Understanding Your 2016 Ford Explorer Rear Wheel Bearing
The wheel bearing is a critical component that allows your wheels to spin freely with minimal friction. In your 2016 Ford Explorer, it’s typically part of a sealed hub assembly at each wheel.
These assemblies are designed to withstand tremendous loads and high rotational speeds, but they aren’t invincible. Over time, wear and tear, impacts, and exposure to the elements can cause them to fail.
A healthy wheel bearing is essential for proper wheel rotation, handling, and even the function of your anti-lock braking system (ABS). When it starts to go bad, you’ll definitely notice.
Anatomy of a Modern Wheel Bearing Assembly
Modern vehicles like the 2016 Ford Explorer often use a hub-and-bearing assembly. This means the bearing, hub, and often the wheel studs are a single, sealed unit.
This design simplifies replacement compared to older pressed-in bearing styles. However, it also means you typically replace the entire assembly, not just the bearing itself.
Inside this sealed unit are precision-machined races and either ball or roller bearings, lubricated with grease and protected by seals. These seals are crucial for keeping contaminants out and lubricant in.
Why Do Wheel Bearings Fail?
Several factors contribute to wheel bearing failure. High mileage is a common culprit, as the internal components simply wear out over thousands of rotations.
Impacts from potholes, curbs, or off-road obstacles can also damage the bearing. These sudden forces can brinell the races or damage the internal rollers.
Water and dirt intrusion, especially if seals are compromised, can wash away grease or introduce abrasive particles. This accelerates wear and leads to premature failure.
Diagnosing a Failing 2016 Ford Explorer Rear Wheel Bearing
Catching a bad wheel bearing early can prevent further damage to other components, like the axle shaft or brake system. Knowing the signs is your first line of defense.
The symptoms of a failing wheel bearing tend to be consistent across many vehicles, including your Explorer. Pay close attention to any new noises or changes in how your vehicle feels.
Never ignore these warnings. A severely failed bearing can lead to a wheel seizing or even detaching, creating an extremely dangerous situation on the road.
Common Symptoms of a Bad Rear Wheel Bearing
The most common symptom is a distinctive noise. This often presents as a humming, growling, or roaring sound that typically gets louder with vehicle speed.
The pitch of the noise might change when turning. For example, a bad left rear bearing might become louder when turning right, as more weight shifts onto that side.
You might also feel vibrations in the steering wheel or floorboard, especially at higher speeds. In severe cases, there could be noticeable looseness or play in the wheel.
A less common but serious symptom is uneven tire wear, which indicates an alignment issue potentially caused by excessive play in the wheel bearing.
Pinpointing the Noise: Front vs. Rear, Left vs. Right
Diagnosing which bearing is bad can be tricky, as noises often resonate throughout the vehicle. Start by listening carefully to where the sound seems to originate.
A simple test involves driving at a speed where the noise is prominent and gently weaving the vehicle side to side. If the sound changes or intensifies when turning in one direction, it helps narrow down the side.
For example, if the noise gets louder when turning right, it often points to a problem on the left side of the vehicle, as the vehicle’s weight shifts to the outer wheel. This applies to both front and rear bearings.
The Lift and Shake Test
For a more definitive diagnosis, you’ll need to safely lift the rear of your Explorer. Chock the front wheels and use sturdy jack stands under the frame.
With the wheel off the ground, try to shake the wheel by grabbing it at the 12 and 6 o’clock positions, then at 3 and 9 o’clock. Any noticeable play or clunking indicates a worn bearing.
Next, spin the wheel by hand. Listen for any grinding, roughness, or uneven rotation. You might even feel resistance or a “notchiness” as you spin it.
Safety First: What to Do If You Suspect Failure
If you suspect a bad rear wheel bearing, prioritize safety. Avoid long trips or high speeds until the issue is addressed.
If the noise is severe or there’s noticeable looseness, it’s best to have the vehicle towed to a repair shop or perform the repair immediately. Driving on a severely compromised bearing is extremely risky.
For your safety and the safety of others, never postpone wheel bearing repairs. It’s a critical component that directly impacts vehicle control.

Step-by-Step Replacement: Your 2016 Ford Explorer Rear Wheel Bearing
This section provides a detailed guide to replacing the rear wheel bearing assembly on your Explorer. Take your time, follow each step carefully, and prioritize safety above all else.
This process assumes a basic understanding of automotive repair. If at any point you feel uncomfortable, consult a professional mechanic.
The average DIYer can accomplish this task, but it requires patience and adherence to proper procedures, especially regarding torque specifications.
1. Prepare the Vehicle and Gather Tools
- Park your Explorer on a flat, level surface.
- Chock the front wheels securely to prevent any movement.
- Loosen the lug nuts on the rear wheel you’ll be working on, but do not remove them yet.
- Using your floor jack, lift the rear of the vehicle until the wheel is off the ground.
- Place jack stands securely under the frame, near the suspension mounting points. Never work under a vehicle supported only by a jack.
