Have you put a GOPro out under the wing to see for sure what's happening? It's
amazing what you might find.

I took an more exact measurement, the 144's were both around .737 OD the 143
was .745 OD. I replaced them with the oversized .780 bushings obtained from
Vans. The 144's were turned down to .7625. The 143 was turned to .7640. This
left me with adequate clearance for the bushings. This also eliminated all
of the play in the nose end of the nose gear, both horizontal and vertical.
The AN hardware looked essentially new, so it was not replaced. The Vans P/N
for the oversize VA-143 is Bush-ST 438X780X1.938 Oversize Bush VA-143. The 144
is posted above.

eliminated 90% of the vibration I was seeing around 14kts. It was not side
to side shimmy, but more of a hobby horse motion with the nose wheel. The excessive
play must be exacerbating the resonance. It's not totally gone, I only
felt it during the first taxi when the tire had a flat spot. After landing and
taxing back it was essentially gone. I need to have a few more flights to
pronounce it cured.
