Here's a general overview of the steps involved. Remember, this is not a complete guide and should not be used as a substitute for a proper repair manual. Improperly completing this repair can lead to dangerous driving conditions.
Tools You'll Likely Need:
* Jack and jack stands: 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.
* Torque wrench: Crucial for tightening bolts to the correct specifications.
* Socket set: Various sizes will be needed.
* Hammer and punch: Possibly for stubborn parts.
* Penetrating oil (like PB Blaster): To help loosen rusted or seized bolts.
* C-clamp or other hub nut removal tool: The hub nut is often very tight.
* New wheel hub assembly: Make sure you get the correct part for your vehicle.
* Pry bar (possibly): May be needed to separate components.
* Clean rags: To keep things clean.
* Safety glasses and gloves: Protect yourself from injury.
General Steps (Consult your repair manual for specific details):
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels.
2. Raise and Secure: Safely lift the vehicle using the jack and place it securely on jack stands.
3. Remove Wheel: Remove the lug nuts and carefully remove the wheel.
4. Brake Caliper Removal: You'll likely need to remove or at least support the brake caliper to access the hub assembly. This usually involves removing caliper mounting bolts and potentially supporting the caliper with a wire or bungee cord to keep it from hanging by the brake line.
5. Rotor Removal: The rotor might need to be removed to access the hub assembly. This usually involves removing the rotor mounting bolts.
6. Hub Nut Removal: This is often the most challenging part. The nut is typically very tight and requires a significant amount of torque to remove. A breaker bar or impact wrench may be necessary. Use a hub nut removal tool to avoid damaging the nut or hub.
7. ABS Sensor Removal (if applicable): Carefully disconnect and remove the ABS sensor if present.
8. Hub Removal: Once the nut is removed, the hub assembly should be able to be removed. This may require some gentle persuasion with a pry bar (use caution not to damage surrounding components).
9. Installation: Install the new hub assembly in reverse order of removal. Make sure to align any splines and ensure everything seats correctly.
10. Tightening: Tighten all bolts and nuts to the manufacturer's specified torque values (found in your repair manual).
11. Reassembly: Reinstall the rotor, brake caliper, and wheel.
12. Lower Vehicle: Carefully lower the vehicle and remove the jack stands.
13. Torque Check: After driving a short distance, re-check the torque on all fasteners.
Important Considerations:
* ABS Sensor: Be very careful with the ABS sensor; damage to it can cause ABS system issues.
* Torque Specifications: Using the correct torque specifications is critical for safety and longevity of the components.
* Wheel Bearings: Inspect the wheel bearings during the repair. If they're damaged or worn, they should be replaced at the same time.
Again, this is a simplified overview. A detailed repair manual is absolutely necessary for a successful and safe repair. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. This job done incorrectly can lead to serious safety hazards.
