How to Lift Car with Scissor Jack: A Practical Step-by-Step Guide
A scissor jack can lift one corner of a car for a tire change when the vehicle is parked on firm, level ground and the jack is placed at the manufacturer-designated lift point. Raise the car only high enough to clear the tire, and never work beneath a vehicle supported only by this jack.
The small detail that changes the entire decision is not how far the jack can extend; it is whether the jack’s saddle matches the car’s lift point and whether the ground can keep its base stable. A compact emergency jack may be suitable for a roadside wheel change, but it is not a substitute for a floor jack and jack stands during repairs.
What should you check before turning the handle when a flat tire leaves the car partly on a slope or soft shoulder? This guide explains the equipment, parking and chocking procedure, lift-point inspection, correct raising and lowering sequence, common mistakes, vehicle-height limitations, and situations where a professional or safer recovery option is necessary. By the end, you can decide whether the scissor jack is appropriate and lift the vehicle with much less risk of a tip, slip, or sudden drop.
What a Scissor Jack Can and Cannot Do
A scissor jack uses a threaded screw to open two hinged arms. As the arms spread, the saddle rises and lifts a small section of the vehicle’s frame or pinch weld. The design is compact and inexpensive, which is why many cars include one with the spare tire.
Its intended job is usually an emergency tire change. It can lift one wheel off the ground, but it is slower and generally less stable than a hydraulic floor jack. It also provides little room for repositioning once the vehicle is raised.
Never use a scissor jack as a long-term support. Do not crawl under a car held only by the jack, shake the vehicle to test its stability, or leave it elevated while shopping for parts. For brake, suspension, exhaust, oil, or underbody work, use a properly rated floor jack and jack stands on suitable ground.
What You Need Before Lifting the Car
Gather the vehicle’s scissor jack, lug wrench, spare tire or repair equipment, and the owner’s manual. A pair of wheel chocks is strongly preferred; if they are not available, use solid blocks that cannot easily roll, but never substitute loose rocks or small objects.
Wear gloves if the wheel or roadside surface is dirty, and use a flashlight in low light. A reflective vest, warning triangles, or roadside safety lights can help make the vehicle visible, but they do not make an unsafe stopping location safe.
Check the jack before loading it. The screw should turn without binding, the arms should not be bent or cracked, and the saddle and base should be intact. Confirm that the jack’s capacity meets the vehicle requirement, rather than assuming every factory jack fits every model.
- Owner’s manual or the vehicle’s printed lifting instructions
- Scissor jack with a stable, undamaged base
- Lug wrench and the correct locking-wheel-nut adapter, if applicable
- Spare tire inflated to the required pressure
- Wheel chocks or solid blocks for the wheel opposite the lift point
- Flashlight and roadside visibility equipment when needed
Park and Secure the Vehicle First
Move to the safest available location before unpacking the jack. A hard, level surface such as sound pavement is best. Avoid soft soil, gravel, mud, steep grades, road crowns, drainage channels, icy surfaces, and places where passing traffic could strike the vehicle.
Turn on the hazard lights and apply the parking brake. Shift an automatic transmission into Park or a manual transmission into first gear or reverse, following the vehicle’s instructions. Turn the engine off, remove the key or secure the start system, and have passengers exit on the side away from traffic when possible.
Place a chock on each side of the wheel diagonally opposite the corner being lifted. For example, if the right-front wheel is being raised, secure the left-rear wheel. Chocking reduces rolling, but it does not correct a steep slope or replace a stable parking location.
Before lifting, remove heavy cargo if practical and keep people clear of the vehicle. A passenger moving inside the car can shift its balance while the jack is carrying the load.
Find the Correct Jacking Point
The correct lift point is specified in the owner’s manual and may also be marked by arrows, notches, reinforced seams, or molded indicators along the rocker panel. Many unibody cars use reinforced sections of the pinch weld, while some vehicles have a dedicated pad behind each front wheel or ahead of each rear wheel.
Do not place the saddle under a random part of the floor pan, plastic side skirt, suspension arm, fuel tank, exhaust component, or thin body panel. These areas can bend, crack, or allow the jack to slide. A location that looks strong is not necessarily designed to carry the vehicle’s lifting load.
Clear away mud and inspect the point with a flashlight. Look for severe rust, crushed metal, missing trim, or an unclear contact area. If the prescribed point is damaged or inaccessible, stop rather than improvising with a block of wood or a nearby suspension component.
How to Lift Car with Scissor Jack Safely
The following sequence is suitable for a basic wheel change, provided the vehicle, surface, and jack are appropriate. Keep your hands and feet away from the underside and from the jack’s moving arms while it operates.
1. Loosen the lug nuts slightly
Before raising the tire, remove the wheel cover if necessary and fit the lug wrench fully onto each lug nut. Turn each nut counterclockwise about one-quarter to one-half turn. Do not remove them yet.
The tire’s contact with the ground holds the wheel steady while you break the initial friction. If the nuts are extremely tight, do not use a long pipe or jump on the wrench while the car is elevated. A damaged nut or a shifting vehicle can create a serious hazard.
2. Position and orient the jack
Set the jack base flat on the ground, with its broadest face fully supported. Place the saddle directly beneath the designated lift point and align it as the manual shows. The screw or operating handle should remain accessible without putting your body under the car.
On a pinch-weld lift point, the saddle may need to engage a slot or reinforced flange. Make sure the weld sits in the saddle’s intended channel rather than on its edge. If the jack leans before carrying weight, lower it and correct the position.
