>What are the possibilities of the whine then? The outer bearings are brand
new. Could it be the front bearing about to give up?

It takes a concerted effort to set up a differential to NOT whine. As the
ring and pinion gear teeth wear down the tendency is to whine. The
bearings may still be fine and the unit may continue to function for years
this way. But it may annoy the heck out of you.
As in any gear box, the action of the gears means that gear teeth are
continuously engaging and disengaging and it is only as a result of close
attention to details and the helical setup that they don't whine more than
they do. Just like an engine, full of oil with rotating shafts sticking out
each end, doesn't leak any more than it does. The second law of
thermodynamics tells us that the oil wants to be all over the road and the
bottom of the car.
I suggest you watch it closely for a while and if it doesn't get any worse
then don't worry (unless the whine starts to get on your nerves).
