Stop in for a cup of coffee

Remove the strut rod nuts. And the LCA nut.
Then if the hangup is in the front hex (in the LCA) the t-bar will move to rear.
That should help get any remaining tension off the hexes.

I can think of the three things that can cause them to hang up.
* damage to the front that side loads the t-bar
* painted hex ends. Don't ask me how I know not to paint the hex ends.
* corrossion.
