Van's recommends 20 lb. break out force for the nose wheel RV's. Free
castering will guarantee nose wheel shimmy.

Thanks Joe,
The front was rebuilt and the nut was taken off. The guy who did it
said he tightened the nut to firm stop then backed off a half turn. It
does swing very freely. I had a suspicion that might be the case.
Thanks,

Mark,
I chased this problem for several years after the first few years
having no issue. The easiest and most effective solution was just to
simply tighten the bottom pivot nut. Mine is tight to the point that
the center return springs just barely return it to center. In fact it
may not return to center if it is static sitting up off the ground. It
does center in flight and it does center during taxi operations.
Hope this helps
Joe

After several months (actually since late January) I flew N886MJ again
today. The new owner who lives near me had been doing several
modifications such as installing dual controls, adding a gascolator,
installed a right left fuel selector as in a Cessna, new brake masters
and rebuilt front axle and bearings and changed the fuel pumps to a
parallel set up and some non mechanical changes. Anyway, it was a
great feeling to fly N886MJ again. Everything the new owner did
checked out good. The only problem was that on landing the front wheel
shimmied which it had never done before. We will be taking the
assembly apart and going through it to look for wear, etc. Any ideas
would be helpful. Like I said the previous 643 landings never even
produced a hint of a shimmy.
