That sound is aggravating. Every sound of friction causes you to clinch.
If anyone drives on a road where there is a wall on your right, or little traffic, you will hear it. Pull up to a stop, and it goes away. Rev the engine, and you do not hear it. So, to us semi-mechanics, who have lost all our tools we used on our 1960's model cars, we use our ears as well as our eyes (noses too).
