How to Troubleshoot and Replace a Power Steering Pump on a Ford F150?

If you have been diagnosing your Ford F150 and find out that the steering slows down in power decline mode or produces a whining sound when steering, then it is about time you check your Ford F150 for power steering pump problems and replacement. 

Below is the procedure for diagnosing and fixing your truck’s power steering pump. Osias offers solutions for Ford F150 power steering pump troubleshooting efficiently. 

Troubleshooting the Power Steering System

To proceed to replacement, once necessary, a thorough check-up of the system must be done. 

Here is how to diagnose the problem:

  • Check U-joints in the steering shaft

The U-joints may be the cause of the problem if your steering feels hard or stiff, but you do not hear any noise. The problem could be addressed when a lot of WD40 or any other lubrication is applied.

  • Check for whining noises

When rotating, a loud “whining” sound usually means that the pump is broken or that there is not enough fluid. Verify the reservoir’s fluid level first. Fill it if it is low, and if necessary, flush the system.

  • Examine power steering lines

Inspect the high-pressure and return lines for leaks. A leak in the lines can damage the pump if not fixed.

  • Consider the rack and pinion

If the steering wheel does not return to the centre, then it might indicate a faulty rack and pinion. If the pump does not create normal fluid pressure, then the pump needs to be replaced.

Replacing the Power Steering Pump

Here is how to accomplish it:

Tools Needed:

  • Pulley puller tool
  • Cooling fan removal wrench set
  • ½” breaker bar or serpentine belt tool
  • Various wrenches (10mm, 14mm, 16mm, etc.)
  • Drain pan, time, patience, and a bit of beer for fun!
  • Prepare the Truck

Raise the truck and use stands to support it. To avoid debris entering it, remove the air intake system and cover the throttle body. In order to get to the power steering pump, the fan and fan shroud must be removed.

  • Remove the Serpentine Belt

Take off the serpentine belt using the breaker bar.

  • Drain Fluid

Place a drain pan underneath and remove the fluid supply line from the pump to drain the old fluid.

  • Remove the Pump Pulley

Use a pulley puller to remove the pulley from the pump.

  • Disconnect the Lines

Unbolt the pressure lines and remove the bolts securing the pump to the bracket.

  • Install New Pump

Install the new pump in reverse order. Ensure you carefully install the O-rings and Teflon seals on the hoses.

  • Install Pulley and Reassemble

Use the pulley tool to attach the pulley to the new pump. Reassemble the fan shroud, serpentine belt, and air intake system.

  • Flush and Refill the Fluid

Replace the ATF fluid in the system, check for leaks, and purge the air by repeatedly twisting the steering wheel from lock to lock.

Once these procedures are finished, check the fluid levels, look for leaks again, and experience dependable, smooth steering once more!
