This article applies to the Ford F-150 (1997-2008).

The Ford F-150 is a rather heavy truck, so the power steering is extremely important, and not just for comfort, but for safety as well. The power steering pump is a pressurized system, and when one of the hoses go bad and leak, air is introduced into the system, and one air bubble can ruin your whole power steering system. Although you could drive without power steering, you should be extremely careful, as it could be a hazard. Not to mention you have to be in a strong shape to turn the steering wheel from a stopping position. Instead of working a second job trying to park your F-150, read on to learn how to properly replace the power steering pump's hose yourself.

Materials Needed

  • Flare nut wrench
  • Drain pan
  • Power steering fluid

When it comes to hydraulic hard lines, like this power steering line, a regular open ended wrench will generally work. However, as the fasteners are prone to corrosion and seizing, using a flare nut wrench may be a better option, as it lessens the chance of rounding off the nut and making it almost impossible to remove. You can pick up a set of flare nut wrenches for about $20 at your local hardware store.

Step 1 – Remove hose

Before removing the power steering hose, make sure you place a drain pan under the pump, as fluid will drain out as soon as you remove the hose. If you're removing the pressure hose, you will need to use your wrench to remove the nut, and if you're removing the other hose, you will just need to slide the clamp off. Remove the line from the other side as well.

Step 2 – Install new line

Install the new line the same way the old one was installed. Simply tighten the nut on each end of the line. If you have a clamp, install the hose and then slide the clamp on to secure it.

Step 3 – Bleed power steering pump

Now that you've introduced air into your power steering pump, you need to bleed it. Fill the power steering reservoir back with fluid, then start your car and turn the steering wheel from lock to lock a dozen or so times. Check the fluid's level, then top it off. Turning the steering wheel should push the air bubbles out of the system. Drive the truck for a few miles, then check the fluid again.
