How to Jack Up a Car with a Floor Jack: Step-by-Step Instructions
What looks like a simple lift can become dangerous in seconds if the jack is placed on the wrong point or the car is allowed to roll A floor jack is useful for tire changes brake work oil changes and other repairs but it is.
I wrote this guide to explain how to jack up a car with a floor jack without guessing. You will learn what equipment you need, how to identify safe lifting and support points, how to place jack stands, and how to lower the vehicle under control.
The instructions apply to most cars, crossovers, and light trucks, but the vehicle owner’s manual always takes priority. Lift-point locations, ground-clearance requirements, and support procedures can vary significantly by model.
What a Floor Jack Does—and Does Not Do
A floor jack is a wheeled hydraulic tool designed to raise part of a vehicle. It uses a saddle, or lifting pad, to contact a designated point on the vehicle and lift the tires off the ground.
A floor jack is not a permanent support. Hydraulic pressure can drop, seals can fail, and the jack can move if the floor is uneven. For that reason, I use a floor jack to raise a vehicle, then place properly rated jack stands underneath before working near or beneath it.
Never rely on the floor jack alone while changing parts, inspecting the underside, or reaching into a wheel well. The jack should remain available as a backup lifting tool, not as the only thing holding the car up.
Equipment and Safety Checks
Gather the equipment before positioning the car. Interrupting the job to search for a missing tool can lead to rushed decisions.
- A floor jack with a capacity greater than the vehicle’s weight
- Two or four jack stands with appropriate weight ratings
- Wheel chocks or solid blocks that cannot easily slide
- The vehicle owner’s manual
- A lug wrench or socket set, if removing a wheel
- Work gloves and safety glasses
- A flashlight for locating lift and support points
Choose the right floor jack
Check the jack’s rated capacity on its label or manual. The capacity must be high enough for the vehicle, but capacity alone does not guarantee safe use. The jack also needs enough lifting height to raise the intended tire or suspension component and enough clearance to fit under the vehicle.
A low-profile jack may be necessary for a sports car or a vehicle with very little ground clearance. A taller jack may be more suitable for a truck or SUV. I do not place blocks under a jack to gain extra height; that can make the jack unstable and cause it to slip.
Inspect the equipment
Look for bent parts, cracked welds, damaged wheels, leaking hydraulic fluid, a loose saddle, or a handle that does not operate normally. Do not use a jack stand with a bent frame, missing locking mechanism, or damaged height-adjustment components.
Follow the equipment manufacturer’s instructions for inspection and operation. A tool that worked correctly last year may not be safe if it has been stored in moisture or overloaded.
Prepare the Car Before Lifting
Preparation prevents many vehicle-lifting accidents. Park on a firm, level surface such as a concrete garage floor or a flat paved driveway. Avoid grass, gravel, loose dirt, steep slopes, wet pavement, and surfaces that can sink under the jack or stands.
Put the transmission in Park for an automatic vehicle. For a manual transmission, select first gear or reverse. Apply the parking brake, then turn off the engine and remove the key or key fob from the vehicle.
Clear people, pets, and loose objects from the work area. Open the hood if you need to check the jack or monitor the vehicle, but keep the hood and doors closed unless the repair requires otherwise. Opening a door can shift the vehicle’s weight unexpectedly.
Chock the wheels that stay on the ground
Place wheel chocks tightly against the tires that will remain on the ground. If the front of the vehicle will be raised, chock the rear wheels. If the rear will be raised, chock the front wheels.
For extra control, place a chock on both sides of a tire when the vehicle’s design and available space permit. Do not substitute loose bricks, rounded stones, or thin pieces of wood for purpose-made chocks.
Loosen lug nuts before lifting
If a wheel will be removed, loosen each lug nut slightly while the tire is still on the ground. Turn each nut only enough to break its initial resistance; do not remove it yet.
This step matters because the tire s contact with the ground prevents the wheel from spinning Trying to loosen tight lug nuts after lifting can move the vehicle.
Find the Correct Lift Points
The safest lifting point is the location identified by the vehicle manufacturer. Check the owner’s manual first, then use the vehicle’s service information if more detail is needed.
Common lifting points include reinforced pinch-weld areas along the rocker panels, front or rear subframes, designated crossmembers, and a central differential housing on some rear-wheel-drive vehicles. These locations are not interchangeable on every car.
A reinforced point is designed to carry lifting force. A thin floor pan, plastic panel, exhaust component, oil pan, fuel tank, suspension arm, or body seam may bend or break under the jack saddle even if it appears convenient.
Front lift points
Many vehicles have a central front lift point on a reinforced crossmember or subframe. Some require each front side to be lifted separately at a marked pinch weld. The manual may show a symbol, notch, arrow, or diagram indicating the location.
