Davefr - You and I seem to be the only people in the world that have a problem with that. When I try to point out the problem of torquing a preloaded wheel, people just give a blank stare...
I didn't think one was supposed to use a torque wrench for removing bolts - only for putting them on. Maybe I'm wrong??quote:

I had a bad experience with my local Costco last year. The guy who torqued down my wheels did not follow procedure and must have used an impact wrench. I didn't notice anything wrong until my brakes started pulsing (the rotors on this car are susceptible to warping if the wheels are overtorqued). Even at the max. 200 lb-ft torque setting, I couldn't get my torque wrench to take off the lugs. I had to get out the breaker bar.
Suffice to say that I'll be keeping my eye out and my torque wrench handy the next time I have my tires balanced and rotated at that Costco.
I think that is about the worst thing you could do to try and take off your lugnuts. The sudden up and down jumping can put all kinds of stress on the threads and studs.quote:

the real question is,
how many times has the tq wrench been dropped
or when was the last time they were ever checked for accuracy?
