i've heard about that happening, i work for the company, they fire the person who did it and they fire the service manager and the guy that checked the work. back when i worked on machinery, i had to replace a bunch of stuff on a skidsteer (basically a bobcat thing) because they didnt torque the wheels every 25 hrs being run. cost em like 5k to fix.loose lug nuts? my dads wheel fell off after a mechanic at pepboys forgot the torque them to spec
