It looks like that sound was not coming form under the hood but from it sounds like from the tires.....I had a friend tell me that it could be one of a few things 1, brake sensor 2, bad wheel bearing 3, somthing in the driveshaft. Anyone have aby input on this issue. Thanks (If you guys did no read the other form the problem I am having is a clicking sound that seems to follow the speed of the tires meaning when I drive faster the sound speeds up and when I drive slower the sound slows down, and this is for a 1997 Towncar with 64,000 miles on it) Thanks for your help guys.
