A fiberoptic inspection scope allows you to look inside and check the bolt heads.
I have an old one that is not good enough for patient use but was good enough for that-- mine were OK

Tom,
Does the car rock back and forth a long way while in gear? Mine did,
and it unfortunately turned out to be a very, very rare diff housing
failure. Mine cracked, and I never mistreated the transaxle (no
dropping
the clutch, no drag racing).

Sometimes, broken bolt-heads will stick to the drain plug magnet or
come
out while draining the ZF- which slould be done yearly! Note
you
run
the risk of destroying your ZF if one of the broken bolt heads
gets
caught in the ring & pinion mesh. At the very least, the bottom
cover
will be cracked as the bolthead squirts out at high velocity. At the
worst, the whole case will open up like a walnut.... In a recent
Newsletter, there were photos of an owner who found EIGHT broken
bolts
(out of ten total). This has been a well known problem since the
Pantera
was still being built. Mangustas were factory safety wired
but
very,
very few Panteras.
The two 11-1/2" long cross-bolts through the bearing
side-plates and
the lower cover keep one from removing the lower cover
while the ZF
is
mounted in the car. And even if it was somehow
removed, removing
sheared ring gear bolts with no heads and properly
torquing new
US-made
bolts in place, then safety wiring them all the
while on your back
under the car, is not an easy task. Remove the ZF and
do this on the
bench.

Have
always heard an occasionally clunk when I'm waiting at a stop
light
with the car in neutral.
Thought it was a bad universal joint, but
checking them seems to show
they are good & tight.
I now think
that
the ring gear bolts are loose or that one or more of
the bolt
heads may have
sheared off.
They have not been safety wired.
Is there an easy way
to confirm?
Look for shaving on the bottom drain
plug on in the gear
oil?
Can you remove the anything while it is in
the car to confirm?
Tom
