Hello everyone
I've came upon this strange whining noise lately from my car, I have checked that when turning the wheels it wont cause further whining noise , so i assume it wont be the power steering pump's issue? The noise seems came from pulley/belts (But I'm not sure), also i checked on internet will that be possible caused by alternator?
Thanks !

Change your idler pulleys immediately. That's a failed bearing ready to grenade soon.
