This weekend, i switched out my ahc suspension. I need to remove the height control accumulator to be able to install my sliders. (It's the can on the left side of the frame rail). For those of you who've removed this, how did you remove the rear top bolt? I can remove three of the four, but this fourth one is giving me a lot of trouble. Is there a specific wrench to use? I can't get this one off. Please help. (i'm finding that most of the difficult things to fix/remove are the ones with the least amount of access.
