Summary
  • Jack stands support a vehicle after it’s been lifted by a jack.
  • Place the jack stands underneath the car at the designated jack points and test their stability before working under your car to ensure your safety.
  • Make sure to use a jack stand that can support the weight of your vehicle.
  • Make sure the surface under the jack stand won’t allow the jack stand to sink into it.

Whether you need to repair, replace a part, or simply inspect something under your vehicle, jack stands can make the job a lot safer than just working under the car while it is being supported by a hydraulic jack. Of course, it’s important that you know how to properly set them up.

According to the National Highway Traffic Safety Administration (NHTSA), it’s estimated that over 4,500 people get injured due to jack failures. Most of them involve the vehicle slipping or the jack failing.

As such, it’s important to know the proper steps when using a floor jack and setting up your jack stands to support the vehicle rather than trusting the hydraulic jack.

How to Safely Use Car Jack Stands

To use a jack stand without risk of it failing, you’ll need a jack and wheel chocks or wooden boards.

If you’re unfamiliar, wheel chocks are wedges, often made of plastic, wood, or rubber, that are placed against the wheels to prevent the car from moving forward or backward. This ensures you can safely work on your vehicle without the risk of it rolling.

Once you have everything you need, follow the steps below:

Ask for Assistance (Optional)

An extra pair of hands is always helpful when working on your vehicle. A friend could help you spot things you might have missed and hand you the tools needed while you’re working on your car.

But since most of us have only two hands and might not have a friend to help, we can still get the job done by ourselves. We just need to double check everything and be very careful.

Find a Flat Surface

You need to find a perfectly flat and level surface to jack up your vehicle. The slightest of slopes could result in your car rolling or shifting out of place when the tires are lifted.

Pro Tips are nuggets of information direct from ASE-certified automobile technicians working with CarParts.com, which may include unique, personal insights based on their years of experience working in the automotive industry. These can help you make more informed decisions about your car.

Pro Tip: The surface needs to be smooth enough for the wheels on the jack to roll as the vehicle is being jacked up unless you’re using a bottle jack or some other type that isn’t on casters.

Caution: Keep in mind: jack stands won’t work well on a sloped surface. Don’t use jack stands on asphalt on a hot summer day without putting a piece of plywood larger than the base of the stand underneath the jack stand. A sinking jack stand can cause the vehicle to shift and fall unexpectedly. Don’t ever use a jack stand on sand, dirt, or gravel; always concrete that is flat and level.

Once you find a safe spot, put your vehicle in park if you’re driving an automatic or first gear if you own a manual transmission car to keep it still. If you’re not working on the rear brakes, set the park brake as well.

Place the Wheel Chocks

Put the wheel chocks around the grounded wheels to ensure your car doesn’t move forward or backward. If you’re on level ground, something as simple as a brick or a four-by-four block in front of and behind two of the wheels will do the job.

Place the Floor Jack at the Designated Jack Points

Before lifting your vehicle, check for the jacking points.

Once you locate the jack points, place the jack under the lifting point and raise the vehicle, and then put a stand as near the jack as you can on the pinch weld, axle tube, or frame (see illustrations). Fully lower the hydraulic jack once the car is pressed against the stands.

Ensure Stability

Push the car to verify the stands are stable in their place. The stands must be at the same height to ensure the vehicle is level. Once you’ve confirmed that the setup is stable and level, you should be able to work safely under your car.

Lower the Car

Lower the car. Keep lowering until the nearest wheel makes contact with the ground. Repeat for all OEM lift points.

How to Remove Car Jack Stands

To remove your vehicle from the jack stands, follow the steps below:

Raise Your Vehicle off the Jack Stands

Roll the floor jack underneath the vehicle until it’s lined up with the lift point you used. Raise it until the stand is loose enough to unlock the jack stand lever so the ratchet bar can fall free.

Pull the Jack Stand

Slide the jack out without going underneath the vehicle.

Lower the Jack

Turn the lever on the floor jack counterclockwise to lower the vehicle. Once the tires hit the ground, roll your jack out from under the car. into it.

Lift the Vehicle

Place your jack under the lift points and raise your vehicle on each side if you need to remove other jack stands. Remove both jack stands from the front first before removing the ones in the back if your vehicle is jacked off the ground.

Pro Tip: Make sure there are no screws, small rocks, or rough pavement to prevent the jack wheels from rolling as the car is raised, because that’s part of how using a floor jack works. It rolls as it raises the vehicle.
