At first I was going to ask if the weather is cold outside, the grease inside column gets thick and rod drags when wheel is turned ... Then I remembered my visits to Darwin and Sydney Christmas 1968 and decided that would not be a problem today.
Do you have the bushing on the horn rod?

Have not tried to install one without removing the rod though.
