Easiest way to find out if it's drive line or chassis is to take the axle shafts out and run the drivetrain up to where the vibration occurs. Easiest and quickest way to know if it's chassis or driveline.

I've never gone to that extreme, but in one particular case, I have taken all tires off to 'prove' to someone the problem was in driveline, and not beyond (tires).

Try this,to check your rear suspension busings.When your bobtail and parked.chalk your tires,release your tractor brakes.stand between the drive axles and try to rock the truck back and forth.watch your suspension bushings for any play in them.
