Serious question, why do so many guys still torque lug nuts with an impact and call it done?
Had a car come in Tuesday with a warped rotor and two studs stretched so bad the wheel was basically sitting on hope. Owner said the tire place in Bakersfield zipped them on with a gun 6 months ago and never checked anything, and you could feel the shake at 40 mph. A torque wrench costs less than one comeback job, and it takes maybe 20 extra seconds per wheel. Are shops actually teaching this or are new guys just picking it up from whoever trained them?

Right, because nothing says "I care about your safety" like zipping a lug nut on with 600 ft-lbs and calling it a day (the gun does all the thinking, clearly). I watched a guy at a shop near me run all five lugs down with the impact, no socket back-off, no nothing, and then act shocked when the customer came back with a wobble. The best part is these same guys will swear up and down their gun "stops at the right torque" (sure it does, buddy). Twenty extra seconds with a torque wrench versus a comeback and a pissed off customer, seems like a pretty easy math problem to me.
