I have had my three wheeler for approx 6 years now and never had any problems with the steering wheel at all. I didn't even know it was detachable until today when it basically came off in my hands whilst driving down the drive. I dread to think what may have happened on the road. Anyway I have tried to put it back on and just can't. I have done all of the reading as to why it won't go on but have not managed to solve the problem. I have the wheel aligned because it will go on and engage the splines ie I can move the wheels with it but it will not click to secure the wheel ie it pulls straight back out. It is fairly clean but tomorrow it will be degreased and regreased properly. I can see nothing stopping it going on further but it just won't click securely. Has anyone else had this problem and if yes how did you solve it?
