Tools Needed:
* Jack and jack stands: Absolutely crucial for safety. Never work under a car supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Wheel alignment tool (optional but recommended): Though not strictly necessary for the bearing replacement, it's highly advised to get an alignment afterwards.
* Torque wrench: Essential for tightening bolts to the manufacturer's specifications. Incorrect torque can damage components.
* Hammer: For separating parts (may need a rubber mallet to avoid damage).
* Pry bar: To help separate parts.
* Socket set (metric): You'll need various sizes, likely including deep sockets. Consult your repair manual for specifics.
* Wrench set (metric): Again, consult your repair manual.
* Penetrating oil (like PB Blaster): To loosen rusted or seized bolts. Apply liberally and let it sit.
* Bearing press (highly recommended): This tool is crucial for safely removing and installing the wheel bearing. Improvising can damage the bearing or hub. A quality bearing press is a worthwhile investment if you do this type of repair frequently.
* New wheel bearing: Get the correct bearing for your specific vehicle. The part number is essential.
* New ABS sensor (possibly): If your ABS sensor is integrated with the bearing assembly, it needs replacement too.
* Grease: Appropriate wheel bearing grease.
* Clean rags: To keep things clean.
* Repair manual (highly recommended): A Haynes or Chilton manual specific to your 1997 Chevy Cavalier will provide detailed instructions, torque specifications, and diagrams.
Procedure (General Outline - Consult Your Repair Manual for Precise Steps):
1. Safety First: Secure the vehicle with the parking brake, wheel chocks, and jack stands.
2. Remove the Wheel: Loosen the lug nuts, jack up the car, secure it on jack stands, and remove the wheel.
3. Remove the Caliper: Unbolt the caliper and carefully hang it out of the way using a bungee cord or wire to avoid straining the brake line.
4. Remove the Rotor (disc brake): Remove the rotor. This may require some persuasion depending on how much rust is present.
5. Disconnect the ABS Sensor (if applicable): Carefully disconnect the ABS sensor if it's part of the bearing assembly.
6. Remove the Axle Nut: This is often very tight and may require significant effort and a breaker bar.
7. Separate the Hub and Bearing Assembly: This is where the bearing press comes in. You'll need to carefully press the bearing out of the hub. This step can be very difficult without the proper tools and technique.
8. Clean and Inspect: Clean the hub thoroughly before installing the new bearing.
9. Install the New Bearing: Use the bearing press to carefully press the new bearing into the hub. Ensure it's seated correctly.
10. Reassembly: Reassemble everything in reverse order, ensuring proper torque on all bolts. Refer to your repair manual for specific torque specifications. This is critical to prevent damage.
11. Wheel Alignment: After reassembly, get a wheel alignment done. This is crucial for safe and proper vehicle handling.
Important Notes:
* This is a simplified overview. Each step may involve multiple sub-steps and require specialized knowledge.
* Always consult your repair manual for specific instructions and torque values for your vehicle.
* Improper installation can lead to serious damage or injury.
* If you are not comfortable performing this repair, take your car to a qualified mechanic.
This repair is best attempted by someone with experience working on cars. The use of a bearing press is strongly recommended to avoid damaging the new bearing. Always prioritize safety.
