Find a socket that is bit enough to go over the bolt piece but still contacts the sleeve in the bushing. Then raise the spring pack off the ground so its level with the socket and suppoert it with some wood blocks etc. and beat the bolt with a hammer and drift. If you soak it with lemon juice for a day or so it should break free. You could always us the 2wd pack under the 4wd main leaf if it will not release.
