Is it an original long bolt or the replacment shorter type? The long bolts reach to the outer edge of the wheel. If its a long bolt be very carefull. They are easy to break, and once broken they're pretty much impossible to get out. Come to think of it, if the short bolt breaks you've probably got just as much of a mess because of the flanged seat on the bolt. But the short bolts don't break as easy. If the bolt breaks than you will most likely have to destroy the wheel to get it off. There isn't any pratical way to drill out the flange on the bolt that holds the wheel on. You'll have to drill into part of the wheel.

I would think you will have better luck with an impact gun than a long breaker bar. But don't hold the gun on the bolt for more than a few seconds. Give it short blips at full power. Sometimes giving it a blip in the clockwise direction first helps break the rust.

Search this forum. This is a common problem.
