Deja vu. I had the same thing happen. But closer to home. I broke a tooth
or two off of the pinion gear. According to a certain machinist who has vast
experience in Triumphs, these things were notoriously weak. Something to do
with inadequate surface hardening.
At any rate, if you can find yourself a new diff for about $100 you'll be $
ahead. I did that about 15 years ago and it still works great.
Another option is to get Richard Good's Nissan diff conversion. Cheaper than
a rebuild and you get limited slip to boot. But make sure the halfshaft
splines are in good working order, these don't take to axial stress very well.
Sorry about your adversity but it comes with the territory.
Cheers and good luck.
