Which part of the vehicle should the jack be placed under?

The jack is located on the left side of the car trunk. There are two common types of car jacks: one is the rack jack, and the other is the screw jack. How to use a rack jack: Open the jack to form a diamond shape, with the top being the support part and the bottom being the base. Place the base downward and the support part under the car's chassis. Insert the jack into the gap between the chassis and the ground, use the wheel hub bolt wrench as a crank, and simply turn it. How to use a screw jack: Place the base directly on the ground with the support part under the vehicle's chassis, insert the wheel hub bolt wrench into a small hole to act as a crank, and then turn it. When using the jack, you can place the spare tire under the chassis to prevent the vehicle from suddenly falling, providing an additional support.

I've had multiple experiences using a jack. Typically, vehicle chassis have specially designed lifting points, usually located near metal protrusions on the inner or outer side of the wheels, such as reinforced structures beneath the rocker panels or in the axle area. These spots are the strongest and safest, capable of bearing the vehicle's full weight without deformation or slippage. If you jack up the car at weak points like plastic covers or un-reinforced panels, it can easily lead to vehicle collapse, jack failure, or even personal injury. I recommend beginners first check the illustrations in the owner's manual, which clearly mark the exact locations. The positions vary by vehicle model: sedans often have metal protrusions front and rear, while SUVs usually have them near the axles. Always operate on level ground, align the jack properly, and avoid working on slopes. I make it a habit to inspect the lifting points with my phone's flashlight for cleanliness before proceeding. Safety first—never overlook these small details during tire changes.

That day when my car had a flat tire and was parked on the roadside, I had to find the correct lifting point when using the jack from the trunk. Generally, the lifting points of vehicles are located on the chassis, such as the metal protrusions near the four wheels or the reinforced structures under the side sills. A lesson I learned before was lifting at the wrong spot, which scraped off some paint from the body and nearly caused damage. Choosing the right point ensures the jack can steadily support the vehicle, preventing slipping or damage. If you're unsure about the location, you can crouch down and feel the chassis to find the sturdiest-looking spots. The owner's manual is a great helper, as it provides detailed markings. In repair shops, it's common to see incorrect lifting causing rust or deformation on the chassis. I recommend everyone to pay attention to these points and get familiar with their car's structure. For safety, always confirm point-to-point contact before use and avoid operating on muddy ground. Among car repair tips, this one is particularly crucial and should not be overlooked.

If it's your first time using a jack, locate the designated points on the vehicle's chassis to lift. These points are usually near each tire, marked by metal protrusions or indicators, which are sturdy and weight-bearing. Avoid lifting on plastic or thin sheet areas, as they can easily get damaged. Before use, ensure the ground is level and the jack is stable. The manual contains diagrams for quick reference. This method ensures safer tire changes when lifting. Keep it simple and straightforward for easy operation.
