You are right. Its always the Left stick that fails first. And this controller is 11 years old. So it has taken its beating of fair use. My RIGHT Stick is perfect condition. About these analog sticks sold online. Are they genuine like Sony put it in original DS3? I don't think so. I think they are knockoffs like those in 3rd party cheap controllers. I don't think they will perform as smoothly and efficiently as original DS3 analog sticks. I guess best bet is finding dead DS3 controller, extracting its RIGHT analog Stick which will likely be in good shape and use it to replace LEFT analog stick to my working controller. But too much headache i think.
