How to Properly Use a Jack Stand? | Safety Steps That Matter

Using a jack stand properly means supporting the vehicle on reinforced points, then confirming stability before you go underneath.

Working under a car supported only by a hydraulic jack is a gamble. A jack stand is the piece of equipment that makes the job safe — but only when it’s used correctly. The right sequence is simple: lift, place, lower, test. Properly using a jack stand means distributing the vehicle’s weight on reinforced points, never trusting a jack alone, and verifying everything is solid before you slide underneath.

The Core Safety Sequence For Using Jack Stands

Every proper jack stand setup follows the same steps, whether you’re changing oil or swapping a brake rotor. The order matters as much as the parts involved.

• Park on a flat, hard, level surface. Concrete is ideal. Gravel, soil, soft asphalt, or a slope can let stands sink or tip while you’re under the car.
• Set the parking brake and chock the wheels that stay on the ground. This keeps the vehicle from rolling while you lift one end.
• Consult the owner’s manual for the manufacturer-designated jacking and support points.
• Lift with the floor jack only high enough to slide the stands into position beneath the load-bearing points.
• Set the stand height so the saddle makes firm contact before you transfer weight.
• Lower the vehicle slowly until the full weight rests on the stands.
• Verify the stands are vertical, centered, and locked according to the stand design—pins or locking mechanisms engaged.
• Push the vehicle gently to check for rocking, settling, or shifting before you commit to working underneath.

Leaving the floor jack in place with its saddle just under the vehicle adds a secondary layer of support after the load transfers to the stands. It’s a good backup—never the primary support.

Where Do You Place Jack Stands Under A Car?

The owner’s manual is the authoritative source for your specific vehicle’s support points. General guidance points to reinforced areas designed to carry the vehicle’s weight: frame rails, pinch welds, subframes, or axle housings.

Places to avoid are just as important. Oil pans, transmission pans, plastic panels, exhaust parts, and suspension components are not built to hold the vehicle’s full weight and can crack, bend, or fail without warning. When in doubt, look for the reinforced pinch weld seams along the frame—the same points where factory jacking equipment attaches.

Always use stands in pairs when supporting an axle or end of the vehicle. A single stand creates an unbalanced load, and mixing stands of different capacities or heights in the same setup invites uneven stress. Both stands should be set to the same height before lowering the vehicle.

Common Mistakes That Lead To Failures

The most dangerous errors aren’t complicated—they’re shortcuts that feel fine in the moment.

• Working on soft or uneven ground. Soft asphalt and gravel are the most common culprits because stands sink slowly without any obvious warning.
• Relying on a hydraulic jack alone while working underneath. A jack is a lifting tool, not a support tool. Seals can fail, and vehicles have crushed people this way.
• Using the wrong lift point or setting the stand on a non-reinforced part of the vehicle. The stand must sit on the same load-bearing points the manual designates.
• Skipping the stability test. A quick push or shake tells you whether the vehicle is settled or still shifting.
• Using mismatched stands. Unequal height or capacity across a pair puts one stand under disproportionate load.

If any of these conditions exist, the setup isn’t ready. Fix the problem before you go underneath—not after you hear something shift.

Removing The Stands After The Job

Taking the vehicle down is the reverse of the lifting sequence. Slightly raise the vehicle with the floor jack to take the load off the stands. Remove the stands once the weight is off them, then lower the vehicle slowly back to the ground. Lower it all the way before you remove the wheel chocks or release the parking brake.

For heavier or industrial work, match the stand’s load rating to the vehicle’s weight—never exceed a stand’s stated capacity. The steps above work for any vehicle; only the support points and required load rating change.

If you’re working on a vehicle with a transmission or gearbox that needs extra support, the right stand makes the difference between a clean job and a dangerous one. Our roundup of gearbox jack stands covers tested options rated for transmission work, so you can pick the right tool before you start.
