This is a new re-manufactured AC compressor from Ebay that has a bad compressor clutch. I believe that the re-builder forgot &/or incorrectly shimmed the clutch. Take a look at the picture below to get an idea of the the internal problem then watch the video below.
Exploded view of a Subaru AC compressor. Take note of the shim between the pulley and clutch plate.
