You may need to disconnect one end of the rudder cables to remove
tension in the "S" to allow the tube to be pushed back into position.
It would be a good time to thoroughly inspect the cable for wear or
frayed cable end sticking out that may have slowly pushed the tube out
of position.

Mike,
You need a way to get some pressure on the nylon tube and force it back
into the 'S' tube. You might try clamping two little wood blocks on the
cable where it exits the nylon tube (held in place with a 'C' clamp), then
heat up ehe 'S' tube with a heat gun and then pull back on the rudder pedal
adjustment. The wood blocks won't let the rudder pedals move, but will
place pressure on the nylon tube, forcing it back where it belongs
(hopefully)............... give it a try, it's better than replacing the
rudder cables in order to get the tube back where it belongs!
Cheers,
JJ
