Hello, I'm getting this noise on retractions: https://www.youtube.com/watch?v=rmdWcJdKziI

I don't know if it's the extruder gears or the motor doing that, and it's bugging me. Lowering retraction speed to 36mm/s and below fixes it, but I would like to know what's going on anyway. I upgraded my drivers to TMC2208s and all other axes are fine. Vref I believe is 1.31V on the extruder driver, 0.8 all the others.

Also, that's a genuine titan extruder.

Should mention I'm not a stepper driver or motor expert, at all.

EDIT: The extruder had never been installed correctly since it was clicking due to barely noticeable backlash, this is NOT a noise I'm only noticing after replacing the drivers. Retracting 5mm/s slower makes it pretty much dead silent, but otherwise this noise also makes the whole printer vibrate. This doesn't feel or seem right. I have already lowered vref to 0.9V

EDIT 2: This happens without any filament as well.

EDIT 3: Running the motor without extruder attached does not make any noise, therefore the problem is definitely in the extruder. Don't know if it's a limitation of geared extruders or the titan extruder in general, or if I just assembled something wrong, or even worse if some bearings are damaged.
