Raas,
The 'book' on any aircraft will say many things that do not translate into real life flying. They are often written by engineers. I have many years and thousands of hours of airline flying and one thing I have learnt is that when the 'book' comes up against common sense, common sense wins.
Indeed there may well be a procedure to get the u/c down by moving the rudder. However the person who devised that one clearly was looking at trying to dislodge the u/c by some means. As the pilot you have to consider how kicking the rudder will effect the rest of the aircraft. You don't just do it because 'the book says'.
