Since its happening during decel and engine braking, it may be the PO rode it like a wuss (aka like me), and it may not have ever been used. Kind of like the little old lady and the 4 barrel carb. It may need need some actuating and maybe an oil change and may come back on its own.
Other things to check would be the drive belt pulley, as when the wheel is driving the engine, its putting extra load on the pulley, and perhaps the rear wheel bearings.