Before lifting, shine a light behind the bumper and under the engine compartment. Confirm that the saddle will contact metal intended for lifting rather than a plastic cover or a fragile component.
Rear lift points
Rear lifting points may be located at the rear subframe, a reinforced crossmember, or the differential housing on certain solid-axle vehicles. A differential housing is not automatically a safe point on every vehicle, especially on some independent rear suspension designs.
Never assume that a visually strong component is approved for lifting. A part may support driving loads but still be unsuitable for the concentrated force applied by a jack.
Pinch welds and adapters
Many unibody vehicles use reinforced pinch welds near the bottom edge of the rocker panel. These points can be narrow and easy to damage if the saddle is not centered.
A manufacturer-approved pinch-weld adapter can help keep the saddle aligned and protect the seam. The adapter must fit the vehicle and remain stable on the jack. Do not improvise with a loose block, a cut pipe, or stacked materials.
How to Jack Up a Car with a Floor Jack
The basic process is to position the jack, raise the vehicle gradually, support it with stands, and verify stability before beginning work. I keep my hands and feet away from the underside while the vehicle is moving.
1. Position the floor jack
Roll the jack under the selected lifting point. Keep the jack handle oriented so you can pump it without standing in the vehicle’s path if it shifts. Center the saddle directly beneath the approved point.
Make sure the jack’s wheels can roll as the arm rises. A floor jack normally moves slightly during lifting, so the wheels must not be blocked by a wall, curb, tool, or floor crack.
Before applying pressure, check that the saddle is level and that nothing under the vehicle will be crushed. If the saddle is not contacting the correct point, lower the jack and reposition it rather than trying to correct the alignment while loaded.
2. Raise the vehicle slowly
Pump the handle gradually. Watch the saddle and the contact point during the first few inches of movement. Stop immediately if the saddle slides, the vehicle leans sharply, a tire chock moves, or a component begins to deform.
Lift only as high as necessary to place the jack stands at their approved support points. For a tire change, that may mean only enough clearance to remove the tire. For work under the vehicle, use the minimum height that provides the required access.
3. Place the jack stands
Position the stands under the manufacturer-designated support points. These may be separate from the lifting points. A lifting point is designed for the jack; a support point is designed to carry the vehicle while it remains raised.
Set both stands to the same or nearly the same height when supporting one end of the vehicle Keep each stand upright with its base fully flat on.
If the vehicle is raised at one central point, place a stand on each side at the specified support locations. Do not position stands so close to the edge that their feet could slide off the solid floor.
4. Lower the car onto the stands
Move the jack’s release valve slowly and lower the vehicle in a controlled manner. Keep watching both stands as the vehicle’s weight transfers to them. The stands should remain vertical, and their saddles should stay centered.
Once the vehicle rests on the stands, leave the floor jack lightly touching a suitable lifting point if doing so does not interfere with the repair. Do not use it as the primary support, and do not place it where a small shift could push the car sideways.
5. Perform a stability check
Before getting underneath, inspect the setup from several angles. Confirm that the stands are fully engaged, the bases are flat, the chocks are still tight, and the vehicle is not resting on an unstable component.
Apply a cautious push at a solid body area, such as a door pillar, using controlled force. Do not shove the car aggressively. If the vehicle rocks, the stands move, or the jack saddle shifts, stop, move clear, and lower the vehicle to correct the setup.
Never crawl beneath a vehicle that has not passed this stability check. If the job requires all four wheels off the floor, use four properly placed stands and follow the vehicle-specific lifting sequence. Raising one end can change the load on the other end and affect wheel-chock effectiveness.
Supporting One End or All Four Wheels
For a front-wheel tire change, raising only the front end is usually sufficient. For rear brake work, raise only the rear if the repair and vehicle instructions allow it. Supporting one end reduces the number of variables and generally makes the setup easier to inspect.
To raise all four wheels, use a sequence that keeps the vehicle stable. The correct order depends on the vehicle’s lift points and weight distribution. I follow the service manual rather than assuming that the front or rear should always be lifted first.
After the first end is supported, the chocks and stands may need to be reconsidered as the vehicle’s weight shifts. A chock that worked before lifting may no longer be tight against the tire. Recheck every contact point each time the vehicle is raised.
Never place a jack stand under a moving suspension arm unless the manufacturer specifically identifies that location for support. A suspension arm can move when the vehicle’s weight changes, causing the stand to lose contact.
Working Safely Once the Car Is Raised
Keep the repair plan within the vehicle’s stable support arrangement. Do not pull aggressively on a seized part, use excessive force with a long breaker bar, or apply sudden side loads that could shift the vehicle.
