My '85 300D's A/C compressor started making some intermittent loud low pitch squeaking noises the other day but they are only noticeable at idle and only when the clutch engages. It isn't a squealing noise a loose belt would make but more like a sound a bad bearing would make without the rough growling sounds. It goes away when the engine speed is increased. Otherwise the A/C still works fine. Is there a way to lube the bearings from the outside or should I start looking for a new compressor?