3. Raise the saddle until it contacts the vehicle
Turn the handle slowly, usually clockwise to raise the jack. Stop when the saddle just touches the lift point, then recheck that the base is flat and the contact is centered.
This contact check is essential because a misplaced jack can look stable while unloaded but shift as the car’s weight transfers onto it. Keep the vehicle doors closed and do not make adjustments by reaching beneath the car.
4. Lift only until the tire clears
Continue turning the handle steadily. Watch the jack, the lift point, and the tire rather than looking away for long periods. Raise the vehicle only far enough for the damaged tire to clear the ground by roughly an inch, or by the minimum amount needed to install the inflated spare.
Stop immediately if the base tilts, the saddle walks along the lift point, the jack arms twist, the car shifts, or unusual cracking and popping occurs. Lower the vehicle if necessary and choose a safer location or arrange roadside assistance.
5. Remove the wheel and install the spare
Finish removing the loosened lug nuts and keep them together where they cannot roll into traffic. Pull the wheel straight toward you. If it is stuck to the hub, do not strike it aggressively or place your body beneath the car; lower the vehicle and seek help if the wheel cannot be freed safely.
Place the spare onto the hub and hand-tighten the lug nuts in a crisscross pattern. Hand-start every nut to avoid cross-threading. Keep the spare centered while tightening, but do not apply full force until the tire is back on the ground.
6. Lower the vehicle and tighten the nuts
Turn the handle slowly counterclockwise to lower the car. Keep watching the saddle and base as the load comes off. Once the tire touches the ground and cannot rotate freely, remove the jack and finish tightening the lug nuts in a star or crisscross sequence.
Use the vehicle’s specified torque if a torque wrench is available. A lug wrench can provide a temporary roadside tightening, but avoid overtightening, which can damage studs, rotors, or the wheel. Replace the wheel cover only if it fits securely over the spare.
After driving a short distance, stop in a safe location and recheck that the spare is secure. A temporary spare may have strict speed, distance, and inflation limits printed on its sidewall or listed in the manual. Follow those limits and arrange a permanent tire repair or replacement promptly.
Important Stability and Safety Checks
A scissor jack is most vulnerable while the car is rising and lowering. Keep the load centered, turn the handle smoothly, and do not add weight to the vehicle. Never use a jack on a surface that can compress under the base, even if the surface appears level.
- Do not lift more than one wheel with a single scissor jack.
- Do not place any part of your body under the raised vehicle.
- Do not start the engine, shift gears, or release the parking brake while elevated.
- Do not use the jack to pull, push, or straighten a vehicle.
- Do not stack bricks, boards, or improvised objects under the saddle to gain height.
- Do not continue if the designated lift point has serious rust or collision damage.
Modern cars may have low ground clearance, side skirts, battery components, or unusual lift-point designs. Conversely, a lifted truck or SUV may sit higher than the jack’s maximum height. If the tire cannot clear the ground before the jack reaches its limit, lower it and use equipment designed for that vehicle.
When a Scissor Jack Is the Wrong Choice
Do not attempt the job on a moving shoulder, a steep hill, a soft verge, or a location with poor visibility if the vehicle can be moved safely to a better place. If traffic, weather, darkness, or injury makes the work unsafe, call roadside assistance instead.
A damaged jack, missing lift-point information, seized lug nuts, a bent wheel, or a spare with inadequate inflation are also reasons to stop. A professional can secure the vehicle with suitable equipment rather than relying on a marginal emergency setup.
For garage work, a floor jack and jack stands are the appropriate combination. The floor jack provides controlled lifting, while stands support the vehicle at approved points after it is raised. Even then, the car should remain on firm, level ground and the stands should match the vehicle’s weight and lift-point requirements.
Frequently Asked Questions
Can a scissor jack lift any car?
No, it must match the vehicle’s weight, height, and designated lift point. Check the jack rating and the owner’s manual, and make sure the jack can raise the tire clear without reaching its mechanical limit.
How high should I raise a car with a scissor
Raise it only until the tire is barely clear of the ground. Extra height increases instability and gives the jack more opportunity to lean or slip.
Can I work under a car supported by a scissor
No, never work underneath a vehicle supported only by a scissor jack. Use a properly rated floor jack and jack stands at approved support points for any task requiring access beneath the car.
Where does the scissor jack go on a car?
It goes at the manufacturer-designated lift point nearest the wheel being changed. This is often a reinforced pinch-weld section or marked lifting pad, but the exact position varies by vehicle.
How do I lift car with scissor jack
Avoid lifting it on a slope whenever possible. A scissor jack is intended for firm, level ground; if the car cannot be moved safely, stay clear and contact roadside assistance rather than relying on extra chocks.
Why is my scissor jack leaning while I raise
A leaning jack usually indicates an uneven base, incorrect lift point, poor alignment, or excessive height. Stop turning the handle, lower the vehicle carefully if safe, and reposition it only on firm ground and at the prescribed point.
Should I loosen lug nuts before or after lifting?
Loosen them slightly before lifting and finish removing them after the tire is off the ground. Ground contact prevents the wheel from rotating while you break the nuts loose.
Lift Only for the Tire Change
The safest way to use a scissor jack is to park on firm, level ground, chock the opposite wheel, engage the exact factory lift point, and raise the vehicle only enough to change one tire. The major limitation is stability: this compact jack is emergency equipment, not a support system for under-car repairs.
Inspect the jack and lift point before applying weight, stop at any sign of slipping or damage, and use roadside assistance or a floor jack with jack stands when conditions are unsuitable. After installing the spare, tighten the lug nuts correctly and follow the spare tire’s operating limits.
