Introduction
If the control sticks on your Xbox Duke Controller aren't registering input or are registering input when you aren't touching them, use this guide to replace them.
Before using this guide, check to see if there is any dirt or debris clogging the space between the controller and the control stick. Spraying a small amount of contact cleaner into that space and rolling the control stick around can potentially fix the issue. Otherwise, the problem may lie with the potentiometer inside the controller.
A small amount of contact cleaner directly in the potentiometer may work, otherwise they will need to be replaced. Follow this guide up to Step 2 to open up the Duke controller and separate the two halves.
