Originaly it's glued and put together with some spotweld aluminium taps. As there's a big force on the frame in the aluminium shell on the location of hinges the glue break lose and the spotwelds break. My solution is to drill holes through the outer shell beside both hinges. use 2.4 drill and m3 tap and screw a 3mm screw right through the shell into the frame.
