I still need to have a look-see at the ring and pinion gears one of these days to see how much wear is on them and check the preload on the bearings.
Has anyone priced a new ring gear and pinion gear (that is, if they're still available) from the dealer parts department?

Usually differentials start whining when they wear out, due to an increase in the gap between the drive pinion and the gear. How about putting a custom made adjustment shim between the satellite carrier and the gear to move the gear closer to the drive pinion?
This should reduce/stop the whine and also minimize the "clunk" you feel when you are accelerating and suddenly release the accelerator. The same thing when you park the car and it rolls a bit before reaching the transmission park mechanism.
Any thoughts?
