Q: How to remove and install a steering gear on Ford F-150?
A: To conduct hydraulic assist steering, park the vehicle straight, loosen lug nuts, raise the front end, and remove the wheels and skid plate. Mark the relationship of the lower steering shaft U-joint to the rack and pinion input shaft and remove the U-joint. Remove the oil drip tray, disconnect the pressure and return lines, discarding O-rings. Disconnect the tie-rod ends. On 2008 and earlier models, remove the rack and pinion bracket fasteners and brackets. For 2009 and later models, it's bolted directly to the crossmember. Remove the rack and pinion assembly via the left wheel well. Install by aligning match marks, tightening all fasteners, using new O-rings for pressure and return lines. Refill and bleed the power steering fluid. For 2011 and later models with electronic power assist steering, reprogramming via a proprietary scan tool is required.
