A Ford Excursion Owner's Guide to Front Hub and Rotor Replacement (2000-2005)
Eliminate brake vibrations and wheel bearing noise on your heavy-duty Excursion by choosing the right parts.
- Verify if your Excursion is 4WD or 2WD before ordering; the front hub parts are different.
- Symptoms include humming noises that increase with speed and vibrations when braking.
- Always replace front hub assemblies and rotors in pairs to ensure safety and performance.
- For a heavy truck like the Excursion, investing in a premium brand like Timken is recommended over budget options.
Understanding Your Excursion's Front Brakes
Before buying parts, it's important to know how your truck is built. The 2000-2005 Ford Excursion uses two different front-end setups.
- 4-Wheel Drive (4WD/4x4): These models use a separate Wheel Hub & Bearing Assembly and a Disc Brake Rotor that mounts to it. This guide focuses on this common setup. The hub assembly is a single, non-serviceable unit that gets replaced entirely.
- 2-Wheel Drive (2WD/RWD): These models often use a combined Rotor and Hub Assembly where the rotor and hub are one piece. The bearings are typically separate and serviceable.
Symptoms of a Failing Hub Assembly or Warped Rotor
Because these parts work together, their failure symptoms can be related. You will likely need to replace both the hub assemblies and the brake rotors at the same time.
- Humming or Roaring Noise: A steady humming, roaring, or grinding noise that gets louder with vehicle speed is the most common sign of a bad wheel bearing inside the hub assembly. The noise may change pitch when you turn left or right.
- Vibration or Pulsating Brake Pedal: If you feel a pulsing in the brake pedal or a vibration in the steering wheel specifically when braking, your brake rotors are likely warped. This is a very common issue on heavy trucks like the Excursion.
- Clicking Sounds: A clicking noise from the wheel area, especially when turning or hitting bumps, can point to a failing bearing or issues with the locking hub mechanism.
- Loose Wheel: If the vehicle is jacked up, you may be able to feel play by grabbing the tire at the top and bottom and trying to wiggle it. Any movement indicates a severely worn bearing.
- ABS Light: The ABS sensor reads a tone ring on the hub assembly. A failing bearing can damage the sensor or ring, triggering the ABS warning light on your dash.
Choosing the Right Aftermarket Parts
For a vehicle of this age, quality aftermarket parts are the standard. Original Ford parts can be expensive and hard to find. The key is to choose a reputable brand, as cheap, unbranded hubs often fail quickly on a heavy vehicle like the Excursion.
Brand Quality Tiers
Here’s how the available brands generally stack up for this truck:
- Premium (Best for Durability & Towing): Brands like Timken are widely considered the top-tier choice, often matching or exceeding original equipment quality. They are built for heavy-duty use and are a smart investment if you plan to keep your Excursion for a long time or use it for towing.
- Daily Driver (Good Quality & Value): Raybestos, Centric, and Bendix fall into this category. They offer a good balance of price and performance for normal driving. Some mechanics note that Centric parts can have a better finish than other brands in this tier. Raybestos and Bendix often market "Severe Duty" lines that are a solid choice.
- Economy (Budget-Focused): Brands like Pronto are designed to be an affordable solution. While they meet basic requirements, their lifespan may be shorter under the heavy loads an Excursion produces. These are best for a truck that is driven lightly or if you're on a tight budget.
Estimated Costs for Replacement
Costs can vary based on brand and your local shop's labor rates. The table below provides a general estimate.
| Part/Service | Estimated Cost (Per Axle) |
|---|---|
| New Aftermarket Hub Assemblies (Pair) | $260 - $640 |

Frequently Asked Questions (FAQ)
Do I have to replace the whole assembly or can I just replace the bearing?
For 4WD models, the front hub and bearing is a single, sealed unit. It is not designed to be taken apart. The entire assembly must be replaced when the bearing fails.
My 4-wheel drive isn't working. Could it be related to the hubs?
Yes. The 2000-2005 Excursion uses a vacuum-operated system to lock the front hubs for 4WD. The vacuum seals in the hub assembly can fail, causing a leak that prevents the 4WD from engaging. Many owners with failed vacuum hubs choose to install aftermarket manual-locking hubs for better reliability.
What is the brake-related fire recall I've heard about?
This is a separate but critical issue. NHTSA recall 09V399000 affects 2000-2003 Excursions. The cruise control deactivation switch on the brake master cylinder can leak fluid and cause a fire, even when the truck is parked and off. Check if your vehicle has had the recall service performed. The fix involves a fused wiring harness. If the switch is leaking, it must be replaced immediately.
Can I reuse my old brake rotors?
It is not recommended. If your hub assembly has failed, there's a high chance the heat and vibration have affected the rotors. Given the heavy weight of the Excursion, installing new, high-quality rotors with your new hubs is the best practice to ensure smooth, safe braking.
