Found out I was overtorquing lug nuts for 6 years and my impact gun habit was the tip off
One of my regulars came back with a warped rotor on the front left after 2,000 miles, and when I checked the torque wrench it clicked way past spec. I'd been hitting them with the gun until it rattled and calling it good, which is how you stretch studs and warp rotors. Any of you guys actually run a torque stick or do you just trust your arm?
