Why does my suspension not extend?

Hi!

So I am building suspension for my plane, but for whatever reason, it just does not want to extent it is locked in place and only moves about 1/10th of a stud I guess.

I have no clue why this happens, on another plane, with a bigger suspension, it does work correctly and I just copied it and changed the wheel structure.
