That sound isn’t exactly normal, but I don’t think it’s a big problem. I’ve had a problem like that on a Sanwa JLF I owned before. I think it’s one of two problems:
- One of the parts inside of the joystick (probably the metal washer in between the joystick main body and the spring holder) is dislocated.
- It’s just your spring and there’s nothing you can do about it anyway.
If it’s the former and something’s dislocated, it should be easy enough to fix. All you have to do is open up the stick, remove the joystick, take it apart, and reassemble it. You can do this with a standard Phillips head screwdriver, a flathead screwdriver, and a set of pliers. Just be careful not to be too touchy with the parts that have lubrication on them. You don’t want to be taking any of the lubricant off. After you make sure everything’s set properly, put it back together, reinstall into your case, and enjoy.
My problem with that JLF I owned a while ago had to do with the spring. I don’t know what it was about my particular Sanwa JLF or what, but the spring wasn’t “right” so to speak. It still functioned fine, that is to say it still made the joystick return to center properly no matter how I moved it. But it constantly made this weird scratching sound whenever I pressed up. The joystick still worked like an absolute champ though and the friend whose stick I installed it in said that he hasn’t had a single problem with it.
I can’t say for sure which of the two your problem exactly is, but it should be a fairly easy fix if there is something wrong with it. Hopefully that helps. :tup:
