Place a jack stand immediately behind the jack on the pinch weld.

Slowly lower the car onto the jack stand and remove the jack.

Many hydraulic jacks are lowered by placing the open end of the handle over a knob and turning it counterclockwise. Consult the owner's manual for your jack if you don't know how to lower it.

Never work underneath a car that is only supported by a jack. The jack may slip or fail, resulting in serious injury or death.
