Here's a breakdown:
1. Identify Jacking Points:
* Frame Rails: The strongest and safest points are the frame rails, the large, sturdy metal beams that run along the sides of the truck. Look for reinforced areas along the frame, usually near the pinch welds (where the body panels meet the frame). Avoid jacking directly on the body or suspension components.
* Jacking Rails (if equipped): Some Silverados have dedicated jacking rails – reinforced sections of the frame specifically designed for jacking. Check your owner's manual for their location.
2. Prepare the Vehicle:
* Parking Brake: Engage the parking brake firmly.
* Level Ground: Ensure the truck is on a level, stable surface.
* Chocks (optional but recommended): Place wheel chocks behind the wheels that are *opposite* the side you're jacking up. This helps prevent the truck from rolling.
* Jack Stands: Have your jack stands ready and positioned *before* you lift the truck.
3. Jacking Procedure:
* Position the Jack: Carefully place the jack on the frame rail or jacking rail at a point that's reinforced and relatively flat. Avoid any welds or sharp edges.
* Slowly Lift: Raise the jack slowly and steadily. Listen for any unusual noises. If you hear anything concerning, stop immediately and investigate.
* Place Jack Stands: Once the vehicle is a few inches off the ground, carefully position the jack stands under a sturdy point on the frame rail (or another appropriate location as specified in your owner's manual). Ensure they're securely in place and can support the weight of the vehicle.
* Lower the Jack: Slowly lower the jack until the weight of the vehicle is fully supported by the jack stands.
* Complete Your Work: Now you can safely work under the vehicle.
* Raise and Lower: To lower the vehicle, use the jack to carefully raise the vehicle slightly off the jack stands, then slowly lower it to the ground. Remove the jack stands, finally removing the jack.
4. Consult your Owner's Manual:
This is the most important step. Your owner's manual will have diagrams showing the exact recommended jacking points for your specific model year and Silverado trim level. It will also provide critical safety information.
Important Safety Considerations:
* Never work under a vehicle supported only by a jack. Jack stands are crucial for safety.
* Use the correct type of jack: Hydraulic floor jacks are generally preferred for their stability and lifting capacity.
* Wear safety glasses: Protect your eyes from debris.
* If you're unsure about any step, consult a qualified mechanic.
Failure to follow these steps can lead to serious injury or damage to your vehicle. Always prioritize safety.
