Here's a general overview of the process. This is *not* a comprehensive guide and specific steps may vary slightly depending on your Silverado's trim level and options. Always consult a repair manual specific to your vehicle's year and model for detailed instructions and torque specifications.
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.
* Impact wrench (highly recommended): Makes removing and installing nuts and bolts much easier.
* Socket set and wrenches: Various sizes will be needed.
* Ball joint separator: To separate the ball joint from the control arm.
* Tie rod end separator: To separate the tie rod end from the steering knuckle.
* Wheel bearing press/puller set: Essential for pressing the old bearing out and the new one in. This is usually a specialized tool. Trying to improvise could damage the hub.
* Torque wrench: Crucial for tightening bolts to the correct specification. Incorrect torque can lead to premature failure or damage.
* Penetrating oil (PB Blaster, etc.): Helps loosen rusted or seized bolts.
* Grease: Pack the new bearing with fresh grease.
* New wheel bearing: Make sure you get the correct part number for your vehicle.
General Steps:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Raise the vehicle safely using a jack and secure it with jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Disconnect Components:
* Brake Caliper: Carefully remove the brake caliper and support it to prevent damage to the brake line.
* Rotor: Remove the brake rotor (may require some persuasion if rusted).
* Tie Rod End: Use a tie rod end separator to disconnect the tie rod end from the steering knuckle. Important: Note the position of the tie rod end before disconnecting to ensure proper reassembly.
* Ball Joint: Use a ball joint separator to separate the ball joint from the control arm. Again, note the position.
* ABS Sensor (if applicable): Carefully disconnect the ABS sensor if present.
4. Remove the Hub Assembly: This is often held on by large bolts. You'll likely need the impact wrench here.
5. Remove the Old Bearing: This requires the wheel bearing press/puller set. Carefully press the old bearing out.
6. Install the New Bearing: Using the press, carefully press the new bearing into the hub assembly. Ensure it's seated properly. Pack the new bearing with grease.
7. Reassembly: Reverse the disassembly process, carefully reconnecting all components. Pay close attention to the proper torque specifications for all bolts, especially the axle nut.
8. Lower the Vehicle: Carefully lower the vehicle and reinstall the wheel.
9. Torque Specifications: Double-check the torque specifications for all components in your repair manual. This is critical for safety and longevity.
Important Considerations:
* ABS Sensor: If your vehicle has an ABS system, be extremely careful with the ABS sensor. Damage to it can lead to ABS malfunction.
* Torque Specifications: Using the correct torque specifications is absolutely crucial. Improper torque can lead to failure of components and safety hazards.
* Repair Manual: Obtain a repair manual specific to your 2005 Chevy Silverado. This will provide detailed instructions, diagrams, and torque specifications.
* Professional Help: If you're not comfortable with any part of this process, take it to a qualified mechanic. This is a safety-critical repair.
This is a simplified overview. This job is best done with a detailed repair manual and the proper tools. Incorrect installation can lead to serious safety risks. Again, consider seeking professional help if you're unsure.
