Properly I did discover out what the primary problem was with the thumping noise with my 2000 Taurus. I really feel actually stupid as the main drawback was truly one of the lug nuts not being tightened down on one bolt. Apparently when I bought my tires (new) well over a month ago they did not appropriately tighten down one lug nut on the front left wheel. I did check with my hand previously and did not really feel any free lug nuts, however this time with the automobile jacked up and going over with a wrench – the one bolt was not tightened all the way in which. There is still a really slight noise coming from the same area – however it is barely noticeable.

The day I took the car in to have the wheel bearing mounted, before they mounted it, I drove it 20 miles at 70 mph and it didn’t vibrate in any respect when I hit the brakes, but the wheel bearing noise was very loud.

The pc registers a specific hassle code to indicate which sensor reported the problem. These codes are often known as the OBD I and OBD II codes, but extra on that in a moment.
