However, if you're determined to do it yourself, here's a general outline. This is not a comprehensive guide and should not be considered a substitute for a proper repair manual specific to your Expedition's year and model. Always consult your vehicle's repair manual for precise instructions and torque specifications.
Tools You'll Likely Need:
* Jack and Jack Stands: Absolutely essential for safety.
* Wheel Chocks: To prevent the vehicle from rolling.
* Lug Wrench: To remove the wheel.
* Torque Wrench: Crucial for proper tightening of bolts.
* Hammer and Punch: Possibly needed for removing components.
* Sockets and Wrenches: Various sizes depending on your Expedition.
* Pry Bar: May be needed to separate components.
* Bearing Removal and Installation Tool: This is absolutely necessary. You'll need a press or puller specifically designed for wheel bearings. Improvising can damage the hub and bearing.
* Clean rags and shop towels: To keep things clean and prevent contamination.
* Penetrating Oil (PB Blaster or similar): To help loosen rusted or seized components.
* New Wheel Bearing (and possibly a new seal): Ensure you get the correct part for your vehicle's year, model, and axle configuration.
General Steps (This is a simplified overview – refer to your repair manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Raise the vehicle securely using the jack and place it on jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Brake Caliper and Rotor: This process varies depending on your year and model. You'll likely need to disconnect the brake line, support the caliper, and then remove the rotor.
4. Disconnect the Axle Components: This is where it gets more complex. You'll need to disconnect various components connecting the axle to the hub assembly. This often involves removing cotter pins, nuts, and potentially other fasteners. Refer to your repair manual for the exact sequence.
5. Remove the Hub Assembly: This often requires significant force and the correct tools. You may need to use a puller to separate the hub from the knuckle.
6. Press Out the Old Bearing: Use your bearing removal tool to carefully press out the old bearing from the hub assembly.
7. Press In the New Bearing: Use your bearing installation tool to carefully press the new bearing into the hub assembly. Ensure it's seated properly.
8. Reassemble: Carefully reassemble all the components in the reverse order of removal. Pay close attention to the correct orientation of all parts.
9. Torque Specifications: Use your torque wrench to tighten all bolts and nuts to the manufacturer's specified torque values. This is critical for safety.
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Test Drive: After reassembly, test drive the vehicle to ensure the bearing is functioning correctly. Listen for any unusual noises.
Again, this is a highly simplified overview. Replacing a wheel bearing is a significant undertaking that requires precision and the right tools. Failure to do it correctly could result in serious damage or injury. Consult a repair manual specific to your Ford Expedition and if you are not confident in your abilities, seek professional help.
