Lifting a car on a lift is one of the basic but critical operations in the process of maintenance and repair. Errors at this stage can lead to serious damage to the body, deformation of the sills, or, even worse, the vehicle falling, which poses a direct threat to the life of the mechanic. Therefore, knowledge of the correct algorithms of action is necessary not only for service station professionals, but also for every car owner planning an independent repair.
Modern car lifts are complex engineering structures that require precise positioning. Before starting work, the master must clearly understand where the standard support points of a particular vehicle are located, since there are no universal places for all brands. Ignoring the technical features of the design often becomes the cause of expensive body repairs.
In this guide, we'll walk you through every step of the process, from equipment preparation to final stability testing. You will learn how to avoid common mistakes when working with two-post and four-post lifts, as well as what nuances need to be taken into account when servicing vehicles with different body types and drives.
Preparing the workplace and equipment
The first step is a visual inspection of the lift itself and the surrounding area. The floor in the work area must be absolutely level, dry and free of traces of oil or antifreeze, which can make the surface slippery. Any foreign objects, tools or cans must be removed from the movement area of the lift legs and arms.
It is necessary to check the technical condition of the lifting mechanism. Inspect cables or chains for tears, abrasions and corrosion. If the lift has a hydraulic system, make sure there are no fluid leaks and check the oil level in the reservoir. The locking mechanisms should operate smoothly, without jamming or extraneous squeaking.
Pay special attention to the rubber pads on the lift's feet. They should not be cracked, too hard or show signs of deep wear. Damaged cushions may slip off their support points or damage the anti-corrosion coating on the underbody of the vehicle. If defects are detected, operation of the equipment should be suspended until consumables are replaced.
⚠️ Attention: It is strictly forbidden to use the lift if malfunctions are detected in the operation of the electric drive, hydraulics or mechanical clamps. Trying to lift a car using faulty equipment can lead to an emergency fall.
Studying the diagram of vehicle lifting points
Each car has strictly defined places for lifting, which engineers calculate taking into account the distribution of mass and the strength of the side members. These points are usually indicated by special cutouts in the plastic sill protection or markings on the body itself. An attempt to place the lift arm in an arbitrary place is almost guaranteed to lead to metal deformation.
To find the right support points, it is recommended to use technical documentation or specialized catalogs, which are often available in electronic form at modern service stations. In some cases, information about the location of the lifting points is printed on the inside of the gas filler flap or on the end of the driver's door. Ignoring this data is unacceptable.
Particular care should be taken when working on vehicles with low clearance or fiberglass body kits. In such cases, it may be necessary to use special adapters or extended arms to reach the load-bearing elements of the body, bypassing the decorative elements. The wrong choice of a fulcrum on sports models often ends in breaking through the floor or destroying the threshold.
Where can I look for information if the stickers have worn off?
If the factory markings on the body are unreadable or missing, use the official service manuals for the specific model and year of manufacture. There are also specialized databases (for example, Kwik-Lift or John Bean), where you can find the exact location of the lifting points using the VIN code. Do not rely on visual assessment by eye, as the design of the bottom can change even within the same model range.
The front points are often located closer to the engine and can be reinforced, while the rear points rest on the rear subframe or reinforced areas of the luggage compartment floor.
Positioning the vehicle and installing the paws
When driving the car into the lift target, it is necessary to strictly observe the alignment. The machine should be positioned exactly in the middle between the stands so that the load is distributed evenly on both sides. If the vehicle is tilted to one side, it will place excess stress on one of the lift columns and may cause misalignment during lifting.
The process of placing the paws under the body requires care. The paws should be spread as wide as possible to provide a stable platform, but they should hit the standard support points. Make sure that the rubber pads fit tightly to the metal of the body over the entire contact area. Gaps or touching only with the edge of the pillow are not allowed.
When working with cars that have a central tunnel or protruding exhaust system elements, it is necessary to carefully check the trajectory of the paws. They must not touch the muffler, fuel lines or brake hoses during the lifting process. Visual inspection from below before starting the operation is mandatory.
☑️ Check before lifting
If your car has wide sills or side skirts, use special extended adapters that allow you to bring the paw under the load-bearing element, bypassing the decorative trim. This will prevent the paint from chipping and the plastic from cracking.
Lifting process and initial inspection
Once all the paws are installed, you can begin lifting. Move the control lever smoothly, without jerking. When the wheels lift off the floor, you must stop at a height of 10-15 centimeters and conduct a thorough visual check. This is a critical point that cannot be ignored.
