Actually, the analog stick is very hard to break. What most often happens is that the internal plastic piece gets misaligned with the metal sliders which control the X and Y axis, leading to a false perception that it is broken. I have repaired a few of these sticks myself by realigning the pieces, but over time it will get permanently bad and you need to get a new one to replace it. It is a design flaw in the PS stick in my opinion.
