My clutch bearings have started making a bunch of noise as well. At least it sounds like it's coming from there. It may be the belt tensioner. Anyway you can buy the bearing for $17 but it takes a special tool to get at it. Our mechanic in our club told me he has never been able to get the pulley off without destroying it. He always ends up replacing the whole compressor. I found remans from $160ish a lot of places so I will probably end up doing that. Better than $330+ for new.

Suck you can't just replace the bearings.
