This guide outlines the general steps. Always consult a repair manual specific to your year and model Silverado for detailed instructions, torque specifications, and diagrams. Differences in specific components and procedures may exist between model years and configurations.
Tools You Will Likely Need:
* Jack and jack stands: Essential for safely lifting the truck.
* Wheel chocks: To secure the vehicle.
* Lug wrench: To remove the wheels.
* Impact wrench (highly recommended): Makes removing and installing nuts much easier.
* Socket set: Various sizes, including those for axle nuts, caliper bolts, and other fasteners.
* Hammer and punch: For driving out components.
* Pry bar: To help separate parts.
* Bearing packing tool: To properly install the new bearing.
* New wheel bearings (front and rear): Make sure to get the correct part number for your truck.
* New seals: These should always be replaced with new bearings.
* Grease: Use a high-quality bearing grease.
* Torque wrench: Absolutely critical for proper tightening.
* Clean rags and shop towels: For cleaning parts.
* Penetrating oil (PB Blaster, etc.): To help loosen rusted bolts.
General Steps (Front and Rear Differ Slightly):
1. Safety First:
* Park on a level surface, engage the parking brake, and use wheel chocks on the wheels that remain on the ground.
2. Remove the Wheel:
* Loosen the lug nuts before jacking up the vehicle.
* Jack up the truck and securely place it on jack stands.
* Remove the wheel.
3. Remove the Brake Caliper and Rotor (Front and Rear):
* Front: Remove the caliper bolts and carefully hang the caliper out of the way using a wire or bungee cord. Remove the rotor.
* Rear: Procedures vary depending on whether you have disc or drum brakes. Refer to your repair manual. If disc brakes, the process is similar to the front. If drum brakes, you'll need to remove the drum assembly.
4. Remove the Hub Assembly:
* Front: This step involves removing cotter pins, castle nuts, and potentially other components like ABS sensors. The hub assembly usually pulls off after removing these.
* Rear: Again, the exact procedure varies depending on your specific axle configuration (solid axle or independent suspension). Consult your repair manual. It often involves removing axle shaft nuts and potentially the axle shaft itself.
5. Remove the Old Bearing(s):
* The old bearing(s) may be pressed into the hub assembly. You'll need a press or other specialized tools to remove them carefully, avoiding damage.
6. Install the New Bearing(s) and Seal(s):
* This requires a bearing packing tool to ensure the new bearing is seated correctly.
* Install the new seals.
7. Reassembly:
* This is the reverse of disassembly, taking care to install all components correctly and tighten all fasteners to the manufacturer's specified torque. Pay close attention to the order of assembly and the use of lock washers, cotter pins, and other securing mechanisms. Incorrect torque can lead to bearing failure.
8. Reinstall the Wheel and Lower the Vehicle:
* Tighten lug nuts to the correct torque specification.
Important Considerations:
* ABS Sensors: If your truck has anti-lock brakes, be very careful with the ABS sensors. Damage to these can lead to costly repairs.
* Torque Specifications: Use a torque wrench and consult your repair manual for the correct torque values for all fasteners.
* Pressing Bearings: You may need a hydraulic press or access to a machine shop for properly removing and installing the bearings.
This is a simplified overview. The actual process is significantly more complex and requires detailed knowledge of your vehicle's specific components and assembly. Refer to a repair manual for your specific 2000 Chevy Silverado 1500 4x4 before attempting this repair. A mistake can lead to serious damage or injury. If you are not experienced, consider having a professional mechanic perform this repair.
