I have one lying in my "garage" from a 1989 5kQ non-turbo.  Dead as a ...
doornail?, and it stinks ;-) (the oil)  Seriously, it's very worn out -
sharp gears on the crown, etc.  Not mine, oil leakage was missed or ignored.
  The PO said that it was making continuous noises - whining, not banging.
One bearing was shot, so it's possible pieces to fall in and sound like you
describe.  I'd say look at the oil, if black maybe change it with GL-5 and
drive again to hear it.  Chris at Force5 offered us such a price on a used
one, I'd replace it if any doubt, as the PO had to do anyway.

BTW, my  filler plug (on a 1988 90 Q) was stuck, so we took out the whole
round cover and drilled, cut and so on the plug.  This way you can look at
the diff somewhat - back of the crown.  The covers were exactly the same on
both cars, even same part ##, though the housings were different.

Good luck, Tihol
