Mo. I am not comparing to two like for like, one is wear and tear and the other is shock induced as you say.

I am not an armchair expert, having only racked up months as a defender owner. However I am an engineer and understand just how much load, shock or otherwise, is required to snap a shaft of those dimensions. My surprise is that this element is the weakest link of the chain, but that’s Land Rover ownership for you; full of surprises. My expectations would be that the worn splines at the drive member end would give up completely first under shock loading, not the shaft and that the probability would increase as wear increased. This was highlighted to me when I posed the question of my own on whether I go one piece or standard, and seems perfectly logical.

However, as you say you have plenty of real world experience of snapping drive shafts, so you don’t need my views on the subject. Have a happy new year (what’s left of it) and a healthy 2019.

All the best

Sounds like either a change in driving style and/or visit to Nige are in order

OK I'm running 32" tyres not 33" but done some pretty extensive offroading with wheel spinning but never broken a half shaft, maybe I'm just more sympathetic. Not sure I want to find out what my weak point is now I've got pegged Ashlockers, Ashcroft halfshafts, CVs and drive members all round. Probably the gearbox

But then again with three lockers don't tend to spin the wheels. If I am chances are I'm in Scotland trying to retrieve a deer and I'm stuck in a peat bog where there's no worry about finding traction

Col,
That's cool mate.
It's always better that weak spot is somewhere relatively easy to get to 😊

Broken half-shafts don't generally happen on vehicles predominantly used on-road.
It happens laning or off roading where a spinning wheel is suddenly stopped, the bigger the wheel the greater the shock.

If you want long lasting drive flanges, fit a double lipped hub seal, remove the stub axle seal and let the diff oil lubricate the wheel bearings and drive flange splines. Thats how it was originally designed to run. Or just fit one piece

If you want to go mud plugging fit Ashcroft shafts and flanges. You won't break shafts then but you will move the weak spot to a more expensive and inaccessible place. But they are shiny and you will earn bragging rights

Personally I have a pegged rear locker but use the half-shafts as fusible links that will break before something more expensive or inconvenient does.

Good luck with your defender ownership, remember that the drive trains were designed in the sixties to be simple and easy to fix in the field.

Happy new year

Assuming your shafts and flanges are in good condition, I'd say your just as likely to snap a one piece shaft as a 2 piece. You don't see many faures where the splines have been sheared by a single event, more many miles of wear.

The improved manners of one less sloppy splined joint would be lovely! Sadly I have a Salisbury and one piece shafts aren't an option

↑↑↑↑↑↑ @miker What am I missing? My 2002 110 Td5 has a Salisbury fitted and I have a one piece half shaft in the short side and it's been in there a fair few 1000 miles.

I think it's me that's missing! I thought the one piece shafts were only available for the rover type diffs?!

Well then. I suspect mine are worn, guess I have some shopping to do!

IIRC, Ashcroft do a warranty against breakage which I think was either 1 or 2 years.
I think it was 2 years but does exclude fretting. (Understandable.)

What does LR have warranty wise for Genuine, I'd image there is some kind of failiure warranty? TheThunder Rolls🇬🇧🇺🇸
