Start by removing screws, as bits of plastic become loose, remove them too. If any of these bits of plastic have wires attched, unplug them. Then reassemble in reverse order, there will probably be 6 or so screws left over at the end, scratch your head for a while, then put them in a sandwich bag and leave in glove box until you hear a squeak, put job of finding squeak into the "too-hard basket" and discard screws.
