1999 Ford F-150 mileage: 89,000. My question is due to a humming or whining noise as I accelerate. Once I get to about 40 mph, I begin to hear what sounds like a loud humming from my tires. It almost sounds like the noise as if I had big tires on the truck. The tires are of normal size. As I decelerate, the noise winds down. Will the pilot bearing or throw out bearing cause this? I checked the wheel bearings, and they are fine. Also, when I push in the clutch, the noise seems to disappear. I realize without driving the vehicle it is hard to make an assumption. Any advice would be helpful.
