I am getting a scrapping noise from my engine, i have tracked the noise down to what i belive is my power steering compressor (the accessory belt connects tot he top of it) i put my hand on it while engine is running and there is a good amount of vibration comming from it (more than the engine)
so i am pretty sure this is my problem, I put oil on it and it quieted down but is still making noises and clicking sounds.
any idea what this is, and how much it costs to replace it?

(my belts are in good condition also)
