Tools You'll Likely Need:
* Repair Manual: Absolutely essential for specific torque specifications, component locations, and procedures.
* Jack and Jack Stands: Securely support the vehicle. Never work under a vehicle supported only by a jack.
* Wheel Chocks: To prevent the vehicle from rolling.
* Lug Wrench: To remove the wheel.
* Wheel Hub Socket/Puller: May be needed to remove the hub assembly.
* Hammer and Punch: Possibly to help separate components.
* Torque Wrench: Absolutely critical for proper tightening of bolts and nuts.
* Socket Set and Wrenches: Various sizes will be needed.
* Penetrating Oil (PB Blaster, etc.): To help loosen rusted or seized bolts.
* Grease: For the new bearing.
* New Wheel Bearings: Ensure you purchase the correct bearings for your vehicle. Often sold as a complete hub assembly.
* Clean Rags: To keep things clean.
* Safety Glasses and Gloves: Protect yourself.
General Steps (Consult your repair manual for precise instructions):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks.
2. Raise and Support the Vehicle: Safely lift the vehicle using a jack and secure it on jack stands.
3. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
4. Remove the Brake Caliper: Unbolt the caliper and carefully hang it out of the way using a bungee cord or wire to avoid putting stress on the brake line.
5. Remove the Rotor: Remove the brake rotor. It may be necessary to use a rotor puller if it's stuck.
6. Remove the Hub Assembly: This is where it gets tricky. You'll likely need to remove cotter pins, castle nuts, and possibly use a hub puller to separate the hub assembly from the spindle. Your repair manual will have detailed diagrams and instructions for this step. Pay close attention to the order and location of components.
7. Remove the Old Bearing: Once the hub assembly is removed, the old bearing should be easily accessible. It may require a bearing puller or gentle persuasion to remove it.
8. Install the New Bearing: Carefully install the new bearing into the hub assembly. Ensure the bearing is seated correctly and without damage.
9. Reassemble: Reverse the disassembly steps, carefully reinstalling the hub assembly, rotor, caliper, and wheel. Pay close attention to torque specifications for all bolts and nuts found in your repair manual.
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Test Drive: After reassembly, perform a test drive to check for any noises or vibrations indicating a problem.
Important Considerations:
* ABS Sensors: If your Avenger has Anti-lock Brakes (ABS), you'll need to be very careful with the ABS sensor wire during disassembly and reassembly. Damage to this sensor can cause ABS malfunctions.
* Torque Specifications: Using the correct torque specifications is crucial to avoid damage to the components and ensure proper function. Always refer to your repair manual.
* Professional Help: If you are not comfortable performing this repair, it's best to take your vehicle to a qualified mechanic. Incorrect installation can lead to serious safety hazards.
This guide provides a general overview. Always consult your vehicle's repair manual for the specific procedures and torque specifications. Attempting this repair without the proper knowledge and tools could damage your vehicle or cause injury.
