Quick question for you all before I start undoing things. From day one my airplane has had a noticeable "clunk" in the nose strut while taxing. Even at slow speeds, every time I hit even a small crack or bump in the pavement I get it
This only happens on the upstroke or when the strut fully extends. I tried reducing the air pressure in the strut thinking it might be over serviced but that made the strut VERY mushy and actually made the airplane very hard to steer. At this point the pressure is correctly set.
My gut feeling is that the hyd fluid is both old, watery and probably less than the required quantity. I believe the strut should work almost the same on compression and extension, just like a normal shock absorber on a car. Certainly the clunk I hear when it over extends can't be good for the stut.
So before I drain everything and try to service it, is this normal? If not, any advice you guys may have for fixing this problem and/or servicing the strut would be appreciated.
