why is it that diffs still fail when you are driving sedately?????
today, nice warm day, cruise up to the post office, go for a bit of a drive since it's pleasant outside...
then,....
clunk....clunk....clunk....
bloody crownwheel loses a tooth 
i know exactly why it happens (as far as fatigue and cycling and the prior 3 years of overloading:P ) but it still mystifies me as to why it happens when you are not doing the usual silly things...
ahh well, just bitching as it's annoying this close to christmas...
grrrrrrrrrrrrr

"all i want for christmas is 2 spare diffs"  la la la laaaa

It should have been, "all I want for Christmas is my crownwheel teeth".

Ahh - that happened to me once too, in my Datto 1200 Coupe! Many years of abuse and burnouts, then driving sedately and notice a whirring and clunking noise. Thought it was the exhaust touching the body, continued driving for the day. I got home, had a look under the car and 2 of the 4 bolts holding the tailshaft on had been sheared off. Put some new bolts in and drove to my uncles work for him to look at it. 2Km's from there it goes BANG, and then BANG BANG BANG so I pull over, have a look, it appears OK so I driving the remaining 2Km's. Turns out that one tooth had sheared off, I'd kept driving and then the next one snapped, hence the loud banging.
Totally buggered - diff housing was full of metal bits and the Crownwheel and pinion badly damaged.

LOL  didn't think of that
hmm, i still have them, they're sitting at the bottom of the diffhousing  ..
i don't think even Krazy Glue can fix this one....
not anywhere near as funny as draining the gearbox oil and having 10 teeth fall out

sounds nasty... i wasn't even sure what had happened at first.. it really just sounds like there is half a thong stuck to the tyre, and it slaps something as it goes round... so not overly loud, and not jolting forward movement like when the gearbox goes..
actually, i gave it some stick in 2nd gear just as i got home and the noise was much quieter than when freewheeling! weird.
i jacked it up and the clunk happens every second turn of one wheel, so has to be crownwheel....hmm, wonder how long it would last

jeez stewart, that JB weld stuff's pretty strong...
just squeeze some on the broken tooth, and shape it with a bog-filler rasp before it goes hard...

my boss was telling us a similar story the other day
he went to willowbank in his 480hp XW, towed his brothers HZ there {not road legal}
when he raced it, it was fine then as he went over the line in the falcoon, it made a odd noise, when u turned around at the end it made the locker noise, ee, ee, ee, ee.
he did 2 more runs and said fuck it, lets go home, towed the HZ home {30k}, reversed the trailer up a 30m driveway and as he put the trailer in its spot "clunk" no drive
