2 post lifts

I’m always very safe while under a car and agree I need one with auto locks.
I don’t think I would have grabbed onto the car like that. The one guy did the right thing and GTFO
But he went back under. If the arms are locked and under the car it cannot come down. Always use tall stands under the rear diff. When you start taking things off the front . It will tilt back on an asometric lift.
