I have a 95' Pathfinder SE. About a week ago I started hearing a very loud high pitched whistle from the A/C compressor. I tried hitting either side of the clutch with a little WD40, which quieted it a bit but didn't fix it. I am guessing the bearing is going? Does anyone know if the compressor can be rebuilt without disconnecting it from the car (and R134A) lines? Any other quick fix ideas (like is a lube point that I can't see)?
