Things You'll Need
Instructions
Turn off your PSP, removing the battery cover and battery in the process. There are five screws that need to be removed in order to loosen the PSP cover, which is what is covering the analog assembly.
Remove the two screws underneath the battery. Place those screws to the side. Remove the two screws on the opposite side of the battery. Remove the final screw on the bottom edge of the PSP. Keep the screws together, making sure not to lose any of them.
Grip the PSP on both sides and pull it apart to remove the PSP cover. You will now be able to see the analog assembly. This can be removed simply by popping it out.
Once the analog assembly is out, you can place the new one in and replace the cover. Tighten the screws and test out the PSP to make sure the new analog joystick works.
