I was trying to find the source of a little noise when moving the elevator during preflight, and when inspecting the the manual elevator trim cable, I noticed that the rubber end on the metal sleeve (toward the left side of the photo) is starting to disintegrate. (This doesn't seem to be the source of the noise, but the sleeve caught my attention.)
The whole sleeve can be turned (and slid a little, IIRC). The rod attachment to the trim tab is itself secure, and I haven't had any issues with trim while flying.
What is the function of this sleeve, and should it move as I've described?
