Here's a general outline of the process. Specific steps and tools may vary slightly depending on your exact Escape model (and whether it's a hub assembly or separate bearing). Always consult a repair manual specific to your vehicle year and model for detailed instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safe lifting. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Impact wrench (highly recommended): Makes removing the hub nut much easier. If you don't have one, a breaker bar and plenty of leverage will be needed.
* Sockets and wrenches (various sizes): Consult your repair manual for specifics.
* Ball joint separator: To separate the ball joint from the steering knuckle.
* Tie rod end separator: To separate the tie rod end from the steering knuckle.
* Brake caliper compression tool: To compress the brake caliper piston.
* Hammer and punch (possibly): For stubborn components.
* Torque wrench: Crucial for proper tightening of bolts and nuts to prevent damage.
* Penetrating oil (like PB Blaster): To help loosen rusted or seized bolts.
* New wheel bearing (and possibly hub assembly): This is usually sold as a complete unit.
* Wheel bearing grease: If it's a separate bearing and not a pre-greased assembly.
* Clean rags and shop towels
General Steps (Consult your repair manual for precise details and torque specs):
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Wear safety glasses.
2. Remove the Wheel: Loosen the lug nuts slightly before jacking up the vehicle. Then, fully remove the nuts and take off the wheel.
3. Remove the Brake Caliper: Use the caliper compression tool to retract the brake caliper piston. Then, carefully remove the caliper and hang it out of the way using a wire or bungee cord. Do not let the brake line hang freely.
4. Disconnect the Ball Joint and Tie Rod End: Use the appropriate separators to carefully separate the ball joint and tie rod end from the steering knuckle. These are often the most challenging parts of the job. Penetrating oil beforehand is highly recommended.
5. Remove the Hub Nut: This is typically very tight. An impact wrench is highly recommended here. If you're using a breaker bar, brace yourself – it requires significant force.
6. Remove the Rotor (if applicable): On some models, the rotor is part of the hub assembly; on others it's separate. Consult your repair manual.
7. Remove the Hub Assembly (or Bearing): Once the hub nut is off, the hub assembly (often containing the bearing) should come off relatively easily. It may require some gentle persuasion with a hammer and punch. Take note of the position and orientation of any components before removing them.
8. Install the New Wheel Bearing/Hub Assembly: Apply new grease if necessary (check your repair manual). Install the new assembly, making sure everything is properly aligned.
9. Reassemble Everything: Carefully reassemble the components in the reverse order of disassembly. Ensure that all components are correctly aligned.
10. Tighten Everything to Spec: Use your torque wrench to tighten all bolts and nuts to the manufacturer's specifications found in your repair manual. This is crucial to avoid damage and ensure safety.
11. Test Drive: After reassembly, carefully test drive the vehicle to make sure everything is working correctly. Listen for any unusual noises.
Important Considerations:
* Hub Assembly vs. Separate Bearing: Some 2004 Ford Escapes use a complete hub assembly that includes the bearing. Replacing this is easier. Others might have a separate bearing that needs to be pressed in and out. This requires specialized tools and knowledge.
* ABS Sensor: The ABS (Anti-lock Braking System) sensor may be attached to the hub assembly. Handle it with care and make sure to reconnect it properly.
* Torque Specifications: Using the correct torque specifications is crucial to prevent damage and ensure safety. Never guess – always consult your repair manual.
Again, this is a general overview. Consult a repair manual specific to your vehicle for detailed instructions and torque specifications. If you are not comfortable with this level of repair, take your Escape to a qualified mechanic. Improper repair can lead to serious safety hazards.
