My windshield cracked back in October or November and after much prodding my dealer eventually agreed to replace it without charge. But now my replacement windshield makes a clicking noise when traveling on not so smooth roads. The windshield guy has attempted to fix it twice but can't figure it out. Anybody out there know what the problem might be?

Are you sure it is your winshield and not your dash? There is a service bulletin about the dash noise perhaps you should check that.
