Understanding Your 2015 Ford Explorer Wheel Bearing System
Wheel bearings are vital for your vehicle’s operation. They allow the wheels to rotate with minimal friction. In the 2015 Ford Explorer, these are typically integrated into a hub assembly.
What is a Wheel Bearing and Why Does it Matter?
A wheel bearing is a set of steel balls or rollers held together by a metal ring. These components reduce friction as the wheel spins. Without them, the wheel wouldn’t turn smoothly.
They are crucial for safe driving. A properly functioning bearing ensures stable handling and efficient power transfer. It directly impacts your vehicle’s overall performance.
Common Causes of Wheel Bearing Failure
Several factors can lead to wheel bearing failure. High mileage is a primary culprit, as bearings simply wear out over time. Road impacts, like hitting potholes, can also damage them.
Driving through deep water or mud can compromise seals, allowing contaminants in. This leads to premature wear and corrosion. Off-road enthusiasts should be particularly mindful of this risk.
Spotting the Signs: Diagnosing a Failing 2015 Ford Explorer Wheel Bearing
Early diagnosis is key to preventing further damage. Pay close attention to any changes in your vehicle’s behavior. A bad wheel bearing often gives clear warnings.
The Tell-Tale Noises: Growls, Hums, and Clicks
The most common symptom is noise. You might hear a consistent humming or growling sound. This often gets louder with speed.
It can also change pitch when turning. A growl that intensifies when turning one way, and lessens when turning the other, often indicates a bad bearing on the side opposite the turn where the noise increases. For example, a growl on a right turn might indicate a failing left front wheel bearing.
Clicking or clunking sounds might also be present. These can sometimes indicate a loose bearing or damaged CV joint. It’s important to differentiate.
Vibration and Steering Wheel Play
A failing wheel bearing can introduce vibrations. You might feel these through the steering wheel or floorboards. The vibrations can become more pronounced at certain speeds.
In severe cases, you might notice excessive play in the steering wheel. This means the wheel feels loose or imprecise. It’s a significant safety concern.
Visual Inspection Clues
While harder to spot, visual cues can exist. Look for uneven tire wear, especially on one side. This can suggest a bearing issue.
Also, check for grease leaks around the hub area. A compromised seal allows grease to escape. This leaves the bearing vulnerable to dirt and moisture.
The “Shake Test” for Play
This is a more definitive diagnostic method. Safely jack up the suspected wheel. Grab the wheel at the 12 and 6 o’clock positions.
Try to rock it back and forth. Any significant play or clunking indicates a loose bearing. Repeat this at the 3 and 9 o’clock positions.
A slight bit of play might be normal for some suspension components. However, excessive movement usually points to a failing hub assembly. If you feel any grinding while rotating the wheel by hand, that’s another strong indicator.
Essential Tools and Parts for the DIYer
Before you begin, gather all necessary tools and parts. This ensures a smooth and efficient repair process. Being prepared saves time and frustration.
Required Tools and Safety Gear
You’ll need a robust jack and jack stands for safety. A lug wrench is essential for wheel removal. A torque wrench is critical for proper reassembly.
Other tools include a large breaker bar, various socket sizes (especially for the axle nut and caliper bolts), a pry bar, and a hammer. A wire brush helps clean mounting surfaces. Always wear safety glasses and gloves.
For the 2015 Ford Explorer wheel bearing replacement, you might also need a specific axle nut socket. These are often large, such as 32mm or 36mm. Confirm the size for your specific Explorer model.
Choosing the Right Replacement Hub Assembly
Your 2015 Ford Explorer uses an integrated wheel bearing and hub assembly. You cannot just replace the bearing itself. You must replace the entire hub unit.
Always opt for a high-quality replacement part. OEM (Original Equipment Manufacturer) or reputable aftermarket brands are best. Cheap parts often fail prematurely.
Ensure the new hub assembly matches your Explorer’s specifications. Verify if it’s for the front or rear, and for your specific trim level (e.g., FWD or AWD). This prevents compatibility issues.
Step-by-Step Replacement: How to Change a 2015 Ford Explorer Wheel Bearing
Replacing a wheel bearing is a moderate DIY task. It requires patience and adherence to safety protocols. If unsure, always consult a professional.
Safety First: Preparation is Key
Park your Explorer on a flat, stable surface. Engage the parking brake. Block the wheels that will remain on the ground.
Loosen the lug nuts on the affected wheel while it’s still on the ground. Then, jack up the vehicle and secure it on jack stands. Never work under a vehicle supported only by a jack.
Remove the wheel completely. Now you have clear access to the brake and suspension components. This is the foundation for a safe repair.
