I finally gave the burro an inspection today, after OCG. My passenger side Spicer is no longer stationary. It spins around, but it still locks and unlocks the axle. The drivers side does not spin around. I took both apart, down to the inner wheel bearing, and could find no differences. Is the rubber O ring supposed to fit tight enough to hold the hub selector in one position? BTW, this is a D44 axle with later model Spicer lockouts.
