John,
I have seen this exact problem on several Alpine diffs.
When I changed out my diff a few years ago, I found that most of the
crown wheel
bolts were a tad loose. The rear had whined a bit, but no damage to
pinion or crown was seen.
After removing the loose bolts, most of them had shattered like glass
across the threads. All the fragments came out without problems, and I
installed new bolts to replace the old ones.
It seems that these bolts may have been tempered just a little too much,
and were
very hard, but equally fragile.
If your rear changes pitch on you suddenly, clunks or if you have it
apart, dont mess around, and replace those bolts!
All you have to do is pull the axles, then pull out the third member.
With the right tools
the procedure only takes about an hour.
BTW, Ramon Spontelli, recently found out he has a gutted rear end from
losing some crown wheel bolts, so this can happen to even the nicest of
guys/gals.

These old rear ends do tend to whine a bit - although if this just
developed it may be worth looking at. Sure wheel bearings, but bear in
mind that Alpine rear ends have the habit of bolts coming loose on the
crown wheel in the diff. The coming slightly loose is usually prior to
the more expensive sounds that surely follow. This may be a warning of
things to come. Might be worth checking.
