1996 Pontiac Grand Prix SE noise

Picked up a great running SE and it sounds like a bearing is going out on maybe the harmonic balancer? If this even sounds right. The idler pulley was replaced and serpentine belt about 32k ago. It is not the power steering pump I believe. It steers great and is not using any fluid. Any suggestions or ideas? Thanks all in advance.

Figured out it was the A/C compressor. Will pick up one up at a junkyard tomorrow for $40. Would not be so bad to go without the A/C but no way to get a different belt on it and bypass it. But the noise is bad enuf to get me to change it out. Anybody have an idea on how to charge the system with refrigerant?

Swapped out the A/C compressor for $40 and its done. No noise and quiet as a church mouse. Will post pics later. Thinking I did ok on this one. Just need to have the system charged with refrigerant now. Was going to do it myself but figure I will let a shop do it.
