise is coming from.
