A lot of people don't realize that a torqued fastener takes more torque to remove than it took to tighten. I've had to remove lug bolts that I've tightened myself to 85 lb ft with a 4' pipe. The impact wrench would not make them budge.
This happened recently on my 01 Jeep Grand Cherokee. I was doing the front brakes and none of the lug nuts on the right, front wheel would budge. And I was the last one with the wheels off - I rotated the tires front to back. Obviously something was going on because none of the lug nuts would budge but it wasn't the way they were tightened.

When I had to put a 3 foot length of pipe on the wrench to get enough torque on it to remove them, I couldn't believe, even with an air gun, some idiot could get them on that tight! While cheaning the inside of the rim, once off, it gave me a chance to see just what a great piece of engineer that wheel is. It looks pretty plain on the outside, but a lot of thougth went into that wheel. I think they spent more money engineering the clip ring for the benz star in the centre, than most companies spend in R & D for the whole front corner suspension. :-) Ed 300E On 19/08/07, Robert Bigham <[EMAIL PROTECTED]> wrote: > > 250 ft lb is way too much torque on spherical collar screws holding on > steel > or alloy road wheels. > > My Daimler Benz Passenger Car Technical Data book says tighten them > to 110 NM, equal roughly to 81 ft lb if I didn't botch the conversion. > > No wonder they are hard to get off when torqued to 250 ft lb.
