99 TA: It's been sounding like a worn pulley bearing. I can't pinpoint the noise exactley but my best guess after getting under it is that it's coming from the crank pulley or harmonic balancer? The noise is constant and does vary slighty with rpm. Any suggestions would be helpful.

 

More than likely one of your tensioners. They're cheap and easy to replace.

 

yeah, its most likely the tensioner. I had the same problem, thats what it was. Should be covered under warranty if you have one.
