weird supercharger kinda whine??

[2001_yukon]

ive got a weird supercharger whine only when accelerating and decelerating after doing the big 3 on my truck, i was wondering if it could be the alt or something whining from producing more amps r maybe something else chime in and let me know

Typically, the alternator will not whine unless the bearing in the pulley is bad. Same thing with the AC compressor pulley. Other possibility is the power steering pump. Are you only hearing the noise on accelerating and decelerating or do you also hear it at idle ?

check your power steering . i had a whine like that before . i didnt know it was the power steering til i saw bad leaks under the truck
