ok guys, I have 2 issues with my other tiller arm I have for my nacra.

The first issue, is it comes out all the way entirely, so if I'm hiking and not careful the whole tiller arm will come out of the other part (it's a telescoping tiller arm)

Secondly, when I loosen it to extend it, and then try to tighten it back up, it doesnt tighten. It just keeps rotating

I'm pretty sure these are not that hard of repairs, but I just wanted to get some opinions before I tried to fix them.
