This article will help you diagnose and potentially fix common issues with your 2018 F150’s front wheel bearings. We’ll cover the symptoms, potential causes, and provide practical steps for inspection and repair, saving you time and money. We’ll also explore some less commonly discussed factors that impact wheel bearing life on these trucks.
Front wheel bearings are crucial for smooth and safe operation of your 2018 F150. They allow the wheels to rotate freely with minimal friction. A failing wheel bearing can lead to a variety of issues, impacting handling, fuel economy, and even safety. It’s important to address these problems promptly.
Common Symptoms of a Failing Wheel Bearing
Several telltale signs indicate a potential problem with your 2018 F150’s front wheel bearings. Paying attention to these symptoms can help you catch the issue early and prevent more serious damage.
- A grinding or humming noise: This noise often increases with speed and may change or disappear when turning.
- Vibration in the steering wheel: A worn bearing can cause noticeable vibrations, particularly at higher speeds.
- Loose or wobbly wheel: If you can feel play in the wheel when it’s jacked up, the bearing is likely failing.
- Uneven tire wear: A bad wheel bearing can cause the tire to wear unevenly due to misalignment or excessive play.
- ABS malfunction: In some cases, a failing wheel bearing can interfere with the ABS sensor, triggering a warning light.
Identifying the Source of the Noise
Pinpointing which wheel bearing is causing the problem can save you time and effort. Here are some tips:
- Listen carefully: Pay attention to which side the noise is coming from while driving.
- Test while turning: Turning the steering wheel slightly while driving can help isolate the noisy bearing. The noise will usually get louder when turning in the direction of the bad bearing.
- Jack up the truck: With the truck safely supported, spin each front wheel by hand. Listen for any grinding, clicking, or rough noises.
- Check for play: Grab the wheel at the 12 and 6 o’clock positions and try to rock it back and forth. Any noticeable play indicates a worn bearing.
Once you suspect a problem with your 2018 F150’s front wheel bearing, a thorough inspection is necessary. This section outlines the steps you can take to diagnose the issue and explore potential solutions.
Inspecting the Wheel Bearing Assembly
Begin by visually inspecting the wheel bearing assembly. Look for signs of damage, such as cracks, leaks, or corrosion.
Checking for Play in the Wheel
As mentioned earlier, grab the wheel at the 12 and 6 o’clock positions and try to rock it. Any noticeable play indicates a worn bearing. This is a strong indicator that replacement is necessary.
Understanding the Role of the Hub Assembly
The wheel bearing in a 2018 F150 is typically integrated into a hub assembly. This means that replacing the bearing usually involves replacing the entire hub assembly. This makes the job easier but also slightly more expensive.
Consider the Cost of Replacement
Weigh the cost of replacing the wheel bearing yourself versus having a professional do it. Consider your skill level, available tools, and the potential for complications. The parts themselves aren’t overly expensive, but the labor can add up quickly at a shop. For example, a quality aftermarket hub assembly for a 2018 F150 can range from $100 to $300 per side.
Beyond the typical symptoms and inspection methods, there are some less obvious factors that can impact the lifespan of your 2018 F150’s front wheel bearings. My personal experience working on these trucks has revealed some valuable insights.
The Impact of Aggressive Driving and Off-Roading
If you frequently engage in aggressive driving or off-roading, your wheel bearings will likely wear out faster. The increased stress and impacts can accelerate bearing wear. I’ve seen many F150s with prematurely failed wheel bearings due to heavy off-road use. Consider upgrading to heavy-duty wheel bearings if you frequently subject your truck to demanding conditions.
Over-Torquing Lug Nuts: A Silent Killer
One often overlooked factor is over-torquing the lug nuts. Over-tightening can put undue stress on the wheel bearings, leading to premature failure. Always use a torque wrench and tighten the lug nuts to the manufacturer’s specified torque. Refer to your owner’s manual or a reliable source for the correct torque specifications. I’ve witnessed this issue firsthand, and it’s a simple mistake that can have costly consequences.
The Importance of Proper Installation
Even high-quality wheel bearings can fail prematurely if not installed correctly. Make sure the hub is properly seated and that all components are correctly aligned. Using a wheel bearing installation tool can help ensure proper installation and prevent damage.
Personal Opinion: Go Aftermarket (Sometimes)
While OEM parts are generally recommended, there are instances where aftermarket wheel bearings can be a better option. Certain aftermarket brands offer improved materials and designs that can enhance durability, especially for trucks that are used for towing or off-roading. Do your research and read reviews before making a decision.
Scenario-Based Advice
Imagine you’re on a road trip and start hearing a humming noise from your front end. Instead of panicking, pull over safely and check for any obvious signs of damage. If you can limp the truck to a reputable shop, do so. If not, call for roadside assistance.
I’ve been working on Ford trucks for over 15 years, and I’ve seen firsthand the common issues that affect these vehicles. My expertise comes from years of practical experience and a deep understanding of automotive mechanics.
