Me... I'm talking about a standard vehicle.

Yeah - let's talk standard vehicles - and compare a STANDARD Nissan patrol H260 rear axle with a STANDARD ROVER.

Nissan ute has a 120ish" wheelbase and a 1 tonne payload capacity
Land Rover 130" ute has a 1.5 Tonne payload capacity

Nissan has 1.51" 37 spline axles (halfshafts) and HYPOID diff with a 10.5" diameter ring gear.

Rover has a 1.24" 24 spline halfshafts and a SPIRAL BEVEL diff with an 8.25" ring gear.

Sure the nissan is semi-floating, but the overall package is still about 20x the strength of the rover diff.

Many of us on here are engineers and know what goes into design and testing - so no need for you to get on your soapbox. I would give Keith (Revor) the job of designing the rover drivetrain over the whole team of LR engineers any day.

EDIT - and it is obvious to all LR owners who have any engineering knowledge (as well as people like Mal Story) that LR have made SEVERAL retrograde steps in drivetrain/axle design over the years. That is why many people fit AEU2522 CVs (or equivalent) or RRC stubless CVs and 24-spline front ends in place of the later model CVs and piddly 1.1" 3X spline shafts that LR decided to fit in their infinite wisdom.

Many of us have seen parts fail - both in when used offroad and after seemingly no provocation at all - you seem to be claiming you are the only one with first hand knowledge... I broke a 10spline Series halfshaft in a stock 88" driving DOWNHILL ON-ROAD. The vehicle had never been "abused". Mal told me about a customer of his who picked up a brand new (stock) extreme, had ARB lockers fitted, and decided to take it offroad for the first time to try it out, and broke all 4 halfshafts in one day!!! Sure he may have been "abusing" it - but the drivetrain should be sufficiently over engineered to take some abuse on stock-sized wheels. The nissan I mentioned in the example above could take the abuse all day and then come back for more.

Land Rover 130" would that actually be 127"ish ?

The other thing that is a good comparison between Land Rover and Nissan - is that as soon as you are west of the Ranges - it's Toyota country.

Unfortunately for us we need the parts and service network more than most of the previous Nissans.

P.S.: We used to have UD (Nissan Diesel) trucks when the family distributed ice cream and frozen foods and they were the most reliable of the bunch. Isuzus, ACCOs, Bedford, Dodge, Leylands and even Austins in the dim distant past.

Yes 127" - nissan is about 118" or so, but AFAIK the different models vary.

If you want to use a cruiser or a hilux in my example above - it isn't too far off the nissan.
80/100 Series cruisers and hiluxes both have 1.31" 30-spline axles/halfshafts. Only difference is hilux is SF. Hilux has 8" ring gear, but it is HYPOID so it is way stronger than the rover item. Cruiser is about 9" or 9.25" from memory??? and also HYPOID.

BTW, the H260 Nissan diff is fully floating too, and has flanged axles.
I think it's the H233 that's the semi floater, the one in the rear end of wagons and coil cabs utes. All the GQ through GU leaf rear cab chassis have the monster full floating diff.

So again we get back to our mates, the good ol' pommie gits, doin' in effect worse than nothin', fallin' asleep on the job, aint unusual, and sending out shyte quality stuff to the good ol' Aussie mate.......................it's only sour grapes.......... Cricket.....Union......

Jeeezzzz... and you call us a load of Whingin' Poms??

Just for you lot, I did some digging today.

Basically, what's fitted to the back end of a Defender now is NOT the old Rover diff that you all know & love... Instead, it's actually a newer unit, where the design is actually based on the Wolf diff. I suppose you could almost say that "it's a Wolf in sheep's clothing".

M

We only whinge with good reason, but far too many beers were sunk in the seven hours between those two posts......


......I'd suggest that the jury is going to be out for a while, and that a revision may have to be made, along the lines of: 'A sheep in wolves chothing'.

it's still only a spiral beval unit, and so lacks pinion teeth engagement compared to a hypoid diff, and so is inherently weaker for the larger tyre diameters, high torque multiplication of 4wding.
