So, your 2015 F150 is making that telltale hum, growl, or even a clicking sound that gets louder with speed. Chances are, it’s a wheel bearing. Replacing it yourself can save you a bundle, but it’s more than just unbolting and bolting. This article digs into the real-world challenges of a 2015 F150 wheel bearing replacement, including some common pitfalls that can turn a simple job into a weekend-long headache. We’ll cover the process, but more importantly, we’ll equip you with the knowledge to avoid common mistakes and get the job done right the first time.
Before you even think about ordering a new wheel bearing, it’s crucial to accurately diagnose the problem. Many noises can mimic a bad wheel bearing.
- Listen Carefully: Pay attention to when the noise occurs. Does it change with speed? Does it disappear when you turn one way or the other? Load on the bearing changes during turns, providing a clue.
- Visual Inspection: Jack up the truck and spin the wheel. Listen and feel for roughness or grinding. Grab the wheel at the 12 and 6 o’clock positions and try to rock it back and forth. Excessive play indicates a worn bearing. Also, inspect the bearing area for any grease leaks.
- The “Other” Suspects: Don’t immediately jump to wheel bearings. Worn tires, especially those with aggressive tread patterns, can generate significant road noise. Check your tires for uneven wear or cupping. Also, inspect your brakes. A dragging brake pad can create noise and heat that mimics a bad bearing. And on 4×4 models, don’t forget to check your front differential fluid level. A low fluid level can cause noise in the front-end that sounds like a bad wheel bearing.
Okay, you’ve confirmed it’s a wheel bearing. Here’s the process, but with a focus on avoiding common mistakes:
- Gather Your Tools: You’ll need a jack, jack stands, lug wrench, socket set, breaker bar, torque wrench, penetrating oil, a hammer, a punch, and potentially a wheel bearing removal tool. Don’t skimp on quality tools! Cheaping out here can lead to stripped bolts and frustration.
- Loosen the Axle Nut: This is critical and often overlooked. While the wheel is still on the ground (and the vehicle in park with the emergency brake engaged), use a breaker bar and socket to loosen the axle nut. It’s usually incredibly tight. Soaking it with penetrating oil the night before helps.
- Raise and Secure the Truck: Jack up the truck and securely support it with jack stands. Never work under a vehicle supported only by a jack!
- Remove the Wheel and Brake Components: Remove the wheel, caliper (don’t let it hang by the brake hose – support it with a bungee cord), and brake rotor.
- Remove the Hub/Bearing Assembly: This is where things can get tricky. The hub/bearing assembly is often rusted in place. Use penetrating oil liberally and let it soak. A slide hammer with a hub attachment can be a lifesaver. If you don’t have one, you can try tapping the hub from behind with a hammer and punch, being careful not to damage anything.
- Clean and Inspect: Once the old bearing is out, clean the hub mounting surface thoroughly. Inspect the surrounding components for any damage or wear.
- Install the New Bearing: This is crucial: Ensure the bearing is properly seated in the hub. Use a wheel bearing installation tool to press the new bearing into the hub. Never hammer it in! This can damage the bearing. Apply a thin layer of anti-seize to the hub mounting surface before reinstallation.
- Reassemble Everything: Reinstall the hub/bearing assembly, brake rotor, caliper, and wheel. Torque everything to the manufacturer’s specifications. Don’t guess on torque specs!
- Torque the Axle Nut: With the wheel on the ground, torque the axle nut to the correct specification. This is a critical step. An improperly torqued axle nut can lead to premature bearing failure.
- Test Drive: Take the truck for a test drive and listen for any unusual noises.
The One Tool You Should Buy: A Quality Torque Wrench
I can’t stress this enough. While many jobs allow for “close enough”, wheel bearings demand precision. Investing in a good quality torque wrench (both a low-range and a high-range) is essential. Over-torquing can damage the bearing or the surrounding components. Under-torquing can lead to premature failure and potential safety issues. Don’t risk it.
While saving money is always a good idea, the wheel bearing is not the place to cut corners. Cheap aftermarket bearings are notorious for early failure. Invest in a quality bearing from a reputable brand like Timken or SKF. The extra cost is worth it in the long run.
I learned this lesson the hard way. I installed a cheap bearing on my own F150 to save a few bucks. It lasted less than a year before I had to replace it again. The second time, I went with a Timken bearing, and it’s been going strong for years. Sometimes the upfront cost is worth avoiding the hassle of doing the job twice.
Okay, maybe it’s just me, but I swear I noticed a slight bump in fuel economy after replacing my wheel bearings. A worn bearing creates friction, which translates to wasted energy. A fresh, properly lubricated bearing reduces friction, allowing the wheel to spin more freely. Don’t expect miracles, but every little bit helps!
Dealerships make a lot of money on wheel bearing replacements. The labor costs are significant, and they often mark up the price of the parts. By doing it yourself, you can save hundreds of dollars. This also puts you in control of the parts used – you can choose a high-quality bearing instead of settling for whatever the dealership has on hand.
| Component | Estimated Cost (DIY) | Estimated Cost (Dealership) |
|---|---|---|
| Wheel Bearing | $80 – $200 | $150 – $300 |
| Labor | $0 | $200 – $400 |
| Total | $80 – $200 | $350 – $700 |
These are estimated costs and can vary depending on the specific parts used, your location, and the dealership’s labor rates.
One thing often overlooked is the ABS sensor. The ABS sensor is usually integrated into the wheel bearing assembly. When replacing the bearing, be extremely careful not to damage the sensor. Also, ensure the new bearing assembly comes with a compatible ABS sensor. If your ABS light comes on after the replacement, double-check the sensor connection and wiring. A damaged or improperly connected ABS sensor will trigger the light.
