thank you, but I tried opening mine and the analog assembly looks a little bit different from yours. for one the outer casing is black plastic instead of white, and on the sensor inside it only has 2 black pads while the other ones are just bare copper traces. also there are no small black piece that holds #2 in place.

I tried cleaning them still with mixed result. it does help with the jitter issue (in my case the analog keeps being tilted down on its own randomly) but it doesn't entirely fix the problem for me.

replacing the whole analog part might be the only way but sadly it's hard to find replacement for
