Please help!!! I have an 05 F-250 and have had the truck for 6 years and had never had power steering. I purchased The truck with it already lifted . The truck has a 6" lift on 37's. I have changed the power steering pump with a motorcraft oem pump, red head gear box, new hydro booster. The truck will turn great in grass or gravel while not moving or if you are driving the truck turns fine. I have removed the steering stabilizer and put stock tires on still no power steering. Any help or ideas would be great.
