deflate the air strut and remove the nut, then wiggle it and see if it comes out. I'm pretty sure i got it out without removing the strut, but maybe not.
If you do have to remove it, it's pretty easy. Deflate it by removing the solenoid (remove the metal clip holding it in, turn it until it stops and pull it out, at which point all the air will come rushing out, probably scaring you, then turn it again and pull it all the way out, or in this case, push it back in and lock it with the clip, being careful not to cut the o ring). The top of the strut is held to the strut tower by 3 or 4 nuts around the edge, you do not have to touch the large center bolt/nut. Undo the nuts and it'll push right down and swing out of your way.
