    There is a very strange tapping noise coming from what sounds like the rear end. It only happens when I'm slowing coming to a stop. It happens before I apply the brakes, I can only hear it after I take my foot off the gas. Its really fast almost like morse code. LOL. I thought it was a broken exhaust hanger but that wasn't it.

    Any help is appreciated!

    Thanks for the help. Is that an expensive repair? Also is it something that should be addressed soon?
