Putting a car on jack stands is a crucial step for many automotive maintenance tasks, providing a stable and safe support system. The core process involves correctly positioning the stand under the vehicle's designated support point and securely lowering the car onto it.
Overview
Using jack stands safely and correctly is essential before working underneath any vehicle. They provide the stability that a hydraulic jack alone cannot.
Step-by-Step Guide
To safely support a corner (or multiple corners) of your car using a jack stand, follow these steps:
- Identify the Jacking Point: Consult your vehicle's owner's manual to locate the specific jacking points on the frame or body designed to support the vehicle's weight. Using the wrong spot can cause damage.
- Lift the Vehicle: Use a suitable jack to lift the corner of the car you intend to support. Lift it slightly higher than the desired height for the jack stand.
- Position the Jack Stand: Place the jack stand under the jacking point you identified in step 1. Ensure the stand's saddle is centered and making good contact with the jacking point.
- Adjust Height and Lock: Adjust the stand's height to match the desired working height. Use the pin or screw (or pawl in some cases) to lock it in place according to manufacturer's instructions. This mechanism secures the stand at the chosen height.
- Lower the Vehicle: Once the jack stand is locked in place, slowly lower the car to rest on the stand. Do this carefully, ensuring the vehicle's weight settles securely onto the stand's saddle.
- Verify Stability: Give the vehicle a gentle push to ensure it is stable and securely resting on the jack stand.
Important Considerations & Safety Tips
Working under a vehicle is inherently risky if proper precautions are not taken. Always prioritize safety.
- Use on a Flat, Stable Surface: Never place a car on jack stands on uneven or soft ground. A level concrete or asphalt surface is ideal.
- Use Wheel Chocks: Before lifting, place wheel chocks on the wheels that remain on the ground to prevent the vehicle from rolling.
- Support Multiple Points: If you need to support the entire front or rear, use two jack stands placed at the designated points on that axle. If supporting all four corners, use four stands.
- Never Work Under a Car Supported Only by a Jack: Jacks are designed for lifting, not for holding a vehicle's weight long-term while someone is underneath.
- Double-Check: Always double-check the position of the stand, the locking mechanism, and the vehicle's stability before getting underneath.
By following these steps and safety guidelines, you can securely position your car on jack stands for necessary maintenance or repairs.
