I had to use a 1/2"drive breaker-bar,with a 3' pipe extension. After hopping on each lug for about 5-minutes,they finally gave-in! Make sure to pre-soak the lugs with "Kroil",or a good brand of penetrant first. I soaked them and let it "soak",for a week. They musta been torqued at 350 ft. lbs!! Hope this helps.
