A/C compressor noise

I have a 2002 Taurus Sport, 3.0 24V DOHC. I noticed an irregular sound when I turned on my A/C.

VISUAL INSPECTION REVEALED: There seems to be a wheel in front of the belt drive wheel on my A/C compressor that was spinning at a different RPM than the belt. But it was intermittent. At some points it would catch up to the belt drive wheel and then slip back down to a slower RPM. The noise came while it was turning at the slower RPM.

Is this a simple fix to tighten that front wheel or does this sound like a more complex problem like a new part?

If this is not enough information, please ask questions so I can articulate the problem better.

Thanks.

Re: A/C compressor noise

How about a picture? I'd like to say that you should be able to tighten it down, but you need to inspect for collateral damage.

Ever notice that there's so many high performance parts available for GM products?

Did you ever think that maybe they NEED them?

Re: A/C compressor noise

Sounds like the hub on the front of the a/c compressor. Several way it can fail. If that's the source it would need replaced. Probably not something you would attempt at home on a 24 valve Taurus. Compressor needs to come off of vehicle to change. Without the equipment to recover and recharge ac not doable.

Re: A/C compressor noise

I captured a few seconds of video of the wheel slipping and posted it on Youtube here. Better idea of what it looks like and what it sounds like.

No bueno if I have to take this to a mechanic but you're right, I don't have the tools to goof around with pressurized lines full of chilly gas.

Here is the link:

Thank you both for your expertise.

That looks like a compressor pull.

Re: A/C compressor noise

Looks like a worn out clutch or a bad compressor clutch coil.
