Tools You'll Likely Need:
* 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 bearing removal/installation tool: This is essential and often comes as a kit. You'll need the right size for your hub. Improvising can damage the hub or bearing.
* Hammer and punch (or drift): May be needed for stubborn parts.
* Socket set and wrenches: Various sizes, including those for the caliper bolts, axle nut, and any other suspension components that need removal.
* Penetrating oil (like PB Blaster): To loosen rusted or seized bolts.
* Torque wrench: Crucial for tightening components to the correct specification; incorrect torque can damage parts or lead to failure.
* New wheel bearing: Make sure you get the correct part number for your vehicle.
* Grease: High-quality wheel bearing grease.
* Clean rags or shop towels: To keep things clean.
* Pry bar (optional): Might be needed to help separate components.
Steps (General Outline – Consult your repair manual for specific details):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the wheels that aren't being worked on. Raise the vehicle securely using the jack and place it on jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Brake Caliper: Remove the caliper mounting bolts and carefully hang the caliper out of the way using a wire or bungee cord to avoid stretching the brake line.
4. Remove the Rotor: Depending on the brake setup, you may need to remove the rotor. Sometimes this is simply unbolting it, other times you may need special tools.
5. Remove the Axle Nut: This is usually a large nut on the end of the axle. You'll likely need a breaker bar or impact wrench to loosen it.
6. Disconnect the ABS Sensor (If Applicable): Carefully disconnect the ABS sensor wire from the hub.
7. Separate the Hub and Bearing Assembly: This is where the wheel bearing removal/installation tool is critical. The tool will press the old bearing out and the new one in. This is often the most challenging part of the job and requires the correct tool.
8. Clean and Inspect: Clean the hub thoroughly and inspect it for any damage.
9. Pack the New Bearing with Grease: Properly grease the new bearing according to the manufacturer's instructions.
10. Install the New Bearing: Use the installation tool to press the new bearing into place.
11. Reassembly: Carefully reverse the disassembly process, ensuring everything is torqued to the correct specifications (consult your repair manual!). Pay close attention to the axle nut tightening sequence and torque.
12. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
13. Test Drive: After reassembly, test drive the vehicle to ensure everything is working correctly. Listen carefully for any unusual noises.
Important Considerations:
* Repair Manual: A repair manual specific to your 1996 Chevrolet Cavalier is essential. It will provide detailed instructions, torque specifications, and diagrams.
* Pressed-in Bearings: Wheel bearings in this era are often pressed into the hub assembly. Improper removal or installation can easily damage the hub.
* ABS Sensor: Be cautious when disconnecting and reconnecting the ABS sensor; damage to the wire can cause problems with your anti-lock brakes.
* Torque Specifications: Using the correct torque is critical for safety and component longevity.
This is a complex repair. If you're not comfortable with automotive repair, it's strongly recommended to take your car to a qualified mechanic. A poorly performed wheel bearing replacement can lead to serious safety hazards.
