Ok.. before I start I never wrote this tutorial it was written by sicknasty413 I just thought it would be quite nice to build the tutorial section up a bit.

Supplies
Nunchuck
Tri-wing screwdriver
Small flathead screwdriver

Step 1
Finding your Nunchuck:
..It looks like this.


Step 2
There are two screws. So whip out your tri-wing screwdriver and get to twisting!

Step 3
Just like the wiimote, the nunchuck has 2 clips in the front. You may need to use a flathead to pry a bit, but I didn't have to. I just pulled until it came off.




It'll look like this with the top half off.

Step 4
The nunchuck internals/PCB come/s right out. Just pull up on the PCB. The wire can be a little tricky to get out. But just keep pulling upwards and wiggling. It'll come out. The analog stick also pops right off. Just pull up on that as well.




There you now have a disassembled nunchuck
