When you start down that road, where do you stop as it's not just the diff that you need to worry about.

He's saying that they're crap, even in standard vehicles, which rover diffs are, they were stolen from some crappy pommy car slung under a 2 ton vehicle and they do fail

You missed a bit...

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 think you are missing a bit too, if the new diff isn't as strong as a salisbury it's a downgrade. In new vehicles we like to see upgrades (makes you want to buy one) not downgrades (makes you want to keep your old one). In 4WD's we like to see over-engineering, not "if you take it easy it shouldn't break" and if it doe's, "it's the drivers fault". They give the new truck a 6 speed box with ultra low 1st gear for max torque and then a smaller rear diff.......................time will tell

and if Nissan can give us a vehicle with a substantially stronger OE driveline, why buy a Defender ?

There have been far too many reported cases of problems with the P38/Wolf rear end already. The decision to change was purely financial.
I believe the story went something like the UK Defence force wanted to reduce spares inventory (fair enough) when specifying the Wolf, and so substantially the same front and rear diffs are used in that vehicle.
Land Rover were then producing xten thousand vehicles for the Army and so it made sense to specify the same diff on the civilian version, saving lots of pounds (in both ways) on the rear ends.

Bottom line is it is a weaker diff than the directly comparable opposition use, ie. Toyota 79 series, Nissan Patrol or Ford F250.

Yeah, sadly wether its a P38 or a Wolf diff in the rear assuming they're not the same... they still break. At the end of the day there is only so much an 8.5" spiral bevel diff can do and a standard Landy will break them.

There is a good reason my IIa now has 9" Toyota hypoids under it... so I don't have to worry about them.

Why are we comparing Rover to Nissan and Toyo and Ford....

Sound like the Volvo forums....

Because they're stronger diffs

How about a good reason why not???

don't the older Volvo's you used to play with use Dana rear ends Clarkie ?

If it's a D44 I'd much rather that under a Rover than a Rover diff.
The 30 is pretty weak, but has good clearance
