The crownwheel and pinion are installed as a set, and create a wear
pattern (contact patch) on each other after many years and thousands
of kilometres. Once the differential has been dismantled for repair, it can
be difficult to get the contact patch exactly matched. That is the usual
cause of whining. Same thing applies if you only install a new or used
pinion to an existing crownwheel.

Worn or loose (lack of preload) pinion bearings can cause whining, and
even just a worn out crownwheel and pinion. If the gears appear to be
in good condition, you could try adjusting the contact patch, or just put
up with the noise, and hope that it settles after a while.
