Recognizing the Signs of a Failing Wheel Bearing on Your F-150
Before you dive into a repair, knowing what to listen and feel for is crucial. A failing wheel bearing often gives several warning signs that can help you pinpoint the issue early.
Ignoring these symptoms can lead to more significant problems, including damage to other suspension components or even wheel separation in extreme cases. Let’s explore the common indicators.
Common Noises and Vibrations
One of the most frequent indicators of a bad wheel bearing is a distinct noise. This often manifests as a humming, growling, or roaring sound that typically gets louder with speed.
You might notice the sound changes when turning. For example, a bad left front wheel bearing might get louder when turning right, as more weight shifts to that side.
Vibrations felt through the steering wheel or floorboards can also signal a problem. These vibrations might become more pronounced at certain speeds.
Play in the Wheel Assembly
Excessive play or looseness in the affected wheel is a definitive symptom. This can be felt by grabbing the wheel at the 12 and 6 o’clock positions and trying to rock it.
Any noticeable movement, especially a clunking sensation, points directly to a worn bearing. This “play” can affect steering precision and tire wear.
It’s a critical safety check that can prevent further damage or loss of control, especially when navigating uneven terrain or carrying heavy loads.
ABS and Traction Control Warnings
Modern F-150s rely on wheel speed sensors, which are often integrated into the hub assembly. A failing wheel bearing can damage or misalign this sensor.
This can trigger warning lights on your dashboard, such as the Anti-lock Braking System (ABS) light or the Traction Control light. These warnings indicate a sensor malfunction.
Always address these lights promptly, as they can indicate a problem that impacts critical safety systems. A professional scan tool can confirm sensor issues.
Diagnosing Your 2017 Ford F150 Wheel Bearing Issue
Once you suspect a problem, a proper diagnosis is essential to confirm it’s indeed the wheel bearing and not another component. This saves time and ensures you repair the correct part.
These diagnostic steps are simple enough for most DIYers and can be performed safely with basic tools. Always prioritize safety during any vehicle inspection.
The Lift and Shake Test
Safely lift the suspected corner of your 2017 F150 off the ground using a sturdy jack and secure it with jack stands. Always use wheel chocks on the opposite wheels.
With the wheel off the ground, grasp the tire firmly at the 12 and 6 o’clock positions. Try to rock the wheel back and forth.
Next, try rocking it at the 3 and 9 o’clock positions. Significant play or a clunking noise indicates a bad wheel bearing or possibly a tie rod end.
Listening for the Growl
This test requires caution. With the vehicle safely lifted on jack stands, have a helper slowly rotate the wheel by hand.
Carefully place your hand on the spring or knuckle near the wheel bearing. A bad bearing will often transmit a grinding or rumbling sensation through these components.
Alternatively, you can use a mechanic’s stethoscope (or a long screwdriver to your ear) to pinpoint the source of the noise. This helps differentiate between a bearing and other rotating parts.
Visual Inspection Tips
Look for any signs of grease leaking from around the hub assembly. While not always present, a grease leak can indicate a damaged seal and a compromised bearing.
Check for uneven tire wear patterns, especially “cupping” or “scalloping.” This can be a secondary symptom of a worn bearing affecting alignment.
Inspect the brake components for any unusual wear or damage that might be related. Sometimes, a severely failed bearing can impact brake rotor runout.
Essential Tools and Parts for Your 2017 Ford F150 Wheel Bearing Replacement
Having the right tools and parts on hand makes the job smoother and safer. Don’t start until you’ve gathered everything you need.
Using the correct tools prevents damage to components and ensures proper reassembly. Quality parts are also crucial for longevity and performance.
Required Tools Checklist
You’ll need a reliable floor jack and at least two robust jack stands. Wheel chocks are also a must for safety.
A good set of sockets and wrenches, including a large socket for the axle nut (typically 36mm for the F-150), will be essential. A breaker bar will help with stubborn bolts.
Other vital tools include a torque wrench (capable of high torque for the axle nut and lug nuts), a hammer, a flat-head screwdriver, and possibly a pry bar.
You’ll also need a wire brush, penetrating oil, brake cleaner, and a small pick or hook tool for the ABS sensor wire. Safety glasses and gloves are non-negotiable.
Choosing the Right Replacement Hub Assembly
For your 2017 Ford F150 wheel bearing, you’ll be replacing the entire hub assembly. This integrated unit includes the bearing, wheel studs, and often the ABS sensor.
Ensure you purchase a hub assembly specifically designed for your 2017 Ford F150, taking into account whether it’s a 2WD or 4WD model. There are distinct differences.
Opt for a reputable brand to ensure durability and proper fitment. OEM (Original Equipment Manufacturer) or high-quality aftermarket options are recommended for longevity.
Some hub assemblies come with a pre-installed ABS sensor, which simplifies the replacement process. Verify this when purchasing your new part.
