2000 Taurus Load roaring noise in front
I have a 2000 Ford Taurus with 67,000 miles on it. When I get up to about 25 to 30 mph a load roaring noise begins. The faster I go, the faster and louder the noise gets. I thought it was just loud tires, but some people that have rode with me think it could be something else. If I shift it into neutral while going 50 mph, the sound remains constant. It only drops when the speed of the car drops. Is their something I could do to first of all make sure it isn't the tires? What if I jacked up the car's front end and then ran it up to 45 mph or so with the wheels off the ground? If the sound is there, then I would know for sure that it wasn't my tires. I don't know what to do. I hesitate to take it in for diagnostic work as then I am $100 in just to hook it up to the computer. Any help/ideas would be greatly appreciated.
