Pre-work lifting checklist for safely raising your vehicle

To lift a vehicle safely, use a firm, level surface, the manufacturer-approved jacking and support points, correctly rated equipment, and a controlled stability test before getting underneath. Chock the wheels, raise the vehicle gradually, place it on jack stands, and lower it onto them; never use a hydraulic jack as the sole support. This checklist covers a one-end lift and the extra controls needed when lifting all four wheels, working with a low-clearance vehicle, or dealing with air suspension.

Are the vehicle, ground, and equipment ready to lift?

Start with a firm, level surface such as sound concrete. Avoid slopes, gravel, soil, wet grass, asphalt softened by heat, drain covers, and any area where a stand could sink, tilt, or slide. Leave enough room to operate the jack, place the stands, open doors, and move around the vehicle without reaching under it unnecessarily.

Before positioning the jack, make sure you have:

• A vehicle parked with the engine off. Select Park for an automatic transmission or first gear/reverse for a manual, then apply the parking brake unless the manual gives a specific reason not to.
• Loose cargo removed and anything that could roll or shift secured. If you need the doors open, confirm the vehicle will not move when they are used.
• Solid wheel chocks that fit the tires. Do not substitute bricks, scrap wood, or unstable objects.
• A jack and stands with a capacity suitable for the vehicle. Do not guess capacity from appearance, and use stands as a matched, compatible set.
• Equipment in good condition. Inspect the jack, stands, locking pins, ratchets, saddles, wheels, and handles. Do not use anything that is bent, cracked, leaking, corroded, missing parts, or difficult to lock.
• Safety glasses and sturdy footwear. Close-fitting work clothing and gloves can help with handling equipment, but keep gloves and loose clothing away from rotating parts when the engine is running.
• A clear work area. Keep children, pets, tools, and anything else that could interfere with the jack or stands away from the vehicle.

Read the owner’s or repair manual before lifting. It may specify different points for a trolley jack and support stands, prohibit lifting at certain locations, or require a particular suspension or air-suspension setting. If the approved points are not clear, do not start by guessing.

How to raise the vehicle and place the stands in the right order

Use this sequence for lifting one end of the vehicle. Match each step to the manual and to the markings on the body or chassis; the exact lift points vary by vehicle.

1. Identify the approved jacking point and the approved support points for the end you plan to raise. Confirm that the metal around each point is sound and free from severe corrosion, cracks, or deformation.
2. Place the wheel chocks tightly against the wheels that will remain on the ground. Chock both sides of at least one grounded axle as directed by the manual; using chocks on both sides of the grounded wheels gives additional resistance to rolling.
3. Position the jack squarely under the approved jacking point. Keep the jack handle and wheels aligned so the jack can move slightly as it rises. Do not lift on suspension arms, steering parts, the exhaust, fuel tank, floor pan, plastic panels, differential housing, or another component unless the manufacturer specifically identifies it as a lift point.
4. Raise the jack slowly until it contacts the lift point. Stop and check that the saddle is centered, stable, and not pressing on a fragile flange or edge.
5. Continue lifting in small increments. Watch the jack, vehicle, and chocks together. Stop if the jack rolls unexpectedly, the vehicle shifts sideways, a lift point bends, or a tire contacts an obstacle.
6. Set the first jack stand at its approved support point and adjust it to a height that will support the vehicle without forcing it sideways. Keep the stand base fully flat on the firm surface.
7. Place the second stand at the matching support point on the other side. Make sure both stands are at compatible heights and that their locking mechanisms are fully engaged.
8. Lower the jack slowly until the vehicle’s weight rests on both stands. Keep the jack in position while lowering, but do not treat it as the support once the stands are carrying the load.
9. Remove or reposition the jack only after checking the stands and completing the stability test. If the job requires extra protection, the manual may allow the jack to remain lightly positioned without carrying the vehicle’s weight; it must not replace the stands.

A stand must contact the approved support area squarely, not an edge, thin panel, brake line, suspension link, or corroded section. If the vehicle needs more height than the stands can safely provide, stop and use equipment designed for that height rather than placing blocks or improvised spacers under a stand.

What must you check before getting underneath?

Treat the first lowering as a setup check, not as permission to crawl underneath. Walk around the vehicle and inspect every contact point before doing any work.

• Confirm each stand is upright, fully seated, and resting flat on the ground.
• Check that every pin, pawl, or locking mechanism is engaged according to the stand’s design. A height-adjustment mechanism must not be resting between positions.
• Confirm the stand saddle is centered on the approved support point and is not slipping toward an edge.
• Look for crushed metal, fresh cracks, severe rust, fluid leaks, or any deformation around the support points.
• Verify that the jack is no longer carrying the vehicle. The vehicle should remain supported by the stands; the jack may be clear or positioned only as secondary protection if the manual and equipment allow it.
• Check that the chocks remain tight against the grounded wheels and that the raised wheels are clear of anything that could catch them.

