Nintendo 64 Analogue Stick Repair
The analogue control stick on a Nintendo 64 controller is fantastic when it's brand new, unfortunately over time they can be loose and un-responsive. Luckily though, it is very easy to fix.
Remove the nine screws from the pad, not forgetting the 2 little screws in where the memory card/rumble pack goes (a magnetic screwdriver will help a lot with these screws). Once you've got the back off, you'll quickly see the unit which controls the analogue stick, it's held in with 3 silver coloured screws.
Before you undo the 3 screws, disconnect the analogue unit from the main circuit board, then carefully remove the Z-Button, gentle pull each of the clips apart and ease the button out. Once it's disconnected, undo the 3 silver screws, leave the black screw for now. Whilst you've got the pad in pieces, if it's covered in dirt you may want to remove the circuit board and leave all the remaining plastic parts soaking in warm soapy water.
Now it's time to take the analogue unit to pieces, undo the single black screw, then pull each of clips away from the back, again - be careful not to break them. The unit comes apart in two halves, study each one so you know how to put it back together!
Your unit may contain lots of white plastic dust, once you've taken it all apart you should blow the dust away, or if necessary wash it in soapy water.You'll see 2 black "bits" (I've not idea what to call them), with teeth on one end. You'll notice the curve is bigger on one than on the other - the bigger one belongs in the bottom half of the unit, the smaller one is attached to the stick in the top half. Twist the black "bit" and the stick until the black "bit" comes off, and you can twist the stick some more to remove it from the unit. The spring and white ring will now come away.
