Here's a general overview of the process. This is NOT a substitute for a proper repair manual:
Tools You'll Likely Need:
* Jack and jack stands: Absolutely essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Socket set and wrenches: Various sizes will be needed, depending on the specific nuts and bolts.
* Hammer and punch: Possibly for removing components.
* Bearing race and seal installer/remover: Specialized tools to avoid damaging the bearing races and seals. Improper installation can ruin new bearings.
* Torque wrench: Crucial for tightening bolts to the manufacturer's specifications.
* Penetrating oil: To help loosen rusted or seized components.
* Clean rags and shop towels: To keep things clean and prevent contamination.
* Grease: For repacking the new bearing.
General Steps (Consult your repair manual for specifics):
1. Safety First: Secure the vehicle with jack stands and wheel chocks. Engage the parking brake.
2. Remove the Wheel: Loosen the lug nuts, jack up the vehicle, secure it on jack stands, and remove the wheel.
3. Remove the Brake Caliper and Rotor: Depending on your Escape's configuration, you might need to remove the brake caliper (usually with a caliper bracket bolt) and the rotor. Support the caliper with a wire or bungee cord to prevent it from hanging by the brake line.
4. Remove the Axle Nut: This nut is usually very tight. Use a breaker bar if necessary. Note the position of the nut relative to the axle flange before removal to aid reassembly.
5. Remove the Axle Flange: This might require separating the axle from the differential. This step often requires specialized tools and a lot of care. The axle nut likely holds the axle flange in place.
6. Remove the Old Bearing: This is where the bearing race and seal installer/remover tools are vital. The bearing and races are usually pressed into place, so force is needed for removal. Damage to the hub during this process is common if improper tools are used.
7. Clean the Hub: Thoroughly clean the hub assembly to remove any old grease, dirt, and debris.
8. Install the New Bearing and Seal: Use the correct tools to press the new bearing and seal into the hub, ensuring proper alignment.
9. Reassemble Everything: Carefully reverse the disassembly steps, ensuring everything is correctly aligned and tightened to the specified torque. Pay close attention to the axle nut torque.
10. Refill the differential with gear oil (if necessary): Depending on whether you removed the axle from the differential housing you may need to add oil.
11. Test Drive: After reassembly, test drive the vehicle to ensure the bearing is operating smoothly and quietly.
Important Considerations:
* ABS Sensor: The ABS sensor may be located near the wheel bearing. Handle it with care during the process.
* Torque Specifications: Using the correct torque is absolutely critical to prevent damage and ensure safety.
* Wheel Bearing Type: The type of wheel bearing (e.g., sealed unit or serviceable) will dictate the repair process.
This is a simplified overview. Failure to follow the correct procedures can result in damage to your vehicle and potential injury. It's strongly advised to consult a repair manual specific to your 2003 Ford Escape or take it to a qualified mechanic. The potential cost of repairing damage from incorrect installation far outweighs the cost of obtaining a repair manual or professional service.
