Here is how to swap your Envision’s thumbsticks.

1. Begin by gently pulling the faceplate from the top of the controller and carefully lift it over the thumbsticks.
2. Next, grab the thumbstick you want to remove and pull up firmly.
3. To place on a new thumbstick, align the hole on the bottom of the thumbstick to the thumbstick post.
4. If it doesn’t slide in immediately, rotate the thumbstick until it locks into place.
5. Replace the faceplate and enjoy your game.
