I used an air impact wrench to get mine free, and that sucker puts out up to 450 ft/lbs of torque. If you don't have an air impact, try a breaker bar. If you don't have a breaker bar, a piece of pipe over the end of your ratchet handle will give you some leverage and the mechanical advantage you need-- the longer the better!
