A/C compressor rattle.
 

My 82 c10 still has the original r12 compressor and it works, however it's been making a rattle noise that sounds like the bearings are going out. Are these bearings on the clutch or part of the compressor? Any fixes other than replacing the compressor?

Where can I buy a replacement compressor that's not used?

Thanks

The older long cylindrical compressors can have both the front bearings and clutch replaced. IIRC - without breaking the refrigerant seal. Not sure about the later pancake compressors.

I just ordered a new R4 compressor for my 82. $235 on Rockauto. New by four seasons.

Sweet, that's not bad. So I'm guessing I'll need the receiver dryer also and some r12 compatible refrigerant?

I'll do some more research to see if I can swap the bearing first.
