Dealing with a 2013 ford f150 electric power steering replacement can feel like a massive undertaking, but with the right approach, it is a manageable project for a dedicated DIYer.
I understand the frustration of seeing those dashboard warnings or feeling a strange shudder in your steering wheel during a turn. My goal today is to simplify this complex repair by breaking it down into logical, safety-focused steps. We will cover everything from diagnosing the failure to the final software programming that most guides overlook.
By the end of this article, you will have a clear roadmap for the entire procedure. We will discuss the tools you need, the safety precautions that protect your truck’s sensitive electronics, and the expert tips that make the job go faster. Let’s dive into the details and get your F-150 steering like new again.
Understanding the 2013 ford f150 electric power steering replacement
The 2013 F-150 uses an EPAS system rather than a traditional hydraulic pump. This means there are no hoses, no fluid, and no belt-driven pump to worry about. Instead, a high-torque electric motor is mounted directly to the steering rack to provide assistance based on input from a torque sensor.
When this motor or the internal control module fails, the entire rack usually needs to be replaced as a single unit. You cannot simply swap the motor in most cases because the internal belt and sensors are calibrated together at the factory. This makes the 2013 ford f150 electric power steering replacement a hardware-intensive task that requires both mechanical skill and a bit of computer savvy.
It is important to note that Ford issued several recalls and technical service bulletins (TSBs) regarding these racks. Before you spend money on parts, check your VIN with a local dealer to see if your truck is covered under an extended warranty or a safety recall. If not, doing the work yourself can save you over a thousand dollars in labor costs.
Why the EPAS Fails
The most common failure points in these units are water intrusion and internal hardware wear. Moisture can seep past the bellows boots, causing corrosion on the internal rack bar or shorting out the electronic control module. You might also experience a failure of the internal drive belt, which connects the electric motor to the steering gear.
Signs You Need a New Rack
Keep an eye out for a “Steering Assist Fault” message on your productivity screen. Other symptoms include a persistent “pull” to one side that an alignment cannot fix, or a “notchy” feeling when turning the wheel. If you hear a grinding noise when maneuvering in a parking lot, the internal bearings are likely failing.
Essential Tools and Safety Equipment
Before you begin the 2013 ford f150 electric power steering replacement, gather all necessary tools. Having everything on hand prevents mid-project trips to the parts store. You will need a standard set of metric sockets, but a few specific sizes are critical for the F-150 chassis.
- Metric Socket Set: Specifically 13mm, 15mm, 18mm, 21mm, and 24mm.
- Torque Wrench: Must be capable of reaching at least 150 lb-ft.
- Tie Rod End Remover: A dedicated puller or a heavy-duty pickle fork.
- OBDII Interface: Such as an OBDLink EX for the programming phase.
- FORScan Software: A laptop with FORScan installed to perform the module reset.
- Jack and Jack Stands: Rated for at least 3 tons to support the truck’s weight.
Safety is paramount when working under a heavy pickup truck. Always use high-quality jack stands and never rely on a floor jack alone. Since the EPAS system pulls significant current, you must disconnect the battery before starting. This protects the vehicle’s electrical system from shorts and prevents the airbags from accidentally deploying while you work near the steering column.
I also recommend wearing safety glasses throughout the process. Road debris and rust flakes often fall from the frame while you are loosening the large mounting bolts. A pair of mechanic’s gloves will also protect your hands from the sharp edges of the skid plates and frame rails.
Step-by-Step Removal of the Steering Rack
Start by parking the truck on a level surface and centering the steering wheel. This is a critical step for the 2013 ford f150 electric power steering replacement. Once the wheel is straight, use a seatbelt or a steering wheel holder to lock it in place. If the wheel spins freely while the rack is disconnected, you will break the clock spring, leading to an expensive secondary repair.
Loosen the front lug nuts, jack up the truck, and secure it on stands. Remove the front wheels to gain access to the outer tie rod ends. You will also need to remove any factory skid plates or plastic air air dams located under the front engine crossmember to clear a path for the rack to slide out.
Disconnecting the Tie Rods
Remove the nut holding the outer tie rod end to the steering knuckle. Use your tie rod puller to pop the joint loose. If the joint is stuck, a few sharp hits with a hammer on the side of the knuckle (not the threads) usually breaks the taper. Repeat this process on both the driver and passenger sides.
Unplugging the Electrical Connectors
The EPAS rack has two main electrical connectors located on the passenger side of the motor housing. One is a large high-voltage power lead, and the other is a smaller data connector. Carefully depress the locking tabs and pull them straight out. Inspect the truck-side harness for any signs of corrosion or melted pins while they are disconnected.
Detaching the Intermediate Shaft
Locate the bolt connecting the steering column’s intermediate shaft to the rack’s input shaft. This is usually a 13mm “pinch bolt.” Remove the bolt completely rather than just loosening it. Slide the shaft upward and off the rack. This is where your previous step of locking the steering wheel becomes vital for safety.
Installing the New Electric Steering Rack
With the old unit out, compare it to your new 2013 ford f150 electric power steering replacement part. Ensure the mounting points and electrical connectors match perfectly. If your new rack did not come with outer tie rod ends, you will need to transfer your old ones or, ideally, install new ones to ensure a fresh start for your steering geometry.
