DulaShock 4 CUH-ZCT2 Potentiometer(s) Replacement

Introduzione

When using a joystick, it moves two brackets inside the analog stick in rotation and each of these brackets are attached to a potentiometer. The main function of a potentiometer is to measure the rotation and precise movement of the joystick. One potentiometer senses left and right movement while the other senses up and down movement. Inside the potentiometer there is a metal wiper that is attached to a white mounting bracket. When the bracket moves the wipers where it contacts the track changes which registers the joystick's position and movement. When malfunction of a joystick occurs, it is mostly due to the wear of the potentiometer. Over time, the wiper scrubbing back and forth against the resistance pad creates imperfection.

This guide will show you how to replace a damaged potentiometer from a DualShock 4 Controller (PS4 controller). The format for this guide can also be applied to a DualSense Controller (PS5 controller).

You do not need any special skills to perform this guide.

As for where to buy the potentiometer replacement, I recommend buying it from Amazon. The link I provided for the potentiometer replacement in the tools section is costly, you can find more cheap options from the Amazon website.
