Only while in drive, a rubbing squeak has developed up to @ 20 MPH. It sounds like it is coming from the drivetrain/driveshaft while I walk beside the truck with my wife driving. Once put in neutral and is coasting the noise ceases. Other than the annoying noise the truck runs well with no mechanical transmission/drivetrain issues. Thank you.

Does it vibrate at higher speeds? Sounds like you have a dry U-Joint. If it's already squeaking, you better just have it replaced. The damage has probably already been done. Lubricating it may shut it up temporarily but not for long. To check them, first block the wheels, set the parking brake, and remove the drive shaft. Move the u-joints by hand. You'll probably feel a tight spot, or even hear the squeak. The reason the noise goes away when you put it in neutral is the load is taken off the drivetrain.
