However, to give you a *general* idea of the process involved (do not attempt this yourself unless you have extensive automotive experience):
1. Safety First: Disconnect the battery negative terminal. Use jack stands to securely support the vehicle, never rely solely on a jack. Wear safety glasses and gloves.
2. Remove the Wheel and Tire: Remove the wheel and tire from the affected side.
3. Disconnect Brake Components: This will include disconnecting the brake caliper, brake lines (carefully!), and possibly the ABS sensor. You'll likely need to support the caliper to prevent it from hanging by the brake line.
4. Disconnect Tie Rod End and Ball Joint: These components connect the steering and suspension to the wheel stub. Special tools are needed to separate these connections safely without damaging them.
5. Remove the Wheel Stub Assembly: This involves removing various bolts and possibly nuts securing the wheel stub to the knuckle. You may need to use a press to remove the stub.
6. Install the New Wheel Stub Assembly: This is the reverse of the removal process. Pay close attention to the correct torque specifications for all bolts and nuts. A torque wrench is essential.
7. Reconnect Brake Components, Tie Rod End, and Ball Joint: Reattach all components carefully, ensuring everything is properly aligned and secured. Bleed the brakes after reconnecting the brake lines.
8. Reinstall the Wheel and Tire: Remount the wheel and tire, and torque the lug nuts to the manufacturer's specifications.
9. Lower Vehicle and Test: Slowly lower the vehicle and test the steering and braking. Have the alignment checked by a professional afterward.
Specific tools you'll likely need:
* Jack and jack stands
* Wheel wrench
* Brake caliper compression tool
* Tie rod end separator
* Ball joint separator
* Socket set and wrenches (various sizes)
* Torque wrench
* Possibly a press
* Alignment tools (for professional alignment after the repair)
Again, this is a simplified overview. The exact procedure will vary slightly depending on the year and model of your Ford Expedition. Consult a repair manual specific to your vehicle's year and model for detailed instructions and torque specifications. Attempting this repair without the proper knowledge and tools is highly discouraged. The risks of injury and vehicle damage are significant.
