Hey, I am just starting to do a lift on my 87 wrangler and the Bolt on the bushing for the leaf spring will not come out! The bolt spins freely but it won't slide out...I take that back it spins but just barley. I think it's stuck on the rubber bushing. I have tried heating it with a torch but it didn't help much. Also tried a sledge hammer but that didnt work. I need some ideas to get it loose.
