I had to tear mine off, in order to put a new, straight pair of A-arms and a new straight shock on. It's not really too bad, but be prepared to remove a lot of screws.
Like they said above, you pull pretty much everything. If you get the sled propped up on it's side, it makes the job pretty easy. You will need to pull the bottom skid plate(I'm not sure if we should call the plastic piece a skid plate, but whatever) off in order to remove the bottom A-arm.
Don't waste your time doing anything with the toolkit that AC sent you. Get a real #20 torx. As long as your coherent enough to operate a screwdriver, you shouldn't have to worry about stripping any of the screws. If you do, a phillips head(square) will usually still remove them.
