The bolt slides through a metal sleeve. Check the following excerpts for some useful tips.
This is from a post in another thread:
The solution is surprisingly simple, and im almost offended that your thread got this big and noone could reliably answer your question.
that bolt runs through a split metal sleeve. its holdin on to that friggin bolt. sharpen a screwdriver, or punch, and split it open just a hair, bolt will slide out.
took me two days to figure it out.
impact guns at this stage will only ruin your bushings
I had a problem getting that shock to lca bolt out, i beat on that with a hammer, used a puller, to no avail. So what I did was put an open end wrench between the lca and ear on the shock, over the rubber bushing, then one wack with the hammer and it was out. That works because the rubber bushing it rides in soaks up the impact of the hammer when you beat on it, but if you put the wrench in there, it keeps the force of the impact on the bolt instead of letting the rubber soak it up.
