This article addresses a common issue for 2018 Ford F-150 owners: wheel bearing failure. We’ll cover how to diagnose a bad wheel bearing, discuss replacement options, and offer some practical advice based on real-world experience. Replacing a wheel bearing isn’t always straightforward, and understanding the nuances specific to the 2018 F-150 can save you time, money, and frustration.
The telltale signs of a failing wheel bearing are often subtle at first, gradually worsening over time. Catching it early can prevent more serious damage and a potentially dangerous situation. Here are some key indicators:
The Grumbling Noise
A rumbling or grinding noise that increases with speed is a classic symptom. This noise often changes in intensity when turning, as the load shifts from one side of the vehicle to the other. For example, if you hear the noise louder when turning left, the right wheel bearing is likely the culprit, and vice-versa.
Feeling the Vibration
A vibration felt through the steering wheel or floorboard, especially at higher speeds, can also indicate a failing wheel bearing. This vibration might be intermittent at first but will become more consistent as the bearing deteriorates.
Play in the Wheel
With the vehicle safely raised and supported, grab the tire at the 12 and 6 o’clock positions. Try to rock the wheel back and forth. Excessive play suggests a worn wheel bearing or other suspension component issue. This test is crucial for confirming your diagnosis.
ABS Issues
Sometimes, a failing wheel bearing can interfere with the ABS (Anti-lock Braking System) sensor. This may trigger the ABS light on your dashboard. Diagnostic trouble codes (DTCs) related to the ABS system for a specific wheel might point to a problem with the wheel bearing.
Uneven Tire Wear
While uneven tire wear can have many causes, a failing wheel bearing can contribute to it. Pay attention to whether one tire is wearing significantly faster or differently than the others, as this could be a sign of a wheel bearing problem.
You have a few choices when it comes to replacing a wheel bearing on your 2018 F-150. The best option depends on your budget, mechanical skills, and available tools.
Complete Hub Assembly
Replacing the entire hub assembly is often the easiest and fastest option. This involves removing the old hub, which includes the bearing, and bolting on a new one. This method minimizes the need for specialized tools like a hydraulic press.
Bearing Only Replacement
Replacing only the bearing itself is generally more cost-effective but requires more labor and specialized tools. You’ll need to remove the hub assembly and use a press to remove the old bearing and install the new one. This is best left to experienced DIYers or professionals.
Choosing a Brand
Consider brands like Timken, SKF, or Motorcraft when purchasing a replacement wheel bearing or hub assembly. These brands are known for their quality and durability, ensuring a longer lifespan for your repair. Cheaper, unbranded options might save you money initially but could lead to premature failure and more frequent replacements.
Having tackled a few wheel bearing replacements on 2018 F-150s, here’s some advice based on my experiences:
The Rust Factor
The biggest challenge I’ve encountered is dealing with rust, especially in areas that experience harsh winters. Penetrating oil is your best friend. Apply it liberally to all bolts and connections well in advance of starting the job.
Torque is Key
Always use a torque wrench when tightening the hub assembly bolts and axle nut. Over-tightening can damage the bearing, while under-tightening can lead to premature failure and potentially dangerous situations. Refer to your vehicle’s service manual for the correct torque specifications.
ABS Sensor Care
The ABS sensor is often attached to the hub assembly. Be extremely careful when removing and reinstalling the sensor, as it’s easily damaged. Consider replacing the sensor if it shows any signs of wear or damage.
Don’t Skip the Alignment
After replacing a wheel bearing, it’s a good idea to get a wheel alignment. This ensures that your tires wear evenly and your vehicle handles properly.
Noise Isolation is Tricky
It’s easy to misdiagnose wheel bearing noise as tire noise, especially with aggressive tires. Try rotating your tires to see if the noise changes. If it doesn’t, the wheel bearing is the more likely culprit.
Here’s a breakdown of steps that can make a difference based on hands on experience:
-
Soak Everything: Begin several days before the repair by soaking the wheel bearing assembly and all surrounding nuts and bolts with penetrating oil. This dramatically reduces the chance of snapping a bolt during removal.
-
Heat things up: Use a propane torch to apply moderate heat to the hub area, around the bolts. The heat helps expand the metal, breaking the bonds formed by rust. Be careful not to overheat any components, particularly the ABS sensor.
-
Hammer Time (Judiciously): Once all bolts are removed, the hub assembly might still be stuck due to corrosion. Use a rubber mallet to gently tap around the hub to break it free. Avoid using excessive force, which could damage surrounding components.
-
Anti-Seize is your Friend: Before reassembling, apply a thin layer of anti-seize compound to all mating surfaces and bolt threads. This will prevent future corrosion and make disassembly easier next time.
-
Double-Check the Torque: Torque all bolts to the manufacturer’s specifications in a star pattern. This ensures even pressure and prevents warping. Double-check the torque values after the first 50 miles of driving.
