The steering box on a Ford F-150 is mounted on the frame. Its job is to convert the rotation of the steering column into linear motion that turns the steering linkage. The steering box uses hydraulic power to help turn the wheels. When the hydraulic seals and gears can wear down, the steering box will need to be replaced. Otherwise, steering will become increasingly difficult and possibly hazardous.
Things You’ll Need: Jack, Jack stands, Pitman arm puller, Line wrench set, Open-end wrench set, 3/8-inch ratchet and socket set, Power steering fluid
- Park the Ford on a solid surface and apply the parking brake. Lift the front of the truck using the jack and put jack stands under the frame. Locate the steering box, which is on the driver’s side of the frame. Unbolt the bolt holding the Pitman arm to the steering box using the 3/8-inch ratchet and socket.
