Things You'll Need
Instructions
Turn the controller upside down.
Remove the battery pack from the controller and set aside.
Unscrew and remove all six of the visible screws on the back of the controller with the T8 Torx security driver.
Remove the bar code strip from the controller's battery slot. Remove the seventh and final screw from the battery slot with the T8 Torx security driver.
Push in on the thumbsticks, with the controller still upside down, to separate the two controller halves.
Set aside the controller half that houses the buttons and d-pad, keeping it in the upside-down position so that the buttons will not fall out.
Invert the bottom half of the controller so it is now right side up. You will see both of the thumbsticks.
Remove both thumbsticks by pulling straight up on them. This might take a little bit of force.
Install the PS3 thumbsticks by pushing them down into the places from which you removed the old thumbsticks.
Repeat Steps 1 through 7 in reverse order, beginning with Step 7, to put the controller back together.
