I can't seem to get my rear bolt holding my rear LCA off. I've got two jackstands holding the subframe up and a jack on the rear differential holding it up ever so gently. I've also go another jack under the LCA with a little pressure on it. I still CANNOT get that one damn 18m bolt out though. I've even tried taking off the rotor and tried hammering on it but it's stuck. It will move, but only if it hit it harder than hell. How does this come out? and more importantly, if it comes out this hard, will I be able to get it back in???
