'92 Century clacking sound from front end at low speeds

My car, a 1992 Buick Century with a V6, is making this weird clacking noise from the front end as soon as I start it up. The car's acceleration and handling doesn't seem any different, but it almost sounds like something is rattling around in there. As soon as the car goes over 20 mph, though, the noise completely stops and everything seems fine. When I slow down again, it comes back. Any ideas as to what could be wrong? I think I might take it in to a shop tomorrow; any suggestions as to where to go? The car hasn't had any real problems; has 130,000 miles on it, and all of the fluids are checked and at the right level. I'd appreciate any help anyone would have...

Sounds like you both have a bad harmonic balancer (crank shaft pulley). I just had the same problem and replaced it. You can visually inspect the rubber portion of the pully and look for any deterioration of the rubber. Also, you can take the serpentine belt off and move the pulley with your hand. If it moves freely and hear it clacking, theres your problem.
