Craig, I don't know the car well enough, but does that nylon insert have lugs which lock into the drive cups? I had an associated a few years ago that may have had a similar setup, the lugs sheared off so I was never able to tighen the diff correctly and it would loosen all to easily.

Not sure if that helps...