Then perform a controlled stability test from outside the vehicle. Push firmly against a solid part of the body near the supported end, using enough force to reveal movement but not a violent shove. Watch the stands and their contact points. A small amount of suspension settling can be normal, but the vehicle must not rock, walk, slide, or shift on the saddles.

If anything moves, stop. Do not reach underneath to adjust a stand while the vehicle is supported. Raise the vehicle only enough to remove the load from the stands, correct the setup from a safe position, and repeat the inspection and test. Do not begin work until the vehicle stays stable and the stands, lift points, height, and chocks all look correct.

When should you stop instead of lifting?

Do not lift the vehicle if the ground is sloped, soft, cracked, slippery, or too narrow for the jack and stands to sit squarely. Move to a sound concrete surface or use a properly rated professional lifting facility rather than trying to compensate with boards, blocks, or extra chocks.

Stop if the jack or stands are damaged, mismatched, corroded, missing a locking part, or not rated for the vehicle. Never stack stands, place one stand on another, use loose wood as a height extension, or support a vehicle with a bottle jack, scissor jack, or trolley jack alone.

Stop when you cannot identify the manufacturer-approved lift or support points. A visually strong part is not necessarily designed to carry the vehicle. Suspension, exhaust components, floor panels, plastic trim, and thin pinch-weld sections can bend or fail when used incorrectly.

Do not proceed if the support metal has severe rust, cracking, prior collision damage, or deformation. The stand may be correctly placed and still be unable to carry the load safely. Likewise, stop if the required working height exceeds the safe adjustment range of the stands or if the jack cannot reach the lift point while remaining stable.

Lower the vehicle and reassess if it shifts during lifting or during the push test. If you cannot correct the problem with a firm surface, proper equipment, and clear lift points, use a suitable workshop or a qualified technician. A vehicle that cannot be made stable before you get underneath is not ready for underbody work.

Which extra checks apply to four-wheel lifting or unusual vehicles?

Lifting one end is generally simpler because the other wheels remain on the ground and can be chocked. If you lift both ends, the order matters: secure the wheels that remain on the ground at each stage, follow the vehicle-specific sequence, and make sure the first pair of stands remains stable before raising the other end. Once all four wheels are off the ground, wheel chocks alone cannot prevent every form of movement, so use correctly placed stands at all approved support points and perform the full stability test before getting underneath.

Air suspension can change the vehicle’s height or alter how loads are carried. Follow the manual’s instructions for disabling, locking, or setting the system before lifting. Do not assume that switching off a compressor is enough; some systems can adjust height or release pressure while the vehicle is supported.

For low-clearance vehicles, use a jack that can reach the approved point without riding over bodywork or forcing the vehicle sideways. Ramps or a low-profile jack may be suitable only if they are rated for the vehicle and used on an appropriate surface. Never drive onto ramps that are not restrained or whose angle causes the vehicle to scrape or roll back.

Some vehicles have unusual frames, battery packs, side skirts, active suspension, or manufacturer-specific lifting adapters. The owner’s manual may identify different points from the repair manual, so check the instructions for the exact lifting operation. If the required points, sequence, or equipment are unclear, stop before placing a load on the vehicle.

Conclusion

Once the vehicle passes the stability test, keep the jack stands and chocks in place while you work. Keep the removed wheels nearby only if the manufacturer’s procedure permits them as secondary protection; they are not a substitute for stands. Recheck the setup after any major movement, such as removing a heavy component or applying force with a breaker bar. When finished, raise the vehicle just enough to unload the stands, remove them from a safe position, and lower it slowly onto the ground.

Frequently Asked Questions

Can I leave the jack under the vehicle while I work?

A jack should not be the sole support. After the vehicle is lowered onto correctly rated stands, the jack may remain nearby or lightly positioned as secondary protection only when its design and the vehicle procedure allow it. It must not carry the vehicle instead of the stands or obstruct a stable setup.

Can I use the vehicle’s spare wheel as a safety support?

A removed wheel may provide limited secondary protection in some repair procedures, but it is not a replacement for correctly rated jack stands. It must not be used to support the vehicle at a lift point or as a stand substitute.

How many jack stands do I need?

For one-end work, use the number and positions specified by the vehicle procedure, normally a matched pair supporting the raised end. For four-wheel work, support all four approved points with correctly rated stands and follow the manufacturer’s lifting sequence.
