ac compressor

Have bearing noise from ac compressor with clutch disengaged. I assume it's the pulley bearing and dealer says there are two compressors. The FX15 has a replaceable bearing but the FS10 doesn't.

I haven't taken a look yet, but when I do, what distinguishes between an FX15 or FS10 compressor? It there a nameplate or markings?

Anyone with suggestions - make them.

Thanks
