In the realm of automotive maintenance and roadside emergencies, the car jack stands as an indispensable tool, enabling vehicle owners to safely lift their cars off the ground, making it possible to access the undercarriage, change tires, or perform necessary repairs.
The car jack’s pivotal role in vehicle maintenance and repair stems from its ability to provide a stable and secure platform, allowing mechanics and DIY enthusiasts to work beneath the car with confidence. It facilitates various tasks, including tire changes, brake inspections, oil changes, and exhaust system repairs.
Despite its critical function, many drivers may not fully understand the different types of car jacks available and their respective applications. This article aims to shed light on the various types of car jacks, their specific uses, and the safety precautions that must be taken when using them.
What is a Car Jack Used For?
A car jack is a device used to lift vehicles off the ground.
- Lifting vehicles
- Changing tires
- Performing repairs
It provides a stable platform for working beneath the vehicle.
Lifting vehicles
Lifting vehicles is a primary function of a car jack. This process involves raising the vehicle off the ground to provide access to the undercarriage, wheels, and other components for inspection, maintenance, or repair work.
Car jacks are designed to safely and securely lift vehicles of various weights and sizes. They employ different mechanisms to achieve this, such as hydraulics, pneumatics, or mechanical leverage. Hydraulic car jacks utilize a hydraulic pump to generate pressure, which is then transferred to a piston that lifts the vehicle. Pneumatic car jacks operate on compressed air, while mechanical car jacks rely on gears and levers to lift the vehicle.
When lifting a vehicle with a car jack, it is crucial to ensure stability and safety. The car jack should be placed on a level and solid surface, and the vehicle’s parking brake should be engaged. Additionally, chocks or wheel stoppers should be placed behind the wheels that are not being lifted to prevent the vehicle from rolling.
Once the vehicle is lifted to the desired height, it is essential to use jack stands to support the vehicle’s weight. Jack stands are sturdy metal supports that are placed under the vehicle’s frame to ensure it remains securely elevated while work is being carried out.
Lifting vehicles with a car jack is a common and necessary task for various automotive maintenance and repair activities. By following proper safety procedures and using the appropriate equipment, you can safely and effectively lift your vehicle to perform the necessary work.
Changing tires
Changing tires is a common task that many drivers will encounter at some point. A car jack is an essential tool for safely and easily lifting the vehicle to access and remove the flat tire.
To change a tire using a car jack, follow these steps:
- Park the vehicle in a safe location. If possible, park on a level and solid surface away from traffic.
- Engage the parking brake and put the vehicle in gear. This will prevent the vehicle from rolling while you are working.
- Place chocks or wheel stoppers behind the wheels that are not being lifted. This will further prevent the vehicle from rolling.
- Locate the jack points on your vehicle. These are usually indicated by small notches or markings on the frame or body of the vehicle. Make sure to use the correct jack points for your vehicle.
- Position the car jack under the jack point. Ensure that the jack is stable and will not slip.
- Pump the jack handle to lift the vehicle. Continue pumping until the flat tire is off the ground.
- Loosen the lug nuts on the flat tire. Do not remove the lug nuts completely at this point.
- Lift the vehicle further until the flat tire is completely off the ground.
- Remove the lug nuts and take off the flat tire.
- Place the new tire on the wheel studs.
- Hand-tighten the lug nuts.
- Lower the vehicle until the tire is just touching the ground.
- Tighten the lug nuts with a lug wrench until they are snug.
- Lower the vehicle completely and remove the car jack.
Changing a tire can be a messy and challenging task, but it is a necessary skill for all drivers. By following these steps and using the proper safety precautions, you can safely change a tire using a car jack.

A car jack is also commonly used to perform repairs on the underside of a vehicle. This could include tasks such as:
- Oil changes
- Brake repairs
- Exhaust system repairs
- Suspension repairs
- Drivetrain repairs
To perform repairs using a car jack, follow these steps:
- Park the vehicle in a safe location. If possible, park on a level and solid surface away from traffic.
