1999 s80 turbocharger

[tmastbash]

I HAVE A 1999 S80 WITH 63,000 MILES. RECENTLY I HEAR A MOANING SOUND WHEN DRIVING AND ACCELERATING IN ALL GEARS. THERE IS NO SMOKE COMING FROM THE EXHAUST, THE CAR SHIFTS SMOOTHLY AND I HAVE CHECKED ALL OF THE VACUUM HOSES. DOES THIS SOUND LIKE AN EARLY TURBOCHARGER FAILURE? DOES ANYONE KNOW WHERE TO GET A REBUILT TURBOCHARGER FOR A 1999 S80. THANKS FOR ANY HELP. ALSO THE NOISE SEEMS TO BE COMING FROM THE RIGHT (PASSENGER) SIDE OF THE ENGINE.
