Is the belt good? Is there a tensioner on the motor to keep it tight? Is tension of the belt provided by adjustment to something like the alternator? Tensioners on late model vehicles is provided via a spring loaded system with a pully attached about three inches in diameter. The bearing does go out which will cause a noise. Check it if your vehicle is so equipped. With the belt off, if the tensioner wiggles back and fourth from back to front it's shot.
