2025 Ford Expedition Hub & Bearing: Diagnosing Noise, Vibration, and ABS Faults
A complete guide to identifying bad wheel hubs on your 2025 Expedition, with torque specs and tips for buying a quality used replacement.
- The most common symptom of failure is a humming or roaring noise that gets louder with speed and may change pitch when turning.
- A failing hub can disable the ABS and traction control systems, which is a serious safety risk.
- The axle nut torque specification is critical for the lifespan of the new bearing and is typically a single-use part that must be replaced.
- Premature failure under 50,000 miles has been reported by some owners of this Expedition generation, so it's worth checking for warranty coverage.
Symptoms of a Failing Hub Assembly
A failing wheel hub on a 2025 Expedition will almost always provide audible or physical warnings. Ignoring these signs can lead to more severe damage or a dangerous loss of vehicle control.
1. Humming, Roaring, or Grinding Noise
This is the most common symptom. The noise is rotational and will increase in pitch and volume with vehicle speed. It's often described as a low hum or roar at highway speeds, which can be mistaken for aggressive tire tread noise. To help pinpoint the source, listen for changes in the noise while turning. A noise that gets louder when turning right typically indicates a failing left-side wheel bearing, as the vehicle's weight shifts and puts more load on it. Conversely, a noise that worsens on a left turn points to the right-side bearing.
2. Vibration or Wobble
As the bearing wears, it can develop excessive play, leading to a vibration or wobble felt in the steering wheel or through the floor of the vehicle. This may be subtle at first but will worsen over time, especially at highway speeds. In some cases, owners report feeling a vibration through the accelerator pedal.
3. ABS, Traction, or Stability Control Warning Lights
The wheel hub assembly houses the ABS wheel speed sensor components. If the sensor or the reluctor ring inside the hub fails or gets damaged by the failing bearing, it will trigger warning lights on the dashboard. This is a serious safety issue, as it disables these critical driver-assist systems.
4. Looseness or Play in the Wheel
A severely worn bearing will cause noticeable looseness in the wheel. To check for this, the vehicle must be safely lifted so the tire is off the ground. Grasp the tire at the 12 and 6 o'clock positions and attempt to rock it back and forth. Any detectable play or clunking sound indicates a bad wheel bearing. If play is detected, it's crucial to confirm it's not from a worn ball joint or tie rod end before condemning the hub.
Known Issues, TSBs, and Recalls for 2025 Ford Expedition
As the 2025 Expedition is part of the fourth generation (starting in 2022), data from earlier models in this generation is relevant. While there are no specific recalls for wheel hub assemblies as of mid-2026, forum discussions indicate that premature wheel bearing failure is not unheard of in this generation, with some owners reporting failures at mileages as low as 30,000 to 50,000 miles. These failures are often covered under the vehicle's powertrain warranty.
Other recalls for the 2025 Expedition and its platform-mates include:
- NHTSA Recall 25V-314: Affecting 2022-2024 Expedition and Navigator models, this recall addresses front brake lines that may rub against the engine air cleaner outlet pipe, potentially causing a brake fluid leak.
- Electronic Brake Booster Malfunction: A recall was issued for certain 2025 Expedition models where the electronic brake booster (EBB) module could malfunction, resulting in a loss of power brake assist.
- Passenger Side Air Bag: Some 2025 Expedition vehicles were recalled for a passenger side air bag that could deploy with excessive force.
While these recalls do not directly involve the hub assembly, they are important safety items for owners to be aware of.
Pro Tip: Before assuming a roaring noise is a bad wheel bearing, have your tires checked. Uneven or "chopped" tire wear can create a very similar sound to a failing bearing. A simple way to check is to rotate the tires and see if the noise moves with the tire.
Buying a Used 2025 Expedition Hub Assembly
A low-mileage, used OEM hub assembly can be a smart purchase, often providing superior quality and longevity compared to a new, low-cost aftermarket part. However, careful inspection is essential.
- Check for Smoothness: With the part in hand, try to spin the hub flange. It should rotate silently and with perfect smoothness. Any roughness, grinding, or catching sensation means the bearing is bad.
- Inspect for Play: Try to wiggle the hub flange. There should be absolutely zero play or movement between the inner and outer parts of the assembly.
- Examine the ABS Sensor and Connector: Look closely at the ABS sensor wire and its electrical connector. Ensure there is no fraying, cracking, or damage to the pins. A damaged connector can be as problematic as a bad bearing.
- Look for Physical Damage: Inspect the housing for any signs of impact from an accident or damage from improper removal (e.g., hammer marks). Check the mounting surfaces to ensure they are flat and clean.
- Verify Mileage and Compatibility: Always purchase from a reputable seller who can provide the mileage of the donor vehicle. Aim for the lowest mileage possible. Confirm the part number and whether it's for a 2WD or 4WD model, as they are different. The OEM part number for a 2025 RWD front hub is RL1Z-1104-C or Motorcraft HUB-626.
Replacement Procedures and Torque Specs
Replacing the hub assembly is a job that can be done by a skilled DIY mechanic, but it requires proper tools, including a high-quality torque wrench. The axle nut torque is especially critical for the new bearing's longevity.
Key Torque Specs (Note: These can vary. Always verify with a model-specific service manual): 🎬 Watch this step-by-step F-150 wheel hub replacement video.
| Component | Torque Spec | Notes |
|---|---|---|
| Axle Nut (Spindle Nut) | 20 ft-lbs | This spec from a forum for 2007-2019 models seems low and should be verified. F-150s of a similar era use a much higher torque, often around 30 ft-lbs initially, then backed off and retorqued. Over-torquing can destroy the new bearing. These nuts are often single-use and should be replaced. |
| Hub Mounting Bolts | 150 ft-lbs | This is for the bolts that secure the hub assembly to the knuckle. |
| Brake Caliper Bracket Bolts | 185 ft-lbs | |
| Wheel Lug Nuts | 150 ft-lbs |
Warning: The axle nut is typically a torque-to-yield design and should be replaced with a new one whenever it is removed. Reusing the old nut can result in it backing off, leading to premature bearing failure and a potential wheel separation.

Frequently Asked Questions (FAQ)
Can I drive my Expedition with a bad wheel bearing?
It is not recommended for long distances. While the vehicle may be drivable, a failing bearing can cause unpredictable handling, disable the ABS and stability control systems, and in a worst-case scenario, lead to the wheel separating from the vehicle. It should be repaired as soon as possible.
Do I need a wheel alignment after replacing a hub assembly?
A wheel alignment is generally not required after replacing only the hub assembly, as it does not typically affect alignment angles. However, if you were experiencing steering pull or uneven tire wear, or if other suspension components like control arms or tie rods were loosened or replaced, an alignment is highly recommended.
Is the front hub different from the rear hub? And 2WD vs. 4WD?
Yes, the front and rear hub assemblies are different parts and are not interchangeable. Furthermore, the front hubs for two-wheel drive (2WD) and four-wheel drive (4WD) models are different. The 4WD version is designed to accommodate the front drive axle (CV axle). It is crucial to order the correct part for your specific vehicle configuration.
Is it better to replace hubs in pairs?
While not strictly necessary, it is often a good practice. Wheel bearings on both sides of an axle experience similar wear and tear. If one has failed due to high mileage, the other may not be far behind. Replacing them in pairs can save you from having to do the same job again in the near future.
