>From what I gather from the VR RUS discord, the two rectangular boxes get loose overtime and wear out the plastic inside that holds the potentiometer sensor, hence cause the drift issue. Pic from Cleric: https://i.imgur.com/eTpxTnM.jpg
>I squeezed some plastic pieces inside to tighten it, and the drifting stop for now, tho I am not sure how well it holds until spending some time with it. Pic: https://i.imgur.com/QbxX0uG.jpg
>The "fixed" one in the photo is for forward and backward, and be WARNED, it will block the strap knots slider (blocked twos that are close to the stick in my case). Also, this "fix" might not work if the plastic inside already wear out too much.
>EDIT: Played with joystick for a couple hours, no drift so far and no deadzone in forward. I imported controllers to Asia and I don't plan to do RMA. If you are in similar situation, it is best to stop using the joystick once it starts drifting and use whatever means to tighten the potentiometer.
