Can someone explain to me the difference between 2 pin and 4 pin axle ! Thanks
4 pin was never fitted on the front, only the 2 pin and only the later 4.6 had the 4 pin on the rear, 4.0 litre and diesel only ever got the 2 pin on both ends. You can fit an 4 pin on the front but it will be noisy as the gears are cut the wrong way. 4 pin is marginally stronger.
You can get 4 pin centers with proper cut gears from Ashcroft Transmissions I think as an option when you buy a rebuilt diff..
The main difference between 2 pin and 4 pin is the diff center. the 2 pin has 2 gears inside the center, whereas the 4 pin has 4 gears - and thus supposed to be stronger as the power/loading on the differential is split across 4 gears internally instead of just 2.
I bought new front and rear diffs a year ago from Ashcroft and they supplied 4 pin rear and 2 pin front.
I queried why the front was not 4 pin and they didn't know, and only supplied 2 pin for all P38s.
HTH, probably not!
Thanks guys, my front has decided to start playing a tune, was expected as when I bought had a seal leak, due to idiot before putting it In on the skew,, was keeping fingers crossed I'd caught in time, but obviously not

That's really weird! I was sure on their website there was an option to uprate the front to 4 pin for an extra cost! Maybe they've stopped doing it now!
When I spoke to them they asked if I had any more info about the 4 pin fronts.
I don't like it when a specialist tries to get me to give them instructions ...... in other words, I could have ordered a 4 pin for the front but it would have been a rear one and my risk i9f it proved noisy.
Make of that what you will!
Interesting that they do show a 4 pin diff centre for the front here: http://www.ashcroft-transmissions.co.uk/4-pin-diff-centre.html
So, I could have had a 4 pin front after all!
