Around here, none of the tire/brake shops/dealerships even know what a
torque wrench is when it comes to wheels, except surprisingly, Wal Mart
of all places. They've been stuck with the bill for so many bent wheels
and rotors that now, at least in this area, they at least use torque
sticks on all wheel mounts ( and they will instantly fire any employee
who sticks a wheel on without using them). Although their torque chart
isn't completely accurate, at least they are close and all the bolts get
pulled down evenly.

There's is nothing more aggravating than to discover some tire changer has
put 200#'s of torque on the lugnuts! Especially if you discover it while
trying to change a flat tire next to a busy highway, in the dark, in the
rain or snow. Those guys should be tracked down and tortured!
The typical torque for a wheel with 5 lugnuts/bolts is approx. 90'#'s - in
addition to the difficulty removing the nuts/bolts when changing a tire,
there's a likelyhood the rotors were warped when they were over-torqued.

Subject: Re: [MBZ] How to remove tight lug bolts?
A friend of mine had a 560SEL with stuck lug bolts. A large impact
wrench eventually broke off 5 bolts. He had to drill them out. They
broke where the thinner shaft behind the hex meets the spherical
section that fits the wheel. If the last guy (a brake shop) to touch
those bolts hadn't been 800 miles away, I'm sure a cheater bar would
have been applied to his head.

If you have the air tools, an impact is less likely to twist anything
you don't want twisted than a cheater bar, but if the bar is the only
thing that is going to do it, get a good long one and instead of steady
pressure, jump on it in short bursts to crack it loose....then find the
last guy to put the bolts on so tight and take the cheater bar to him
