My plane is a 1974 Warrior, and for a while now I've been hunting for the cause of an annoying nose wheel shimmy. I've done quite a bit of research, and I think I've tried most of the easy things and now I'm stumped.
Indications:
Moderate speeds during taxi, nosewheel shimmy can be felt in the pedals
Same on rollout after landing
Fixes:
Slight pressure on one rudder pedal or the other seems to negate the shimmy temporarily
What I've done so far:
-Replaced scissor link bushings and bolts
-Checked preload on wheel bearings
-inspected tire for scuff marks or signs of deformation
So far, no change. So the question is what comes next? Replace the shimmy damper or are there other things I can inspect/verify first?
