My AC Pulley has started to make a pretty loud rthymic squeaking noise.. Does the pulley/bearings just need to be replaced? Or is there more involved in it? Looked at old threads .. Didn't really find just a specific thread on just the pulley making noise. I was going to attached an mp3 file of the noise but it looks like that format is not allowed?? WTF is up with that?
Sounds like you are referring to the ac compressor clutch if it’s making a significant noise you’d wanna replace that so it doesn’t lock up and throw a belt
OK so besides taking the belt off and spinning each one/pulley individually. What is the best way to tell which of those pulleys is making the noise? From what i can tell the squawk is coming from the AC compressor side of the engine..
I use a wooden yardstick and put one end on the part I want to listen to, then put the other end on my thumb and that against the front of my ear. Put a very slight bow in the yardstick and noises will then transfer up so you can listen. A good bearing will sound smooth and bad bearings will have a rumble as you listen.