Use additional support for components that can change the vehicle’s balance. For example, removing a heavy drivetrain component, fuel tank, or suspension assembly may transfer weight in a way the original support arrangement was not designed to handle.
Keep tools, removed wheels, and parts organized. A removed wheel can sometimes be placed flat beneath a strong portion of the vehicle as a secondary precaution, but it is not a substitute for correctly positioned jack stands. Do not count on it to catch a falling vehicle.
Do not work beneath a vehicle supported by a scissor jack, bumper jack, bottle jack alone, or a floor jack alone. A roadside emergency may require a temporary tire change using the manufacturer-supplied jack, but that situation does not make the setup suitable for extended work beneath the car.
How to Lower a Car from Jack Stands
Remove tools, parts, and people from beneath the vehicle before lowering it. Confirm that the wheels can contact the floor without hitting a stand, jack, chock, or other object.
Position the floor jack at the approved lifting point and raise the vehicle just enough to take the weight off the stands. Remove the stands from both sides and place them out of the vehicle’s path.
Open the release valve slowly. Lower the vehicle in a controlled motion while watching for interference. Once the tires are firmly on the ground, remove the jack and reinstall or reposition the wheel chocks as needed.
If a wheel was removed, tighten the lug nuts in a star or crisscross pattern. Lower the vehicle completely before applying final torque with a properly calibrated torque wrench. Use the torque specification in the owner’s manual or service information, not a guess based on how tight the nuts feel.
After lowering, check that the parking brake is set, the transmission is in Park or a selected gear, and all equipment is clear. Before driving, verify that the vehicle behaves normally and that no tools remain under it.
Common Mistakes to Avoid
Using an uneven or soft surface
A jack can sink, tilt, or roll unpredictably on asphalt softened by heat, gravel, soil, or grass. If no firm surface is available, postpone the repair or use a professional service facility.
Lifting at a convenient but unsafe location
Convenience is not a safety specification. Oil pans, transmission cases, suspension arms, exhaust pipes, and body panels may be damaged by the concentrated pressure of a jack saddle.
Failing to chock the wheels
The parking brake usually operates on only two wheels and cannot prevent every type of movement. Chock the wheels that remain on the ground before lifting.
Putting stands under the wrong structure
A jack stand under thin sheet metal can punch through the floor or rocker panel. Locate the reinforced support points in the manual and inspect the contact area before lowering the vehicle.
Raising the car too high
Extra height increases the amount of potential movement and makes stability more difficult. Raise the vehicle only as far as the repair requires.
Using mismatched or damaged stands
Use stands in pairs when supporting one end and keep their capacities appropriate for the vehicle. Do not mix unstable homemade supports with rated equipment or use a stand with a damaged locking mechanism.
When a Professional Should Handle the Lift
I would stop and seek professional help if the vehicle has severe rust around the lift points, a bent frame, collision damage, a missing owner’s manual, or unclear support locations. Rust can weaken the exact structure that appears to be a normal pinch weld or subframe.
Professional service is also the safer choice when the vehicle cannot be parked on a firm, level surface or when the required repair involves removing a major component that changes the vehicle’s balance.
If the floor jack does not fit beneath the vehicle, do not force it under the car or drive onto random boards to create clearance. Use a jack designed for the vehicle or have the vehicle transported to a location with suitable equipment.
FAQ
Where should I place a floor jack under a car?
Place the floor jack only at a manufacturer-designated lifting point. Common locations include reinforced pinch welds, front or rear subframes, crossmembers, and certain differential housings. Check the owner’s manual because the correct point differs by vehicle.
Can I work under a car supported only by a floor jack?
No. A floor jack is for lifting, not for dependable long-term support. Place properly rated jack stands at the vehicle’s designated support points before working beneath the car.
How high should I jack up a car?
Raise it only high enough to perform the intended task. For a wheel removal, lift until the tire clears the ground. For underbody work, use the minimum height that provides safe access while keeping the stands fully stable.
Do I loosen lug nuts before or after lifting?
Loosen them slightly before lifting, while the tire remains on the ground. Ground contact keeps the wheel from spinning. Remove the lug nuts only after the vehicle is safely supported.
Can I use wood between the floor jack and the car?
Do not use loose wood, stacked blocks, or improvised materials to create lift height or compensate for a wrong lifting point. Use a properly sized jack and an approved adapter when the vehicle requires one.
Can I lift a car on gravel or grass?
It is unsafe because the jack or stands can sink, tilt, or slide. Use a firm, level surface such as sound concrete or stable pavement, or have the job performed at a professional facility.
How do I know if a jack stand is positioned correctly?
The stand should sit upright on a flat, firm base, with its saddle centered beneath the manufacturer-designated support point. After lowering the vehicle, confirm that the stand remains vertical and fully engaged before approaching the underside.
