Here's a general overview of the steps involved. This is not a complete guide and should not be taken as definitive instructions. Always refer to your 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.
* Socket set and wrenches: Various sizes will be needed, depending on your specific Aveo.
* Hammer and punch (or drift punch): For removing and installing the bearing.
* Bearing race and seal installer/remover: Highly recommended to avoid damaging the new bearing. These tools are specialized and may require purchase or rental.
* Torque wrench: Crucial for tightening bolts to the correct specification. Improper torque can damage components.
* Penetrating oil (like PB Blaster): To help loosen rusted or seized parts.
* Grease: For repacking the new bearing.
* New rear wheel bearings and seals: Make sure you get the correct parts for your Aveo's year and model.
General Steps (Again, consult your repair manual):
1. Safety First: Park the car on a level surface, engage the parking brake, and use wheel chocks on the wheels that are *not* being worked on. Raise the car safely using a jack and secure it on jack stands.
2. Remove the Wheel: Loosen the lug nuts before jacking up the car. Remove the wheel.
3. Remove the Brake Drum or Rotor: This will vary depending on your Aveo model. Some have drum brakes, others have disc brakes. You may need to remove brake caliper (disc brakes) or brake shoes (drum brakes). This often requires removing bolts and possibly disconnecting brake lines (be careful with brake fluid!).
4. Remove the Axle Nut (and possibly the axle flange): This will be a large nut securing the wheel hub to the axle. It's often very tight. Use a breaker bar if necessary.
5. Remove the Hub Assembly: This will vary depending on the Aveo's design. You might need to separate the hub assembly from the axle flange.
6. Press Out the Old Bearing: This is where specialized tools are crucial to avoid damaging the new bearing. The old bearing will likely be pressed into the hub assembly.
7. Press In the New Bearing: Again, specialized tools are necessary here. Make sure the new bearing is properly seated.
8. Install New Seal(s): Replace the old seals with new ones.
9. Reassemble Everything: Carefully reverse the disassembly steps, ensuring everything is properly aligned and tightened to the correct torque specifications (consult your repair manual). Lubricate as needed.
10. Torque Specifications: Use a torque wrench to tighten all bolts and nuts to the manufacturer's specifications. This is crucial to prevent damage and ensure safe operation.
11. Test: Lower the car, and carefully test drive the vehicle, checking for unusual noises or vibrations.
Important Considerations:
* Repair Manual: Investing in a repair manual specific to your Aveo is highly recommended. It will provide detailed instructions and diagrams.
* Safety: Working on your car can be dangerous. If you are not comfortable performing this repair, take your Aveo to a qualified mechanic.
* Parts: Ensure you're using the correct parts for your specific vehicle.
* Torque Specifications: Adhering to the correct torque specifications is critical for safe and proper operation.
This is a simplified overview. The actual process can be considerably more complex, depending on your Aveo's year and model. Do not attempt this repair without consulting a detailed repair manual. If you're unsure about any step, seek professional help. Improperly installed wheel bearings can be extremely dangerous.
