Looks like the bearings in my compressor are going bad or the a/c clutch itself is having issues. I only hear the moaning sound with the a/c turned on while driving. When you turn it off you hear a thunk, and then no noise. turn on? THUNK, and then the moaning sound starts.
In case it is no other pulley making this racket, and I have to swap out the compressor, other than OEM, what brands have you guys gone with for an install, that were good solid working and long lasting a/c compressors? It has not seized up, and I am avoiding running the A/C to keep it from doing so. I do not want to have to replace anything else caused by a seized compressor.
