Microsoft now sells official Xbox controller repair parts - Lemmy.world

So what component fixes the stick drift on my standard design lab controller? I only see 6 pieces available and 2 of them are just cosmetic pieces.
I was wondering the same thing about a bumper that doesn’t always fire. Do I need to replace the pcb or just the bumper or maybe both?
