Gamestop G3 Gamecube Left and Right Trigger Replacement

First, remove the 6 screws in the back panel and pull the back panel off.

Separate the halves of the controller. However, be careful when separating due to the little wires that could get mixed up.

Next, remove the rumble motor by unscrewing the 2 screws connecting it.

Finally remove the screws holding in the right and left triggers. It's easiest to hold the trigger together as shown in the third picture. Remove both the left and right trigger, and then you have successfully removed your back panel.

Remove the screws holding the plastic bumper cover in place and remove it.

At this point you should be able to remove the bumper along with its spring from the controller.

Clean thoroughly underneath the bumper and remove any dirt or debris before reattaching.

To reassemble the device, follow these steps in reverse order.
