    Sounds like maybe the driveline or rear dif? It happens once I reach 60mph and release/ press the gas pedal, and turns into a constant high pitched frequency at 80mph and above. Since it seems to sync with my gas pedal I assume its driveline related, any ideas?

    Lift the vehicle on jackstands, spin the wheels up to speed and listen with a stethoscope at the diff and drive-line center support bearing

    Take a sample of gear oil from the rear end and look for metal shavings.
