Weird whining from supercharger

[Timing]

Recently i started hearing my supercharger making a weird wind down noise after i really hammer on it and let off that i dont think it ever made befor. Then yesterday i started hearing a slight sound when slightly pressing throttle like my electric throttle is winding or its my s/c i cant really tell if they are linked and my s/c bearing or coupler is going or what.If that makes any sense. I do know that my alternator seems to be making a chirping sound as if thats going but i tested it out and im getting great voltage from it.

Its really hard to tell cus one i cant throttle it from under the hood and i had my gf press the throttle for me but its really hard to hear over the engine but i can hear it clearly from inside the car

Get a long screw driver, place it in different spots and then put your ear up to it.

Needle bearings or the snout bearing. Check the fluid if low fill might shut it up for a little while
