Working it out at Moreland's MX in Stanton, MI, I lost drive to a rear wheel. Never good, I climb out to find the axle loose and clinking in the inner cup on the left side. A teardown shows the cage lost a piece, allowing a ball out, which allowed all of them to roam. Unless I find one easily, the 3rd machine will start to loose parts. As things go, I'm glad that it was the inner cage and not a axle or outer CV, as being an ATVR long travel, the the inner stuff can be swapped out from a stocker. Time to pull both cups out of the trans as long as they're apart.
