I’m not working in the industry, I guess you could call me a “hobbyist” at best and I never witnessed any failed installs. What is always absent from all these YouTube videos are pictures of cars with mishaps due to improper lifting.
Even the best post foundations won’t save any car that is lifted improperly, out of balance or improper lifting points.
I personally witnessed 2 lazy mechanics, one at a muffler shop - he didn’t even bend over, just kicked the swivel arm under the car and repeated that for the other 3 arms. The mechanic sure jumped quickly when one arm slipped off the pinch weld, now that arm dented the rocker panel and the other arm wasn’t holding up anything. It was the next time about a year later during a state inspection, a kid operating the lift removed 2 rear wheels when the lift was about 2 ft off the ground. Now the kid was raising the car higher and jerking the control stick, the car started to rock and then tipped forwards from being improperly balanced on the lift. The car tipped all the way with the car’s nose hitting the floor. All because the kid wanted to swing the doors free from hitting the posts.
