\My thought was if there was metal to metal contact it may have rusted and now preventing the squeak.
When I did have an engine squeak and eventually realized it was the idler tensioning bearing. ( it grenaded the day before I was going to change it) It didn't change frequency regardless of what the engine RPM was. I was nursing it along with a few squirts of lube every few days until I could get to it. This was on my commuter vehicle.
Some times A serpentine belt will do the same regardless of engine speed. Old school, rub a soap bar on it and then start it up is a good diagnosis. Of course now they have belt dressing. When I remove a belt that is still useful and replace it with a new one I store it in my vehicle just in case. I also did that with my Polaris Ranger which is belt driven.
