The power steering system in a Ford F-150 pickup is a hydraulic system, which ceases to function correctly when it can't maintain pressure. If a leak forms in a power steering line, the power steering pump can't build up the proper amount of pressure to turn the wheels, and your steering loses its power assist. Although you can still drive the truck, it's best to replace the line as soon as possible. In this case, the project vehicle is a 2005 Ford F-150, but the process is similar for other vehicles as well.

Step 1

Use the jack to lift up the front of the vehicle, then set it on the jack stands. Be sure that the vehicle is completely and solidly on the stands prior to working on the vehicle. Locate the power steering pump on the driver's side of the engine, and set the drain pan underneath it.

Step 2

Locate the power steering line you want to replace. If the old one is leaking, then it likely will have power steering fluid all over the line so it should be easy to locate. Loosen the line from the steering rack using the line wrench and allow any excess fluid to flow into the drain pan. Then remove the fitting all the way.

Step 3

Trace the line to its connection on the power steering pump. Loosen the fitting with a line wrench, then remove the line from the truck. Install the replacement line in its place, using the line wrench to tighten both fittings.

Step 4

Open the power steering pump fluid reservoir cap with your hands and fill it with power steering fluid. Then take the truck off of the jack stands with the jack.
