Here's a general overview of the process. Specific steps and torque specifications will vary depending on your truck's exact configuration and whether you have disc or drum brakes. Always consult a repair manual specific to your year and model Silverado for detailed instructions and torque values. A Haynes or Chilton manual is a good investment for this type of work.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Torque wrench: Absolutely crucial for proper tightening of nuts and bolts. Incorrect torque can damage components.
* Socket set and wrenches: Various sizes will be needed.
* Hammer and punch: Possibly for removing components.
* Bearing packing grease: Specific type for wheel bearings.
* Pry bar: May be helpful for separating components.
* Wheel bearing press (highly recommended): Makes removing and installing the bearings much easier and safer. Trying to do it without one greatly increases the risk of damage.
* Clean rags and shop towels: To keep things clean.
* Penetrating lubricant (PB Blaster, etc.): To help loosen rusted or stuck parts.
General Steps (This is a simplified overview and may not be completely accurate for your specific truck):
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Raise the front of the truck securely using the jack and jack stands.
2. Remove the Wheel: Remove the lug nuts and carefully remove the wheel.
3. Remove the Brake Caliper: Support the caliper with a bungee cord or wire to prevent it from hanging by the brake line. Remove the caliper mounting bolts and carefully set the caliper aside.
4. Remove the Rotor (Disc Brakes) or Drum (Drum Brakes): Depending on your brake system, remove the rotor or drum. This may require removing some additional bolts or components.
5. Remove the Hub Assembly: This usually involves removing the cotter pin, castle nut, and possibly a retaining washer or snap ring. You may need a puller to remove the hub from the spindle. This is where a good repair manual becomes invaluable.
6. Press Out the Old Bearing(s): This is where a wheel bearing press is essential. Attempting to remove the bearings without one is likely to damage them and possibly the hub.
7. Clean and Inspect: Thoroughly clean the hub and spindle. Inspect for any damage.
8. Pack the New Bearing(s): Pack the new bearings with the appropriate bearing grease.
9. Press In the New Bearing(s): Again, a bearing press is crucial for proper installation.
10. Reassemble: Reinstall the hub assembly, rotor or drum, caliper, and wheel, tightening everything to the correct torque specifications found in your repair manual.
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Test Drive: Test drive the vehicle to ensure everything is working correctly. Listen for any unusual noises.
Disclaimer: This is a general guide. Incorrect procedures can lead to serious damage or injury. Consult a repair manual specific to your 2002 Chevy Silverado 1500 2WD for detailed, accurate instructions and torque specifications. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic.
