1. Lift the Faceplate away from the controller using the notch in the right side.
2. Next, pull up on a thumbstick to remove the thumbstick from the controller.
3. Align the new thumbstick to the thumbstick shaft, press down firmly until the thumbstick is locked into place at the base of the thumbstick shaft.
4. Replace the Faceplate. The Faceplate will lock into place when aligned correctly with the controller.

SCUF purposely use a one-piece thumbstick which is locked in place by the removable faceplate to ensure the thumbstick does not become displaced on the controller during use.
