just the strength of diff gears and case 2 pin is actually one shaft holding the 2 diff planet gears ,4 pin has 2 shafts or a cross shaped shaft holding 4 diff planet gears, diff carrier is also a lot stronger

Sincere thanks to everyone who replied to this.
I'm going to pit a 4 pin diff on the front now.
Chequebook out!
Cheers.

Make sure it is a front diff you can't stick a rear one in the front.

Oh Boy, what next? 
So, I have to be very careful how I place the order with Ashcroft; if I ask for two 4 pin diffs, I might get two rear ones?
If I ask for one front and on rear, I will get a 4 and a 2 pin!
I'll think on ....

rears do fit in the front its the crown wheel and pinions that are handed, though if you fit a rear cw/p in front it runs on rear of teeth like disco or defender

Right, if I understand, the diffs are interchangeable physically, but the crown wheel and pinions run differently?
What does this mean? Is this a bad thing?
Cheers.

up until p38 lr used the same cw/p front and back ,the one in the front driving on the rear of the teeth ,whether thats an issue depends on usage similar with 4 pin, though a high mileage cw/p isnt going to like running on opposite side of teeth

obviously you are best getting the correct ones if you can ,but it is possible to run rears in front
