Why does my steering wheel make a buzzing noise when I turn it?

Bill Griffith

When I turn my steering wheel, I hear a buzzing noise. What might be the cause?

Q. My 2001 Ford Crown Victoria has 108,000 miles on it. When I turn the steering wheel left or right, I hear a buzzing noise that can get quite loud at times. I replaced the power steering pump, and the noise is quieter but still present. What might be the cause?

A. I suspect there is air in the power steering system. You can try starting the car, removing the power steering cap, and turning the wheel left and right several times. This action should force the air out of the system. If this doesn’t work, find a shop that can attach a vacuum pump to the power steering pump.