Lift the new rack into position on the crossmember. This part is much easier with a helper, as the assembly is heavy and awkward. Start the two large mounting bolts by hand to ensure they are not cross-threaded. These bolts require significant torque, so verify the threads are clean before final installation.
Once the rack is physically bolted to the frame, reconnect the intermediate shaft. Ensure the shaft is fully seated before reinstalling the pinch bolt. Tighten the pinch bolt to the manufacturer’s specification, which is typically around 22 lb-ft. This connection is the mechanical link between your hands and the tires, so do not skip the torque wrench here.
Securing the Electrical Connections
Plug the two electrical connectors back into the new rack. You should hear a distinct “click” when they seat properly. If the connectors feel loose, the locking tabs may be damaged. Use a small amount of dielectric grease on the seals (not the pins) to help keep moisture out of the connection points in the future.
Reattaching the Tie Rod Ends
Insert the outer tie rod ends back into the steering knuckles. Tighten the nuts to approximately 85 lb-ft, or follow the specific torque specs provided with your new parts. Reinstall the wheels and lower the truck to the ground. Your mechanical 2013 ford f150 electric power steering replacement is now complete, but the truck isn’t ready to drive yet.
The Critical Programming Step
The most common mistake DIYers make is assuming the job is finished once the bolts are tight. A new EPAS rack is essentially a blank computer. The Power Steering Control Module (PSCM) inside the rack needs to be told which truck it is installed in. Without this, you will likely have no power assist and a dash full of warning lights.
You have two choices: tow the truck to a dealer or use a tool like FORScan. FORScan is a powerful software that allows Ford owners to perform dealer-level diagnostics and programming. You will need to download your truck’s “As-Built” data from Ford’s website using your VIN and upload it to the new PSCM.
Alternatively, many modern replacement racks come with instructions on how to perform a “PMI” (Programmable Module Installation). If you kept your old rack connected until the last second, you might be able to pull the data from the old module and “inhale” it into the new one using your scan tool. This ensures the steering software matches your specific wheelbase and tire size.
After the programming is complete, you must perform a steering angle sensor calibration. This tells the computer exactly where the “center” of your steering is. Turn the wheel all the way to the left, then all the way to the right, and return it to the center as prompted by your software. This step is vital for the stability control system to function correctly.
Common Pitfalls and Expert Troubleshooting
One common issue after a 2013 ford f150 electric power steering replacement is a “Service Steering” light that refuses to go away. This often happens if the battery was not fully charged during the programming phase. These racks pull a lot of amperage, and if the voltage drops below 12.0V during the software flash, the process will fail.
Another pitfall is failing to get a professional alignment immediately. Even if you measured your tie rod lengths perfectly, the internal centering of the new rack will be slightly different. Driving without an alignment will cause rapid tire wear and may confuse the Electronic Stability Control (ESC), leading to unexpected braking interventions.
If you experience a vibration in the wheel after the swap, check the mounting bolts. If the rack is even slightly loose on the frame, it will create a “clunk” or a shimmy. Ensure the large 24mm nuts are torqued to the factory spec, which is usually 184 lb-ft for this specific model year. This is a very high torque value that requires a long breaker bar or a high-torque impact wrench.
Frequently Asked Questions About 2013 Ford F150 Electric Power Steering Replacement
Can I drive my F-150 with a failed EPAS?
Technically, the truck will still steer mechanically, but it will be extremely difficult to turn, especially at low speeds. It is unsafe to drive in traffic because you may not be able to react quickly enough in an emergency. It is best to have the truck towed or repaired immediately.
Do I really need to program the new rack?
Yes. The 2013 Ford F-150 uses a “smart” steering rack. Without the correct As-Built data programmed into the module, the electric motor will not activate. You might get the rack installed physically, but you will still have manual-effort steering until the software is configured.
How much does a replacement rack cost?
An OEM Ford steering rack typically costs between $900 and $1,300. High-quality aftermarket units are available for $600 to $800. While the price is high, remember that this unit includes the motor, the sensors, and the control module, which were all separate components in older hydraulic systems.
Can I rebuild my old EPAS rack?
Generally, no. The internal components are not sold separately by Ford, and the unit is factory-sealed to prevent moisture. Attempting to open the motor housing often damages the sensitive internal sensors, making the unit unserviceable for the average DIYer or even most specialty shops.
How long does the replacement take?
For an experienced DIYer with the right tools, the mechanical swap takes about 3 to 4 hours. Programming can take another 30 to 60 minutes depending on your familiarity with the software. Total time, including setup and cleanup, is usually a full Saturday afternoon.
Final Thoughts on Your Steering Repair
Completing a 2013 ford f150 electric power steering replacement is a significant achievement for any truck owner. It requires a blend of heavy-duty mechanical work and modern digital calibration. By following the steps outlined above—locking your steering wheel, torquing your bolts correctly, and ensuring the software is flashed—you can restore your truck’s handling to factory standards.
Remember that the steering system is a critical safety component. If you feel uncomfortable with the programming side of the job, you can always do the mechanical installation yourself and have the truck towed to a shop for the final software flash. This still saves you a significant amount of money while ensuring the electronic systems are perfectly calibrated.
Stay patient, work methodically, and always double-check your torque specs. Once the job is done and your F-150 is back on the road, you’ll enjoy the confidence that comes with a job well done. Stay safe and keep your truck in peak condition!
