Tailwheel Question

[DENNY]

It could be a lot of things doing that including just being dirty, poor spring arch, spring loose or at angle. It is best to just pull it apart and see what is going on. Trying to guess on parts is a real crap shoot and they are not cheap. If you do have to order some get the new upgraded rubber seals for the wheel and bottom of the tailwheel they work great!

There is a spring in there that looks a bit like a trapezoid without a base. One ear of that could be broken, or the little notch the ends fit in might be rounded. Easy to replace, except there is a pin in there that gets pressed in/out.

My thought as well.
