Remove the two Philip's Head screws from the bottom underside of the seat-back back panel. Remove the panel sliding it downwards and you have access to the large nut securing the armrest pivot frame to the seat back! Nice write up and good job! But those pictures would be nice if you did it again, if it rains of course. And if you could do it for the FAQ's just think how many would benifit from your experience! You can add the armrest R&R now!
