Here's a general overview, but remember this is NOT a complete guide and should be supplemented with a proper repair manual:
Tools You'll Likely Need:
* Wheel chocks: Essential for safety.
* Jack and jack stands: Never work under a car supported only by a jack.
* Lug wrench: To remove the wheel.
* Torque wrench: Crucial for tightening bolts to the correct specification.
* Socket set: Various sizes, likely including metric sizes.
* Hammer and punch: Possibly needed to remove parts.
* Pry bar: Might be helpful for separating components.
* Penetrating oil (like PB Blaster): To help loosen rusted or seized bolts.
* New rear wheel bearing: Make sure you get the correct one for your Mondeo.
* Bearing race and seal installer/remover tools: These are specialized tools that can make the job much easier and prevent damage. Improvising can damage the new bearing.
* Clean rags or shop towels: To keep things clean.
* Safety glasses and gloves: Always recommended when working on a car.
General Steps (Consult your repair manual for precise details):
1. Safety First: Engage the parking brake, chock the front wheels, and jack up the rear of the car securely using jack stands.
2. Remove the Wheel: Loosen the lug nuts before jacking up the car. Remove the wheel.
3. Remove the Brake Caliper and Rotor: This usually involves removing the caliper mounting bolts, carefully hanging the caliper out of the way (use a wire or bungee cord to keep it from hanging by the brake hose), and then removing the rotor (sometimes it's held on by a single bolt or just friction, check your manual).
4. Remove the Hub Nut and Axle Nut: This is often a large nut, requiring significant torque to loosen. You might need a breaker bar.
5. Remove the Axle Flange (potentially): Depending on the Mondeo's design, you might need to remove the axle flange to access the bearing.
6. Remove the Old Bearing: This is where the specialized tools are crucial. You'll likely need to carefully press out the old bearing and races without damaging the hub or axle.
7. Install the New Bearing: Again, specialized tools are highly recommended to install the new bearing and races correctly and evenly, avoiding damage.
8. Reassemble Everything: Carefully reverse the steps, ensuring everything is properly aligned and tightened to the correct torque specifications (consult your repair manual). This includes the axle nut, hub nut, rotor, caliper, and wheel.
9. Lower the Car and Check: Lower the car carefully and check that the wheel rotates freely and there's no play or noise.
Important Notes:
* This is a simplified overview. The specific procedures and components may vary depending on the exact model and year of your Mondeo.
* Incorrect installation can lead to serious consequences. A poorly fitted bearing can fail, leading to loss of control and accidents.
* Use a repair manual specific to your car. The manual will provide precise instructions, torque specifications, and diagrams to guide you through the process safely and effectively.
* If you're not comfortable with this level of car repair, it's best to take it to a qualified mechanic. The cost of professional repair is much less than the potential cost of a mistake.