Step-by-Step: Replacing Your 2017 Ford F150 Wheel Bearing
This section provides a detailed, actionable guide to replacing the wheel bearing on your 2017 F-150. Follow these steps carefully for a successful and safe repair.
Remember, patience and attention to detail are key. If you encounter any difficulties, consult your truck’s service manual or a professional.
Safety First: Pre-Job Setup
Park your truck on a level, firm surface. Place wheel chocks behind the rear wheels if you’re working on the front, or in front of the front wheels if working on the rear.
Loosen the lug nuts on the wheel you’ll be working on while the truck is still on the ground. Just a half-turn or so is enough.
Jack up the front of your F-150 using the appropriate lift points, then secure it firmly on jack stands. Never rely solely on the jack. Remove the wheel and tire completely.
Disassembly Process
- Remove the Brake Caliper: Locate the two caliper mounting bolts (usually 18mm or 21mm). Remove them and carefully slide the caliper off the rotor. Do not let the caliper hang by the brake hose; support it with a bungee cord or wire to the frame.
- Remove the Brake Rotor: The rotor should slide off the wheel studs easily. If it’s stuck, a few taps with a rubber mallet on the hat of the rotor can help.
- Disconnect the ABS Sensor: Trace the ABS sensor wire from the hub assembly back to its connector. Disconnect it and carefully unclip the wire from any retainers on the knuckle.
- Remove the Axle Nut (4WD Models Only): For 4WD F-150s, you’ll need to remove the large axle nut (typically 36mm) from the center of the hub. This nut is often very tight and may require a breaker bar and significant force.
- Remove the Hub Assembly Bolts: On the back side of the steering knuckle, you’ll find three bolts (usually 18mm) that secure the hub assembly to the knuckle. Remove these bolts. They can be tight and sometimes corroded.
- Remove the Old Hub Assembly: With all bolts and the axle nut removed, the old hub assembly should slide out of the steering knuckle. You may need to use a hammer to tap it loose from behind. Be careful not to damage the dust shield.
Installing the New Hub Assembly
- Clean the Knuckle: Use a wire brush to thoroughly clean the mating surface on the steering knuckle where the new hub assembly will sit. Remove any rust or debris.
- Install the New Hub: Carefully slide the new hub assembly into the steering knuckle. Ensure the splines for the axle shaft (4WD) engage properly.
- Install Hub Assembly Bolts: Reinstall the three mounting bolts from the backside of the knuckle. Tighten them to factory specifications (consult your service manual, typically around 185 lb-ft or 250 Nm).
- Install Axle Nut (4WD Only): Reinstall the new axle nut. Tighten it to factory specifications (often over 200 lb-ft or 270 Nm). This nut is critical for bearing preload.
- Reconnect ABS Sensor: Plug in the new ABS sensor wire and secure it in its clips. Ensure the connection is snug and the wire is routed away from moving parts.
Reassembly and Final Checks
- Reinstall Rotor and Caliper: Slide the brake rotor back onto the wheel studs. Reinstall the brake caliper, ensuring the brake pads are properly seated. Tighten the caliper bolts to spec (usually around 129 lb-ft or 175 Nm).
- Reinstall Wheel: Mount the wheel and tire back onto the studs. Hand-tighten the lug nuts.
- Lower Vehicle and Torque: Lower the truck completely off the jack stands. Using your torque wrench, tighten the lug nuts in a star pattern to the manufacturer’s specifications (typically 150 lb-ft or 204 Nm for the F-150).
Pro Tip: Torque Specifications are Crucial! Always refer to your F-150’s service manual for exact torque specifications for all fasteners. Over-tightening can strip threads, and under-tightening can lead to dangerous failures. Don’t guess!
Post-Replacement Checks and Preventing Future Issues
Completing the replacement of your 2017 Ford F150 wheel bearing is a significant achievement. However, your work isn’t quite done yet. A few final steps ensure everything is operating correctly and safely.
Proper post-installation checks and ongoing maintenance will extend the life of your new components and keep your F-150 running smoothly for years to come.
Test Drive and Alignment
After lowering your truck, pump the brake pedal several times to restore pressure before driving. This is a critical safety step.
Take your F-150 for a short test drive on a quiet road. Listen for any unusual noises, feel for vibrations, and check that the steering feels normal.
While a wheel bearing replacement itself doesn’t directly alter alignment, it’s a good practice to have your truck’s alignment checked, especially if you noticed uneven tire wear or any steering issues prior to the repair. This ensures optimal tire life and handling.
Maintenance for Longevity
Regularly inspect your wheels and tires for signs of unusual wear. This can be an early indicator of developing issues with suspension or bearings.
If you frequently tow heavy loads or venture off-road, these activities put additional stress on your wheel bearings. Consider more frequent inspections and perhaps even higher-quality aftermarket components designed for heavy-duty use.
Keep your tires properly inflated. Incorrect tire pressure can contribute to premature wear on various suspension and drivetrain components, including wheel bearings.