Walk around the car and make sure that all four paws rest firmly on the body and do not slide off. Check whether the sills or support points have deformed under load. If you notice a misalignment or hear a suspicious metal noise, immediately lower the vehicle and reinstall the feet.
Make sure the car is stable and does not wobble when pushed slightly. If the lift is a two-post lift, check that the cables or chains are evenly tensioned. Any asymmetry at this stage can lead to the car “steering” to the side at maximum height.
| Vehicle type | Features of lifting points | Risks due to errors |
|---|---|---|
| Sedan/Hatchback | Points on reinforced sections of thresholds | Threshold deformation, floor damage |
| SUV (frame) | Support on the frame, not the body | Damage to hanging elements, misalignment |
| Electric car | Special areas for battery protection | Damage to the traction battery (fire) |
| Sports car | Low ground clearance, adapters needed | Destruction of body kits, breakdown of the bottom |
When lifting electric vehicles, use only certified dielectric lifts and strictly follow the manufacturer's instructions regarding lifting points to avoid damaging the high-voltage battery pack located in the floor.
Only after making sure that the fixation is secure at a low height can you continue lifting to the desired level. Raising the car suddenly without an intermediate check is a serious mistake.
Fixation and work at height
When the vehicle is raised to the required height, the mechanical safety locks must be activated. On two post lifts these are usually ratchets or pins that fit into holes in the posts. Never rely on hydraulics or electrics alone—mechanical locking is the last line of defense.
Before crawling under the vehicle, perform a stability test. Grab a wheel or suspension element and try to rock the car. She should stand "dead". If play or movement of the paws is felt, work cannot be continued. It is also recommended to install safety stands (traces) under critical components if long-term work or dismantling of heavy units is planned.
Security When working at height, it means prohibiting the vehicle from swinging. Do not rest your entire weight on the body or use it as a support for tools. Any impact work (for example, knocking out rusty bolts) is best done when the car is standing on the ground or on additional safety supports, since vibration can disrupt the fixation on the legs.
⚠️ Attention: It is prohibited to stand under the vehicle if it is raised only by pressure in the hydraulic system without engaging the mechanical clamps. Hydraulics can leak at any time.
Mechanical locking of the struts is a prerequisite for starting any work under the car. The hydraulic cylinder is not a safety net.
When working on wheels, make sure that the vehicle is secured against rotation. If wheel removal is required, unscrew the bolts sequentially, checking the stability of the machine after removing each wheel, especially if a diagonal unscrewing pattern is used.
Lowering the vehicle and completing the work
Completing work requires the same care as starting it. Before lowering, ensure that all tools are removed, new parts are installed correctly, and that there are no people in the work area under the vehicle. Remove the mechanical clamps and smoothly lower the car, monitoring the process visually.
When the wheels touch the floor, do not rush to immediately pull your paws out. Allow the vehicle to rest fully on its wheels to remove stress from the support points. Only after this can you move your paws to the side. Sudden pulling of the paws from under a loaded vehicle can damage the rubber cushions or scratch the body.
After freeing the vehicle from the lift, it is recommended to once again inspect the support points for damage. This will help you notice possible problems in time and avoid claims from the client in the future. The lift should be returned to its original position with the arms lowered to the minimum height for the next vehicle.
Regular maintenance of the lift itself, including lubricating moving parts and checking electrical contacts, will extend its life and ensure the safety of personnel. Don't forget to keep a maintenance log for your equipment.
What to do if the car starts to roll when climbing?
Stop lifting immediately and lower the vehicle. Check that it is level between the posts and that the legs are extended equally on both sides. Often the reason lies in the fact that one of the paws hit the bottom terrain ahead of time or slipped. Repeat the positioning procedure.
Is it possible to lift a car by a subframe?
Lifting by the subframe is only possible in exceptional cases and only if it is expressly permitted by the vehicle manufacturer's instructions for specific work (for example, engine replacement). In normal modes, you need to rely only on reinforced points of the body or frame specially designed for this purpose.
How often do rubber pads on paws need to be changed?
The regulations depend on the intensity of work of the service station, but they need to be visually inspected daily. Replacement is required when cracks appear, loss of elasticity, or if the rubber has become “oaky.” Worn rubber slides on the metal and does not provide proper grip.
Is it dangerous to lift a car with a full tank of fuel?
A full tank in itself is not a prohibition, since the fuel tank is a standard structural element. However, the overall weight of the vehicle increases, so it is important not to exceed the maximum lift capacity. Weight distribution with a full tank also changes, which is worth considering when balancing.
