So im planning on upgrading my shocks next weekend and I always hear that the rear shock bolts snap while trying to get them out. I plan on hitting them with some PB blaster for the week. What is the best method to getting them out without issues. Should I go by hand or with an impact? I am trying to make it as painless as possible. The shocks were probably done a few years ago by previous owner and there isnt too much rust but I know that can be deceiving.
