Problem: Recognizing a Failing 2017 Ford Explorer Wheel Bearing
A failing 2017 Ford Explorer wheel bearing will typically announce itself through distinct auditory and tactile cues. You'll likely hear a humming, rumbling, or grinding noise that gets louder with speed, especially when turning. This sound often changes pitch or intensity when you steer left or right, indicating which side is affected. Ignoring these symptoms can lead to complete bearing failure, potentially causing the wheel to detach.
- Humming/grinding noise increases with speed.
- Noise changes pitch when turning.
- Vibration felt through the steering wheel.
- Wheel may feel loose or wobbly.
This mechanism is critical for allowing your wheels to rotate freely and smoothly while supporting the vehicle's weight. When this component begins to fail, it compromises both performance and safety.
Understanding Wheel Bearing Function
The wheel bearing is a set of steel balls or rollers nestled between two metal rings, housed within the hub assembly. Its primary job is to reduce friction, enabling your wheels to spin with minimal resistance. It must also withstand significant loads from driving, braking, and cornering. A healthy wheel bearing ensures a stable, quiet ride.
Common Symptoms to Watch For
Pay close attention to any changes in your 2017 Ford Explorer's driving behavior. Beyond the tell-tale noises, you might feel vibrations through the steering wheel or the entire vehicle, particularly at higher speeds. A loose or wobbly steering wheel is another significant indicator. Sometimes, a worn bearing can even lead to premature brake wear because the damaged hub assembly can cause the rotor to run out of true.
Such precision is paramount for safe vehicle operation.
The primary consideration involves listening for subtle changes.
Causes and Solutions for Wheel Bearing Issues
What causes a 2017 Ford Explorer wheel bearing to fail prematurely? The most common culprits include wear and tear from normal driving, especially on rough roads or during frequent hard cornering. Exposure to water, dirt, and road salt can corrode the bearing's internal components, breaking down the protective grease. Even minor impacts, like hitting a deep pothole, can shock and damage a bearing. Manufacturing defects, though less common, can also be a cause.
It is imperative to acknowledge that improper maintenance can accelerate wear.
When faced with a diagnosed faulty wheel bearing, replacement is the only viable solution. Attempting to repair a damaged bearing is generally not feasible or recommended. The procedure involves removing the wheel, disconnecting brake components, and then unbolting the hub assembly that houses the wheel bearing. The old bearing is pressed out, and a new one is pressed into the new hub assembly, which is then reinstalled.
Replacing a worn wheel bearing is essential for restoring vehicle safety and preventing catastrophic failure.
Our analysis indicates that replacement is a standard repair.
The Replacement Process
Replacing a 2017 Ford Explorer wheel bearing usually requires specialized tools, such as a hydraulic press, to safely remove and install the bearing and hub. It's often more practical and cost-effective to replace the entire hub assembly, which typically includes the new wheel bearing already pressed in. This simplifies the job and reduces the risk of damaging the new bearing during installation.
Inspect the steering knuckle and surrounding suspension components for any signs of damage or corrosion during the bearing replacement; addressing these simultaneously can prevent future issues.
The decision to replace the hub assembly is often driven by efficiency.
Preventing Future Wheel Bearing Problems
How can you prevent your 2017 Ford Explorer's wheel bearings from failing prematurely? Regular maintenance and mindful driving habits are key. Ensure your vehicle's suspension and steering components are inspected periodically, as misalignment can put undue stress on wheel bearings. When driving, try to avoid hitting potholes or curbs forcefully, as these impacts can damage the bearing's delicate internal structure.
Best Practices for Longevity
While wheel bearings are designed for the life of the vehicle, they aren't indestructible. Driving through deep water, especially after the bearing has accumulated miles, can compromise the seal and wash out grease, leading to corrosion. If you frequently drive in harsh conditions (e.g., off-road, salted roads), it's wise to have your wheel bearings inspected more frequently than the standard maintenance schedule might suggest.
Understanding this principle is fundamental to extending component life.
When driving, be mindful of road conditions.
Clean wheel hubs thoroughly before installing new bearings or hubs to ensure a flush, secure fit and prevent debris from causing premature wear.
Proactive checks are paramount for early detection of potential issues.
