The screw jack relies on its self-locking thread structure to support the vehicle, with high safety and stability. However, its lifting ability also needs to be based on correct operation. If the jack is not pushed in the correct position, it will not only be futile, but also damage the vehicle.

The front swing arm screw is a component on the car chassis, but it is clearly not the correct lifting position for the car.

Because there are dedicated support points at the bottom of the vehicle to support the jack, such as the front swing arm screw, which does not protrude from the chassis steel plate and cannot withstand high pressure, the screw may crack.

Supporting the jack on the front swing arm screw may cause unnecessary damage to the chassis, deform the vehicle, and affect its driving. In addition, supporting on the lower swing arm of the suspension is also an incorrect operation. If the jack slips and the vehicle falls down, the screws of the front swing arm and the jack will be damaged.

The correct position for using a screw jack to lift the vehicle chassis is usually on both sides of the chassis, near the wheels.
