Its time to change your breaks or perform other maintenance on your vehicle that requires you to remove your wheel and tire. This will require jacking up or lifting you vehicle. This process is inherently dangerous if not performed correctly. Failure to follow proper protocol can lead to severe injury or permanent structural damage to your vehicle. This guide outlines the essential steps and critical considerations for raising your Car or SUV using a floor jack and jack stands, prioritizing safety and efficiency.
Prepare for Success:
- Vehicle Owner's Manual: This book, typically located in the glove compartment, holds vital information regarding your vehicle's gross weight and designated jack points, both crucial for a safe lift. Additionally, the VIN sticker within the driver's door jamb offers details on gross vehicle weight (GVW), including front and rear axle loads.
- Hydraulic Floor Jack: While most vehicles come equipped with a scissor jack for emergencies, it's not recommended for DIY auto mechanics. Opt for a hydraulic floor jack sized to exceed your vehicle's weight capacity. These typically range from 1.5 to 4 tons (3,000 - 8,000 lbs). Remember, 1 ton equals 2,000 lbs.
- Vehicle Jack Stands: Ensure the jack stands' weight capacity surpasses your vehicle's weight. They typically range from 2 to 6 tons (4,000 - 12,000 lbs).
- Wheel Chocks: These secure the wheels not being raised, preventing accidental rolling and dislodgement from the jack stands. Place them both in front and behind the tires for added stability.
- Optional: Plywood can protect your driveway from scratches and indentations on asphalt or blacktop. A rubber pad on the floor jack or jack stands minimizes underbody damage.
Safe Lifting Procedure:
- Safety Observer: Due to the inherent risks, consider having a second person observe and provide assistance or call for help if needed.
- Clear and Secure Work Area: Choose a level, firm surface away from traffic and potential hazards. Avoid areas near moving vehicles, slopes, loose gravel, or unstable ground like dirt or grass.
- Engage Parking Brake and Transmission: Activate the parking brake and ensure the vehicle is in park (automatic) or first gear (manual) to prevent rolling.
- Chock the Tires: Securely position wheel chocks against the wheels not being raised, both front and back, to prevent forward or backward movement.
- Locate Designated Jack Points: Refer to your owner's manual to identify the reinforced points on the frame, subframe or pinch welds/rails designed for safe jack placement. Never use bumpers, suspension components, engine or transmission.
- Position the Jack and Raise Slowly: Center the jack base securely under the designated point and raise the vehicle slowly and steadily, monitoring its stability throughout the process.
- Place Jack Stands and Lower Jack: Once the vehicle reaches the desired height (slightly above your intended jack stand placement), slide sturdy jack stands beneath the designated support points near the jacked areas. Consult your manual for specific locations. Slowly lower the jack once the jack stands fully support the vehicle.
- Double-check Stability: Before working under the vehicle, gently push it front-to-back and side-to-side to ensure stability. Verify the jack stands are secure and positioned correctly.
DIY Brake Pro Tips:
- Never work under a vehicle supported only by a jack.
- Use a rubber pad on the jack or jack stands to protect the underbody of a vehicle and avoid unintended scratches or damage.
- Consider plywood on the driveway for asphalt surfaces to prevent scratches or indentations.
- Seek professional help if unsure about any step or feel uncomfortable.
By following these instructions and prioritizing safety, you can raise your car or SUV efficiently and with minimal risk. Remember, caution and preparation are paramount when dealing with lifting thousands of pounds off the ground!
