This process outlines the general steps. Always consult a repair manual specific to your 2000 Ford Focus for detailed instructions, torque specifications, and diagrams relevant to your exact model and trim level. Variations exist between models.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safety. Never work under a car supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Impact wrench (recommended): Makes removing the axle nut much easier. A breaker bar and a lot of leverage can also work, but it's harder.
* Socket set: Various sizes, including the correct size for the axle nut.
* Hammer and punch: For driving out parts.
* Pry bar: May be needed to separate components.
* Penetrating oil (like PB Blaster): Helps loosen rusted or stuck bolts.
* New rear wheel bearing: Get the correct part number for your car.
* Bearing packing grease: Specialized grease for wheel bearings.
* Torque wrench: Crucial for tightening bolts to the correct specification to prevent damage.
* C-clamp (possibly): May be needed to compress the bearing during installation.
* Clean rags: To keep everything clean.
General Steps (Consult your repair manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels.
2. Remove the Wheel: Loosen the lug nuts before jacking up the car. Jack up the car securely and place it on jack stands. Remove the wheel.
3. Remove the Brake Caliper: Depending on the model, you might need to remove the caliper assembly, usually by removing a bolt or two. Support the caliper with a bungee cord or wire to keep it from hanging by the brake line.
4. Remove the Rotor: Remove the rotor. This may require unscrewing it or using a puller depending on the design.
5. Remove the Axle Nut: This is often a very large nut. Use your impact wrench or breaker bar to remove it. This nut is usually very tight, be prepared for resistance.
6. Remove the Axle Flange: This might require separating the axle from the hub assembly. This step is model-dependent and can vary significantly. The repair manual will show you how the parts are assembled.
7. Remove the Old Bearing: This is often pressed into the hub assembly. You might need a bearing removal tool to carefully remove it without damage.
8. Install the New Bearing: Carefully press the new bearing into the hub assembly, ensuring it's seated correctly. You might need a press or a socket the right size to install it.
9. Reassemble Everything: Reverse the disassembly process, paying close attention to proper alignment and torque specifications. Use new axle nut if necessary.
10. Torque Specifications: Use your torque wrench to tighten all bolts to the manufacturer's specified torque values. This is crucial for proper function and safety.
11. Pack with Grease: Properly lubricate the new bearing according to the instructions on the grease packaging.
12. Test Drive: Test drive the vehicle and listen for any unusual noises. If you hear any grinding or rumbling, it's possible the bearing wasn't installed correctly.
Important Considerations:
* Hub Assembly Replacement: Sometimes, it's easier and more cost-effective to replace the entire hub assembly instead of just the bearing. This eliminates the risk of damaging the hub during bearing removal.
* ABS Sensor: The ABS sensor might be mounted on the hub. Be careful not to damage it during the process.
* Torque Specs: Incorrect torque can lead to premature failure or damage. Absolutely follow the repair manual's torque specifications.
This is a simplified overview. A detailed repair manual specific to your 2000 Ford Focus is absolutely essential. Improperly installing wheel bearings can lead to serious safety issues. If you're unsure about any step, seek professional help.
