BEARING NOISE IN ENGINE COMPARTMENT

1999 Mercedes Benz 280 • 6 cylinder AWD Automatic • 130,000 miles

My 1999 C280 is making a noises in the front end of the engine as if a bearing is ready ready give. How can I tell where the noise is coming from and and if it is a bearing, is it a minor or major repair?

No warning lights and no work performed recently.

Remove the serpent belt and spin the pulleys by hand, they should spin freely, no binding or roughness. The ps and water pumps wont spin.
