Have an 04 Durango with 4.7.liter engine. Vehicle just started making what I would describe as almost like a metal on metal rubbing or light grinding noise but not very severe and it seems to be coming from what I think is the a/c condenser or compressor located to the left of the alternator. It has a pulley on it and was just wondering whatever this part is does the pulley for it have a bearing in it? I'm not sure what that part is but that's where the noise is coming from. just wondering if anyone has any ideas? Any suggestions on what I could do to maybe pinpoint the problem? As always thanks for any and all help.

 

It is the A/C clutch.

If you look into the bearing most places like Auto Zone have it. Could also the clutch pads worn out and needing replacement.

 

Forgot to mention that the noise is more noticeable when you accelerate and less when you're off the gas. Still think it's the A/C clutch bearing or could it be the idler pulley?
