This process outlines the general steps. Specifics may vary slightly depending on your exact model and tools available. Always consult a repair manual specific to your 2001 Oldsmobile Aurora for detailed instructions, torque specifications, and diagrams. These specifications are crucial for proper installation and preventing damage.
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 vehicle.
* Lug wrench: To remove the wheel.
* Wheel alignment tool: Essential for setting the wheel's proper angle after reassembly.
* Socket set and wrenches: Various sizes for bolts and nuts.
* Ball joint separator: To separate the ball joint from the steering knuckle.
* Tie rod end separator: To separate the tie rod end.
* Hammer and punch: May be needed for stubborn components.
* Penetrating oil (PB Blaster or similar): To loosen rusted bolts and nuts.
* Torque wrench: Crucial for tightening bolts to the manufacturer's specifications.
* Press (optional but highly recommended): For safely pressing the old bearing out and the new one in. Doing this without a press significantly increases the risk of damaging the hub.
* New wheel bearing: Ensure you get the correct part number for your specific Aurora.
* Repair manual: A must-have for detailed instructions and torque specifications.
General Steps (Consult your repair manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks.
2. Remove the Wheel: Loosen the lug nuts before jacking up the car. Raise the vehicle securely with the jack and place it on jack stands. Remove the wheel.
3. Disconnect Components:
* Brake Caliper: Carefully remove the brake caliper and hang it securely using a wire or bungee cord to prevent stressing the brake line.
* Rotor: Remove the rotor.
* Ball Joint: Separate the ball joint from the steering knuckle using a ball joint separator.
* Tie Rod End: Separate the tie rod end from the steering knuckle using a tie rod end separator. You'll likely need to use a tie rod separating tool to release the cotter pin and then separate the rod and knuckle with a ball joint separator or similar tool.
* ABS Sensor (if applicable): Carefully disconnect the ABS sensor wire harness.
4. Remove the Hub Assembly: This usually involves removing several bolts securing the hub to the knuckle.
5. Press Out Old Bearing: Using a suitable press, carefully press the old wheel bearing out of the hub. This is critical to prevent damage to the hub.
6. Press In New Bearing: Using the press, carefully press the new wheel bearing into the hub. Ensure it's seated correctly and flush.
7. Reassembly: Carefully reverse the disassembly steps, making sure everything is properly aligned. Pay close attention to the correct torque specifications for all bolts and nuts.
8. Wheel Alignment: After reassembly, it's absolutely essential to have a wheel alignment performed by a professional. Failure to do so can lead to premature tire wear and handling problems.
Important Considerations:
* Rust and seized components: Older cars often have rusted or seized bolts and nuts. Use penetrating oil liberally and allow ample time for it to work before attempting to remove anything.
* Damaged parts: Carefully inspect all components during disassembly. If anything is damaged (beyond normal wear), replace it.
* Torque specifications: Adhering to the correct torque specifications is crucial to prevent damage and ensure safe operation.
Again, this is a simplified overview. A detailed repair manual is absolutely essential for this job. Attempting this without the proper knowledge and tools could lead to serious damage to your vehicle or personal injury. If you're unsure about any step, consult a professional mechanic.
