Hello,

I have been experiencing major belt vibrations and noise. I am in the process of replacing the shock and tensioner spring (again) and I'm going to replace the pulley on the alternator. Ever since I have owned the car, the AC compressor clutch has been very noisy when it turns on, or when it switches between low and high pressure...it almost sounds like a machine gun, sometimes clicking fast, other times clicking slow. The system blows cold air and builds correct pressure so I am quite sure it is just the clutch. Does anyone have any experience swapping out just the clutch and not the entire compressor unit on this car? Is there anything I need to know before attempting to do so? Thank you.
