Clunky G27

Few years ago Logitech decided to substitute its successful G25 steering wheel with an upgrade. Aesthetically almost the same, but internally with some annoying changes.
Logitech engineers did a bad movement trying to avoid the “noisy” G25, upgrading their engines through a new approachment with an awful result.

Thus, there are people screaming and yelling all over the internet about this. If you are good enough with tools and such, you can try to disassembly your G27 following these links and try to fix it.
And remember, you do so entirely at your own risk.
