Razer Wildcat thumbsticks not coming off

Hey, I have a Razer Wildcat controller that is experiencing some weird stick drift issues. The left stick is all over the place and I have a suspicion that it is the carbon layer that is worn out (whole stick needs replacing) but I want to see if I can fix it without de-soldering the analog piece but the damn thumbsticks won't come off. Are they glued in place or what?
