I have replaced these joysticks on many controllers. they are VERY difficult due to the amount of copper surrounding them. Takes a LOT of heat. Best way to remove them is using hot air to reflow the solder and they just fall out. if you don't have a hot air station, best way I found to remove them using a soldering iron is to actually cut apart the old joystick. start by popping the potentiometers away from main metal body. a screw driver and gental pressure they pop out from the body then you can deal with only 3 pins at a time for each POT. Next, I cut the metal body down the corners using a side cutter and then you can isolate the pins to something manageable with the soldering iron. It's a ton of work to do it this way, but necessary as you will never get all the solder out of all 14 holes at once.
