How to assemble an ES 4x4?

[Demon Parasite]

Well, I was curious, and popped out an edge from my 4x4. Well, it wouldn't go back in, so I thought, "This can't be that complicated, I'll just take it apart and re-assemble it", but I have no clue where to even start. Could someone show me a tutorial to re-assemble an ES 4x4?

It is a ***** to get in the last piece. Let my just say that.
