You run the very real risk of twisting off the stud with your cheater. When the wrench monkey ran that nut up to the wrench's limit, he probably created a multitude of tiny nut to stud welds from the friction. You probably won't be able to break them loose with continuous torque. Only the shock of another impact wrench will do that. If you can't get to a shop, an emergency measure that might work is to heat the nut with a torch until it passes the "spit test". Lick your finger, touch the nut and if it hisses and bounces your finger away from the steam, it's hot enough. Do NOT heat any hotter, as you can easily remove the heat treat from the stud. As a matter of standard practice, I'd replace the stud after heating it.

Don't EVER let the tire monkeys use an air wrench to tighten your lug nuts. Specify "hand torque only". They're used to that request. A particularly large specimen of tire gorilla can still over-tighten the lugs but he'd have to work at it. This goes for any passenger vehicle wheel and not just alloy wheels. Warped brake rotors, broken studs and wallowed out lug holes are other results of air wrench tightening. John |
