Well I went out to the hangar to see how far I'd get with installing my new Sonex 4" wheel and spring assembly. Removed the rudder and access plate, and spring retaining bolt. put a set of vise grips on it and gave it a few smacks... No Joy, not even a 1/16". I'm thinking I'm going to straighten it out, put a puller weight over it and try pull it out that way. Thoughts/advice/experience??
