QUOTE (WingMan Team Bulletin Board)

I used a little bit of lubricant and applied to the axial point of the joystick and so far the problem had not appeared.

*Warning: Doing the described procedure will void the warranty. My gamepad's warranty is long over so I can do it without worrying.

This is how I did it:
1. Open the base of the gamepad.
2. Unscrew the two silver screws on the PCB and lift out the two pieces of PCBs.
3. Both analogue sticks are the potentiometric joystick (a.k.a Potentiometers). Use some force to pull out the analogue sticks cap. You will see two 1.1cm long metallic sticks.
4. Apply some lubricant very lightly and in small amount (or you can use WD-40) to the axial points of the stick which is inside the metal casing.
5. Move the stick around and you can see the white rubber material rotate as well. Apply lubricant to the other points that are visible.
6. After applying, move the sticks around so that the lubricant flow into the joints.
7. Close back the casing.
8. Use the Windows control panel calibration tool of the joystick to test out the effect.

Hope you can make it work too.

I'm an electronic technician and I can tell this is a common problemes for dirty pots to make controls work unproperly.

BUT!!!!! DON'T USE WD-40. It's gonna work well for a while but as soon as it is completely dry, it will start acting more like glue than lubricant.

INSTEAD, USE CONTACT CLEANER! You can buy that for a few dollars at any RADIO SHACK or electronic store. It's especially made fore cleaning pots and swiths, it won't jam like WD-40 will do.

I've followed the steps and it works great. I dont need to unplug the control every 5 minutes anymore. If youre scared, dont be! Follow the pics and itll be very easy. One thing youll need to get is some Contact/Control Cleaner & Lubricant(which is easily found at radio shack or other electronic store):

1. Open the base of the gamepad. There will be 7 screws to remove, one is hidden behind the "QC Passed" sticker:

6. After applying, move the sticks around so that the lubricant flow into the joints.
7. Close back the casing in reverse steps.

BTW I believe this can also be applied to regular PS2 controls if its also erratic. I still need to do this to mine cause it always pullls one way now.

Enjoy hours of gaming again!
