Yesterday I was driving and stopped at a light. I started moving when the light turned, all of a sudden I hear a loud noise, I thought someone on a bike was following me then I realized it was me. I stopped the car at a mechanic I know just down the street he looked on the bottom but nothing was hanging down. i did not have time to put it on lift, so I had to go( the car runs well) My question is this "if everything is attached on the bottom why is that noise coming? Is it a hole? If it is a hole can i patch it? I will look Saturday (right it is freezing outside but will be much warmer this weekend
