The Elastomerics on the 169 are pretty stiff and help with self centering a bit. I'm trying to think what other tail rotors do for self centering if the control linkage is broken and I can't really think of anything.
Remember, the servo got disconnected. No point in centering an item that isn't part of the control system anymore.
Nooby yes the elastomeric are stiff. However they were overcome by the servo, last in-it being made was power pedal, disconnects from the control rod and the valve remains open and motoring to full deflection.
