It's the bearing on the freewheel pulley that is a little noisy, not the compressor. I got the rusty center nut off of the practice R4 from the 300DT (with a bad solenoid coil) with Freeall penetrating oil, 3/8 breaker bar, 14 mm socket and impacted it off with a rubber mallet. I am going to Autozone and see if they have a puller that will fit. Hope the bearing in there is standard off the shelf.
