So I was about to make a left turn and got into the lane upon stopping I hear what sounded like a loud clunk. When it was my time to go I started hearing a metal to metal sound the more I accelerated the more the sound got loud and continued. I stopped the car to see if it would do it at idle but it did not. Now I got home and when I reversed to park another clunk and then the noise went away for a moment. I can still hear a very faint metal to metal sound.... any ideas? any clues where to look or start looking... thanks.
