I'm trying to put in bilstein hds in the rear, not sure how to remove the line from the accumulator that connects to the rear shock. I thought since there are two different hex heads to grab onto, that I could unscrew the one against the shock while holding the other one still. This didn't work with a fair amount of force, and I would like some verification on what I'm supposed to do before I put all my weight into it. Also, if there's anything else I should know, it'd be great if someone could tell me. All I have is the regular bentley manual.
