How do you change the front wheel bearing on a Ford Falcon AU?

Replacing a front wheel bearing on a Ford Falcon AU is a moderately difficult job requiring some mechanical aptitude and the right tools. It's not a beginner's task. If you're not comfortable working on cars, it's strongly recommended to take it to a qualified mechanic. Improperly installed bearings can lead to serious safety issues.

That being said, here's a general overview of the process. This is NOT a complete, step-by-step guide and should not be considered a substitute for a proper workshop manual specific to your year and model of Ford Falcon AU. Variations exist between model years.

Tools you'll likely need:

* Wheel chocks: Essential for safety.

* Jack and jack stands: Properly support the vehicle.

* Lug wrench: To remove the wheel.

* Socket set and ratchet: Various sizes, including those for the hub nuts and caliper bolts.

* Torque wrench: Crucial for tightening components to the correct specification.

* Hammer and punch (or drift): May be needed to remove components.

* Press or bearing puller: Almost certainly necessary for removing the old bearing. A press is far superior.

* New front wheel bearing: Ensure you get the correct part for your vehicle.

* Grease: High-quality wheel bearing grease.

* Penetrating oil: To help loosen seized components.

* Clean rags: To keep things clean.

* Workshop manual: Absolutely essential for your specific model year Falcon AU. This will have the correct torque settings, diagrams, and specific procedures.

General Steps (Consult your workshop manual for detailed instructions):

1. Safety First: Secure the vehicle with wheel chocks and use a jack and jack stands to lift the front end safely.

2. Remove the Wheel: Remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper: Remove the caliper bolts and carefully support the caliper to prevent damage to the brake hose. You might need to use a cable tie or hang it from the suspension.

4. Remove the Rotor (Disc Brake): Remove the rotor retaining bolts (if present). Sometimes these can be stubborn.

5. Disconnect the ABS Sensor (if applicable): Carefully disconnect the ABS sensor wire from the hub.

6. Remove the Hub Nut: This will be a large nut. It's usually very tight; use a breaker bar if necessary.

7. Remove the Hub Assembly: This step often requires the use of a puller to separate the hub assembly from the steering knuckle.

8. Remove the Old Bearing: This is where a bearing press or puller is essential. Trying to hammer it out will likely damage the bearing and/or the hub.

9. Install the New Bearing: Using a press, carefully install the new bearing into the hub assembly. Ensure it seats correctly.

10. Grease the Bearing: Pack the new bearing liberally with high-quality wheel bearing grease.

11. Reassemble Everything: Reassemble the hub assembly, rotor, caliper, wheel, and lug nuts in reverse order of removal. Use a torque wrench to tighten all components to the manufacturer's specified torque settings (found in your workshop manual).

12. Lower the Vehicle: Carefully lower the vehicle.

13. Test Drive: Test drive the vehicle to ensure the new bearing is functioning correctly. Listen for any unusual noises.

Disclaimer: This information is for general guidance only. Incorrectly performing this repair can result in serious injury or damage to your vehicle. Always consult a workshop manual specific to your Ford Falcon AU model year and seek professional assistance if you're unsure about any step. Improperly torqued components can lead to failure and serious accidents.
