Understanding Your Explorer’s Wheel Bearings
Wheel bearings are crucial components that allow your wheels to spin freely with minimal friction. They support the weight of the vehicle and are constantly exposed to varying loads and road conditions.
For your 2016 Ford Explorer, these bearings are typically sealed units, often integrated into a hub assembly. This means that if the bearing fails, you’ll usually replace the entire hub assembly.
Front vs. Rear Assemblies
The front and rear wheel bearing assemblies on a 2016 Ford Explorer can differ slightly in design and the steps required for replacement. Front assemblies are part of the steering knuckle, while rear ones are part of the rear axle assembly.
Understanding these differences is key to gathering the correct parts and tools for your specific repair.
Symptoms of a Failing 2016 Ford Explorer Wheel Bearing
Catching the signs of a worn-out wheel bearing early can prevent further damage and keep you safe. Pay close attention to any changes in your vehicle’s sound or feel.
The Tell-Tale Noises
One of the most common indicators is a distinctive noise. This can manifest as a persistent humming, grinding, growling, or even a roaring sound that often gets louder with speed.
The sound might change when turning; for instance, a left turn could put more load on the right wheel bearing, making a failing right bearing noise more prominent.
Listen for sounds that are distinctly different from tire noise. A bad bearing’s sound is usually metallic or mechanical, not rubbery.
Vibrations and Play
Beyond noise, you might notice vibrations in the steering wheel, floorboard, or even the entire vehicle. These vibrations can become more pronounced at certain speeds.
In severe cases, you might feel looseness or “play” in the affected wheel. This is a critical safety concern and requires immediate attention.
If you suspect a problem, it’s always best to investigate promptly rather than waiting for symptoms to worsen.
Diagnosing the Problem: Pinpointing the Culprit
Accurately diagnosing which wheel bearing is failing is crucial before starting any repair. A misdiagnosis can lead to wasted time and money.
The Lift Test
This is a classic DIY diagnostic method. Safely lift the vehicle using a jack and jack stands, ensuring the suspected wheel is off the ground.
Grasp the wheel at the 12 and 6 o’clock positions, then try to rock it in and out. Excessive play or clunking indicates a loose or failing wheel bearing.
Repeat this at the 3 and 9 o’clock positions. While this can also indicate tie rod or ball joint issues, combined with noise, it strongly points to the bearing.
Next, spin the wheel by hand. Listen carefully for any grinding, roughness, or uneven rotation. A healthy bearing should spin smoothly and silently.
Road Test Clues
A controlled road test can also help. Drive at varying speeds and listen for the noise. Often, the sound will intensify or change pitch with speed.
Gently swerve the vehicle side to side (safely and on an empty road). If the noise diminishes or changes when turning one way, it can help isolate the side of the failing bearing.
For example, if the noise lessens when turning left, it might indicate a problem with the right wheel bearing, as the load shifts away from it.

Replacing Your 2016 Ford Explorer Wheel Bearing: A Step-by-Step Guide
This section outlines the general process. Always refer to your vehicle’s specific service manual for exact procedures and torque values.
Front Wheel Bearing Replacement
Preparation and Lifting
- Loosen Lug Nuts: While the vehicle is still on the ground, use a breaker bar to slightly loosen the lug nuts on the wheel you’ll be working on.
- Lift Vehicle: Safely lift the front of the Explorer with a jack and place it securely on jack stands. Ensure the vehicle is stable.
- Remove Wheel: Fully remove the lug nuts and the wheel.
Disassembly
- Remove Brake Caliper: Locate the two caliper guide pin bolts (usually 13mm or 15mm) on the back of the caliper. Remove them and carefully slide the caliper off the rotor. Do not let it hang by the brake line; support it with a bungee cord or wire.
- Remove Brake Rotor: The rotor should slide off the hub. If it’s stuck, a few taps with a rubber mallet can help.
- Remove ABS Sensor (if applicable): Disconnect and carefully remove the ABS sensor from the knuckle assembly. Be gentle, as these can be brittle.
- Remove Axle Nut: Use your large axle nut socket and breaker bar to remove the large nut securing the axle shaft to the hub. This can be very tight.
- Separate Axle Shaft: Push the axle shaft inward to disengage it from the hub assembly. Sometimes a few taps with a brass punch and hammer are needed, but be careful not to damage the threads.
Removing the Old Bearing
- Remove Hub Bolts: On the back side of the steering knuckle, you’ll find three or four bolts holding the hub assembly to the knuckle. These are usually substantial (e.g., 18mm or 21mm). Remove these bolts.
- Remove Hub Assembly: With the bolts out and the axle shaft separated, the old hub assembly should now come out. It might be seized due to rust. A hub puller or a few strategic taps with a heavy hammer can help persuade it off.
- Clean Mounting Surface: Thoroughly clean the mounting surface on the steering knuckle where the new hub will sit. Remove all rust and debris with a wire brush.
Installing the New Bearing
- Apply Anti-Seize: Apply a thin layer of anti-seize compound to the clean mounting surface on the knuckle. This helps prevent future rust and makes removal easier next time.
- Install New Hub: Carefully align the new 2016 Ford Explorer wheel bearing hub assembly with the bolt holes on the steering knuckle. Ensure the axle splines also align with the hub.
- Install Hub Bolts: Insert and hand-tighten the three or four hub bolts from the back.
- Torque Hub Bolts: Using your torque wrench, tighten the hub bolts to the manufacturer’s specified torque (consult your service manual). This is critical for proper function and safety.
Reassembly
- Re-engage Axle Shaft: Push the axle shaft fully into the new hub.
- Install Axle Nut: Thread on the new axle nut (if provided, or reuse the old one with thread locker if specified) and tighten it. This nut also requires a specific torque, often quite high.
- Reinstall ABS Sensor: Carefully reattach the ABS sensor and its wiring.
- Reinstall Brake Rotor: Slide the brake rotor back onto the hub.
- Reinstall Brake Caliper: Place the brake caliper back over the rotor and reinsert the guide pin bolts. Torque these bolts to specification.
- Reinstall Wheel: Place the wheel back on the studs and hand-tighten the lug nuts.
Rear Wheel Bearing Replacement
The rear wheel bearing replacement on a 2016 Ford Explorer follows a very similar procedure to the front, involving the removal of brake components, the axle nut, and the hub assembly bolts.
Key differences might include the specific size of the axle nut, the routing of the ABS sensor wiring, and potentially the need to disconnect a parking brake cable if it’s integrated differently. Always consult your service manual for precise rear axle instructions.
Post-Replacement Checks and Maintenance Tips
After all components are reassembled, lower the vehicle and finish tightening the lug nuts to their specified torque. This is crucial for wheel retention.
Before driving, pump the brake pedal several times to restore pressure to the brake caliper. Take a short test drive at low speeds, listening for any abnormal noises and checking for proper braking function.
Monitor the new bearing for the first few hundred miles. If any noises or vibrations return, pull over safely and investigate immediately.
To maximize the life of your new wheel bearing, avoid driving through deep puddles or floodwaters, as water intrusion can contaminate the bearing grease. Also, ensure your wheels are balanced and aligned correctly, as excessive vibration can shorten bearing life.
When to Call a Pro: Recognizing Your Limits
While replacing a 2016 Ford Explorer wheel bearing is a common DIY task, there are times when professional help is the best course of action. If you encounter severely seized bolts, lack the specialized tools (like a hub puller if needed), or feel uncomfortable with any step, don’t hesitate to contact a certified mechanic.
Working on suspension and brake components is critical for safety. If you’re unsure, a professional can complete the job correctly and safely, providing peace of mind.
