are you trying to just pull them off? just hit the bolts with a hammer, theyll come out unless the inner sleeves from the bushings rusted to the bolts..then youll need a air chisel or some kind of press to get them out.
or are you trying to remove the bolts with the coils in there? if so, they wont come out because the coil is putting tremendous pressure against them. I never take the front suspension apart like that, altho some people swear by it. Its the biggest pain in the ass IMO. I always pop the ball joint apart then pull the spring out from there..
