Ummm.. make sure the Knob is not loose and turning freely. We had the
same symptoms, loose knob slipped "in" on the shaft hard against the
panel, so could not push the shaft in to uncage the gyro, so it coud
not be "set". Slid knob back out to proper position on shaft, toghten
set screw, fixed..

Maybe?

Well, it looks like my directional gyro just went belly up. When I went for
a ride today, the setting knob was very sticky, and then suddenly not sticky
at all as it now rotates freely and doesn't feel like it is engaging
anything. The gyro card does not rotate with the knob.

I have a Cherokee with a heading tracking Autocontrol III autopilot.

What are opinions regarding having it rebuilt as opposed to replaced?

Thanks
