It’s pretty common to hear about people replacing their thumb sticks to avoid drift in the future, but I almost never actually hear about people having drift or other issues with the original OEM thumb sticks (outside of the occasional person who broke their stick by dropping the Deck).
I’m also curious to hear what people’s experience has been with replacing the sticks, both the difficulty of the actual replacement, if there were any issues after, and if they think it was worth it.


A couple things to try:
A lot of thumbstick drift is caused from getting debris or sticky residue in around the thumbstick. This is especially common if you let your kids touch your Steam Deck/controllers. Taking some plastic-safe electronic cleaner spray (like CRC QD electric cleaner) and spraying it around the thumbstick while the deck is turned off can fix this pretty easily, and the same cleaner can be used to fix other controllers (especially nintendo switch joycons) as well as sticking controller buttons.
The steam deck has adjustable dead zones. If your drift is very minor, you can increase the size of the dead zones to compensate.
It’s possible to recalibrate the thumbsticks, see this guide
Replacement thumbsticks are available on Amazon, many people like to upgrade to hall effect sticks made by Gullikit or other companies. Ifixit has guides for both the right and left thumbsticks. Important to note with this, there are 2 models of LCD thumbsticks and 1 model of OLED joystick, you need to buy the same type of thumbstick as what your Deck already has (edit: looks like the gullikit LCD stick now works for both LCD types, it has a micro switch on the joysticks to select which type you have). The Ifixit guides explain how to check which LCD type you have. Actually replacing the thumbsticks involves popping the back off the deck (with the microsd removed), disconnecting the battery, unplugging a ribbon cable from the thumbsticks, and then removing a couple screws before pulling the whole thumbstick out. After the new thumbsticks are installed, you will have to follow the callibration guide listed above under #3.
Thank u so much, I’m gonna try fixing it during the holiday
