However, if you're determined to do it yourself, here's a general outline. Remember that this is a *general* guide and specific steps may vary depending on your exact truck model (e.g., Silverado, Colorado, etc.). Always consult a repair manual specific to your year, make, and model. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safely lifting the truck.
* Wheel chocks: To prevent the truck from rolling.
* Lug wrench: To remove the wheels.
* Torque wrench: Crucial for tightening bolts to the correct specifications.
* Socket set and wrenches: Various sizes will be needed.
* Hammer and punch: For removing and installing components.
* Bearing race and seal installer/remover: These specialized tools make the job much easier and prevent damage.
* Penetrating oil: To loosen rusted or seized bolts.
* Wheel bearing packing grease: The correct type for your bearings.
* Clean rags or shop towels: To keep everything clean.
* Safety glasses and gloves: Protect yourself from injury.
General Steps (Consult your repair manual for specific details):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Wear safety glasses and gloves.
2. Remove the Wheel and Tire: Loosen the lug nuts before jacking up the truck. Jack up the truck securely and place it on jack stands. Remove the wheel and tire.
3. Remove the Brake Caliper and Rotor: Carefully remove the brake caliper assembly (you may need to support it with a bungee cord or wire) and then remove the brake rotor.
4. Remove the Hub Assembly: This is often the most challenging part. You'll likely need to remove various bolts and possibly the cotter pin holding the axle nut in place. The hub assembly may be pressed onto the spindle, requiring a press or other specialized tools for removal.
5. Remove the Old Wheel Bearing: Once the hub assembly is off, you'll need to carefully remove the old wheel bearing races and the bearing itself. This often requires bearing race and seal removal tools.
6. Clean and Inspect: Thoroughly clean the hub assembly and spindle. Inspect the spindle for any damage.
7. Install the New Wheel Bearing: Pack the new wheel bearings with grease (follow the instructions on the grease packaging and your repair manual). Install the new races and bearing using the appropriate tools. Make sure everything is seated correctly.
8. Reassemble: Reassemble everything in reverse order of disassembly. Pay close attention to the torque specifications for all bolts and nuts. Use a torque wrench to ensure proper tightening.
9. Torque Specs: The torque specifications for your specific vehicle are *critical*. Incorrect torque can lead to bearing failure or damage to other components. Consult your repair manual.
10. Test: After reassembly, test drive your truck carefully. Listen for any unusual noises from the wheel.
Important Considerations:
* 4x4 Specifics: Four-wheel-drive systems often add complexity. You may need to disconnect CV axles or other components.
* ABS Sensors: Be careful not to damage the ABS sensor if your truck is equipped with anti-lock brakes.
* Hub Seals: These often need replacing along with the bearings.
Again, this is a simplified overview. You absolutely must consult a repair manual specific to your 2005 Chevy 4x4 pickup before attempting this repair. Improper installation can lead to serious damage or injury. If you're not comfortable with the task, take your truck to a qualified mechanic. It's safer and often cheaper in the long run to have a professional handle this type of repair.
