I just replaced my rear brake hoses on my 86 300sdl and I knew that the rear wheels had not been off in over a year. My tires were rotated by a local shop one year ago and they use an air wrench normally, except when I come in and then they use a torque wrench. This last time though, I could not get the wheel bolts off. It was a pure struggle with a breaker bar, but I finally got them and found that the bolts had rusted to the inside of the rotor. I cleaned them up with a wire brush and used some anti-seize on the and hopefully this will not happen again.
