I just got back from the neighborhood shop. I asked them to take off the set of wheels on my E500 with the snow tires and put on the wheels with the summer tires. The same place put the snow tire wheels on in December, I watched them do it with a torque connector on the air gun, limiting the pressure to 70 pounds. Well, they couldn't get any of the wheels off. They worked on the two back wheels, snapping off a total of four bolts and bending one. The other five they couldn't budge. They borrowed a 3/4 inch gun from a place down the street and all that did was shatter two different sockets.

They said they've seen this before with Benzes and with VW's because they have cast aluminum lug bolts which cause the steel hub threads to corrode. Any suggestions on how to get the remaining bolts out?