- Lower the vehicle onto the jack stands and remove the floor jack.
2. Remove the Wheel and Brake Components
- Completely remove the lug nuts and then the wheel. Set it aside safely.
- Locate the brake caliper. You’ll need to remove two bolts (usually 13mm or 15mm) that hold the caliper to the caliper bracket.
- Carefully remove the caliper and suspend it using a bungee cord or wire from the suspension spring. Do not let it hang by the brake hose, as this can damage the hose.
- Remove the two larger bolts (often 18mm or 19mm) that hold the caliper bracket to the steering knuckle. Remove the bracket.
- Remove the brake rotor. It may be held on by a small T30 Torx screw or simply stuck to the hub due to rust. If stuck, a few taps with a mallet can help loosen it.
3. Access and Remove the Axle Nut
- You should now see the axle shaft protruding through the center of the hub assembly.
- Remove the dust cap (if present) from the center of the hub to expose the axle nut.
- Using your large socket (e.g., 32mm or 36mm) and a breaker bar, loosen the axle nut. This nut is often very tight, so it might require significant force.
- Once loosened, remove the axle nut completely.
4. Remove the Old Hub Assembly
- Locate the bolts that secure the hub assembly to the knuckle. There are typically three or four bolts on the backside of the knuckle (often 15mm or 18mm).
- You may need to disconnect the ABS sensor wire from the hub assembly. Follow the wire to its connector and carefully unplug it.
- Remove these hub assembly bolts. They can be tight and sometimes difficult to access.
- With the bolts removed, the old hub assembly should slide off the axle shaft. If it’s seized due to rust, use a hammer or mallet to gently tap it from the backside until it breaks free. Be careful not to damage the axle shaft threads.
5. Install the New Hub Assembly
- Clean the mating surface on the knuckle thoroughly with a wire brush to ensure the new hub sits flush. Apply a thin layer of anti-seize lubricant.
- Carefully slide the new hub assembly onto the axle shaft and align it with the bolt holes on the knuckle.
- Insert the new hub assembly bolts from the backside and hand-tighten them.
- Reconnect the ABS sensor wire to the new hub assembly. Ensure the connection is secure.
- Tighten the hub assembly bolts to the manufacturer’s specified torque. Refer to your Explorer’s service manual for the exact specification, which is crucial for bearing longevity.

- Lug Nuts: Typically 100 ft-lbs (135 Nm) for most Ford Explorers.
Always double-check these values in your specific 2016 Ford Explorer service manual, as they can vary slightly.
6. Reassemble Brake Components and Wheel
- Reinstall the brake rotor onto the new hub assembly. If there was a Torx screw, secure it.
- Reinstall the brake caliper bracket and tighten its two large bolts to the specified torque.
- Slide the brake caliper back over the rotor and reattach its two guide pin bolts. Tighten these to their much lower specified torque.
- Reinstall the wheel onto the hub. Hand-tighten the lug nuts.
- Raise the vehicle off the jack stands with your floor jack, then remove the jack stands.
- Lower the vehicle completely.
- Using your torque wrench, tighten the lug nuts in a star pattern to the factory specification (usually 100 ft-lbs).
Post-Replacement Checks and Test Drive
Once everything is reassembled, a few final checks are critical before you hit the road. This ensures everything is secure and functioning correctly.
Don’t skip these steps. They are essential for confirming the success of your repair and for your continued safety.
A proper test drive can reveal any lingering issues or confirm that your new 2016 Ford Explorer rear wheel bearing is working perfectly.
Double-Check All Fasteners
Go back over every bolt you touched: hub assembly bolts, axle nut, caliper bracket bolts, caliper guide pin bolts, and lug nuts. Ensure they are all torqued to specification.
Visually inspect the brake lines and ABS sensor wire to ensure they are not pinched or damaged. Make sure the ABS sensor is properly seated.
Pump the brake pedal several times before starting the engine to restore pressure to the brake system. The pedal might feel soft initially if the caliper was manipulated.
Test Drive for Noise and Feel
Take your Explorer for a test drive on a quiet road. Start slowly and gradually increase speed.
Listen carefully for any residual noises or new sounds. The humming or growling should be gone.
Pay attention to how the vehicle feels. There should be no vibrations or abnormal sensations coming from the rear.
Monitoring for Early Warning Signs After Repair
Even with a new bearing, it’s a good idea to monitor its performance for the first few weeks. Listen for any unusual noises, especially when turning or at highway speeds.
If you encounter any issues, re-check your work or consider having a professional inspect it. Sometimes, a component adjacent to the bearing might have been damaged by the old failing unit.
This vigilance ensures that your repair holds up and provides lasting reliability for your Ford Explorer.
Extending the Life of Your Wheel Bearings
While wheel bearings are wear items, there are steps you can take to maximize their lifespan and prevent premature failure.
Proactive maintenance and mindful driving habits can make a significant difference in how long your components last.
