my power steering pump produces a whining/groaning sound when the car is idling. when i turn the wheel, it really is loud. if i hold the wheel all the way to one side it is loud too. the belt doesnt appear to be really loose or really tight and it clears everything else so i dont think its rubbing. this sucks! its annoying and embarassing. what can i do. i dont want to hear that my ps pump is dead. waaaa
