Interesting event

Just as a matter of interest, has anyone EVER had a front propshaft to axle flange drop out of thwe axle and bounce on the road ... fortunately at very low speed?
After removing the shaft, I found that the retainng nut, which holds the flange to the diff, was rattling around inside the still-attached propshaft flange, and felt as though the threads were intact.
I've had Landies for over 40 years, and this is a new one on me!!
To compound the issue, she fires up immediately and then dies, as though she isn't gfetting any fuel.
Any suggestions?

Put some fuel in

She has a full tank, and it is fully bled through, and had a new fuel stop solenoid fitted last week.

Maybe the prop bounced and hit a fuel line or part of the fuel system.

Someone I know had the gearbox end of the shaft come free at speed and trash the footwell.He was lucky to have been wearing a steel toe/sole work boot that save the day.

Front diff pinion castellated nut has somehow lost the split pin and worked itself out, thus dropping the propshaft on to the road with the nut and washer inside the flange!
I have never known this to happen!
Was it the fault of the garage, I wonder??
They were the only ones to have removed the propshafts when they changed the gear and transfer boxes less than 400 miles ago!
Has anyone else shared this experience??

split pin would have to be there with nut and washer,but its not odd that the nut could become loose

No, it's not odd. That's why a spilt pin should be fitted cos they are known to work loose. Maybe the garage forgot to fit the pin or didn't bend it over.

Thanks for that @jamesmartin but surely that would be as a result of bearing wear and pinion and/or thecrownwheel teeth wearing over a long period, and movement/play could be felt from quite early on?
As a matter of course I would check for play and adjust either at a bi-annual service, or whenever a propshaft has been removed, and woould not expect a caatastrophic failure after 400 miles!!

bearing wear shouldnt effect flange nut becoming loose,the inner races and shim plus spacer are still held tight on the pinion regardless of bearing wear on the outer parts, although shock loads which will be greater with slack due to worn bearings etc on take up or overrun will eventually want to loosen a nut fitted too loose or split pin missing, id guess its likely someone had diff flange off at some point

Many thanks for that @jamesmartin , you have confirmed my thoughts regarding the removal and the possible wrong refitting of the diff flange.
