Pully Wobble Problems? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a C20 with a 327 AC/ALT/PS Pulley system that seems to have a little play or whobble. On a red light idle I sometime hear the tink tink of the fan touching something.

I just replaced the water pump and fan clutch about a month ago. Recently threw the AC belt (from the whobble?)

Can anyone help me troubleshoot the cause or direct problem of this? Is it possible that the water pump shaft is already spunked or is a little movement here normal?
