Controller Thumbstick Problem

[josh313]

Hello, my I noticed a few days ago that my thumbstick makes a thump sound except for the normal clack sound when I hit the outer-casing. So I inspected it and noticed that the rubber dome part of the stick hits the case except for the middle plastic part.

You can tell that on the right side there is a little gap between the rubber top and the plastic middle.
But the left side the rubber part touches the outer-case, very noticeable during play.

I opened up the case to see if there is anything in the actual board that's causing it. Couldn't find anything...

I also tried to change out the case and stick, still caused the same problem.

If anyone knows whats going on and can help me fix this ill be a great help! Thank you

If it's a problem that just recently started you may have messed it up with an extra hard flick. If it's always been like that/it's a new controller my guess is that it's a manufacturing problem and you should just get a different controller.
