A/C Noise

The a/c clutch on my car is making noise like a bearing going out. If I spray it with water it momentarily relieves the noise. Can I replace the clutch only, or do I have to replace the whole unit? This vehicle is a '97. Do I need to buy a new clutch or do you think it's safe to ebay a whole assembly then remove the clutch? Is the clutch easily removed without loss of freon while still on car? Do I have to have a special tool to remove the clutch?
A lot of questions so any help would be appreciated.

Your local parts place should have a clutch and hub for it.
Yes you can change clutch and bearing with lose of gas.
But you will need a couple of removal and install tools.
Which some parts places like auto zone will rent or loan.

Thanks for the reply. I'll be tackling this job real soon. Ill probably be going with a new replacement part.
