I found that the nylon feature of the nut barely engages the threaded
pin. By looking at the nylon in the nut, one can see that there is only
a very faint impression left by a thread. When assembled, the nut is
just flush with the end of the pin. I was taught that there should be at
least 1 1/2 thread protrusion, so I guess I ignored my own rule in 2017.
I will try a nut with a deformed thread style locking feature plus
Loktite. If still not satisfied, I could drill holes in the pins for
cotter pins or drill holes in the nuts for lock wire.
Yes there is no rotation of the bushings or pins that contact the nut so
I guess the loosening was normal vibration over 20000 miles.
Thanks to all for responding.