Disassembly: Getting to the Hub
First, remove the brake caliper. Use a C-clamp to push the piston back slightly. Unbolt the caliper bracket and carefully hang the caliper. Do not let it hang by the brake line.
Remove the brake rotor. It might be held by a small retaining screw or just rusted in place. A few taps with a rubber mallet can help free it.
Next, you need to address the axle nut. This is usually very tight. You’ll need your large breaker bar and appropriate socket. You might also need to remove a cotter pin and dust cap first.
Removing the Old Hub Assembly
With the axle nut off, locate the bolts holding the hub assembly to the knuckle. There are typically three or four bolts on the backside. These can be challenging to access.
Remove these bolts. The old hub assembly might be seized in place. Use a hammer to carefully tap around the hub flange. Avoid hitting the axle shaft directly.
A slide hammer with a hub puller attachment can be invaluable here. If you don’t have one, persistent but careful tapping and prying can work. Be patient; rust is often your biggest adversary.
Installing the New Wheel Bearing Hub
Clean the mating surface on the steering knuckle thoroughly. Use a wire brush to remove rust and debris. A clean surface ensures proper seating of the new hub.
Apply a thin layer of anti-seize compound to the mating surface. This will prevent future seizing. Carefully slide the new hub assembly into place.
Insert the hub mounting bolts from the backside. Hand-tighten them first. Ensure the axle shaft splines align and slide into the new hub assembly.
Reassembly and Final Checks
Tighten the hub mounting bolts to the manufacturer’s specifications. This is where your torque wrench comes in. Consult your service manual for exact torque values.
Reinstall the axle nut. Tighten it to the specified torque. This nut is crucial for holding the hub assembly together.
Reinstall the brake rotor, caliper bracket, and then the caliper. Ensure all bolts are torqued correctly. Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground. Then, use your torque wrench to tighten the lug nuts in a star pattern. This ensures even pressure and prevents wheel wobble.
Post-Replacement: Ensuring Long-Term Performance and Safety
The job isn’t done after the last bolt is tightened. Several steps are crucial for safety and longevity. Don’t skip these final checks.
Torque Specifications and Why They’re Critical
Every bolt on your suspension and braking system has a specific torque value. Adhering to these is non-negotiable. Overtightening can strip threads or stress components.
Undertightening can lead to loose parts and catastrophic failure. Always use a calibrated torque wrench. Double-check all torque settings against your 2015 Ford Explorer service manual.
For example, the axle nut is typically torqued to a very high specification, often exceeding 200 ft-lbs. The caliper bracket bolts and lug nuts also have specific requirements. Proper torque ensures the new 2015 Ford Explorer wheel bearing operates as intended.
Test Driving and Break-In Tips
After completing the replacement, take your Explorer for a cautious test drive. Start slowly and listen for any unusual noises. Gently apply the brakes to ensure they feel normal.
Gradually increase speed, paying attention to steering feel and vibrations. If everything feels normal, you’ve likely done a good job. If you notice any issues, re-check your work.
There’s no specific “break-in” for a wheel bearing. However, new brake pads (if replaced) will need proper bedding. Follow manufacturer recommendations for any other new components.
Preventative Maintenance for Your Explorer’s Wheel Bearings
Regular inspections are your best defense. During tire rotations or brake checks, inspect the wheel bearings. Look for play, noise, or grease leaks.
Avoid harsh impacts like hitting potholes at speed. If you frequently drive off-road, consider more frequent inspections. Water crossings and muddy trails put extra stress on these components.
Ensure your tires are properly balanced and aligned. Imbalanced tires can cause vibrations that prematurely wear bearings. Good maintenance practices extend the life of all your vehicle’s components.
When to Call a Pro: Knowing Your Limits
While many DIYers can tackle a wheel bearing replacement, there are times when professional help is the smarter choice. Your safety and the integrity of your vehicle are paramount.
Complex Issues and Specialized Tools
Sometimes, a seemingly straightforward job can uncover deeper problems. Seized bolts, rusted components, or damaged knuckles can complicate the process. Specialized tools, like a heavy-duty press, might be needed if the bearing is not a hub assembly type (though for the 2015 Explorer, it’s typically an assembly).
If you lack the necessary tools or run into unexpected complications, don’t hesitate. A professional mechanic has the experience and equipment to handle these issues efficiently. They can prevent further damage.
Safety Concerns and Experience Gaps
Working on suspension and braking components requires a good understanding of mechanics. If you’re uncomfortable or unsure about any step, call a licensed professional. Incorrect installation can have serious safety consequences.
For instance, improper torque on the axle nut or hub bolts can lead to wheel separation. If you’re a novice DIYer, consider watching several tutorials first or assisting an experienced friend. When in doubt, entrust your 2015 Ford Explorer wheel bearing replacement to someone with proven expertise.
