is it possible to post a picture of the two diffs?
I got a bit "lost in translation" (pun intended)
thanks

From memory 4.0 litre and diesel had two pin diffs front and rear. 4.6 four pin rear and two pin front. Went to four pin front and rear with 4 wheel TC. Others stayed same. Service exchange units for older part numbers are available from Land rover at the usual silly prices. But only one new diff is listed TBB000270. Listed for both front and rear use so i take it that will be four pin.

Just saw this on Ashcroft's site which kind of fits in with what I've read before about an unofficial cross-over period from 99.
Ashcroft Transmission: "All 99 onwards (Thor) P38s 4.6s have a 4 pin front diff as standard, the 4 litre cars retained the old 2 pin until they were out of stock and switched to the 4 pin front diffs too mid 2000ish onwards in both cases the upgrade was required to handle the extra loadings introduced by the 4 wheel traction control system which came in with the Bosch engine management system. The 4 litre Thor (Bosch EMS) had a 4 pin rear diff from the off."

Just booting it on a slippery surface with (braked) TC gives the diff serious stick! Especially if it's snatching from side to side transferring enormous amounts of torque instead of just spinning it away. Probably why LR quietly dropped the two pin when four wheel TC became standard.

a cheap method of using the abs as a locker, instead of putting a locking front and rear diffs like it should be

It gives the planet gears more work and load. But to be fair for normal road use will possibly very rarely be used if ever.

Well "some" would be wrong then! I'm sure a handful of two pin diffs probably got fitted to the wrong vehicles but 4 pin diffs became the standard in the end and were definitely what were fitted to 4.6s - front and rear post Thor.

You need diesel torque
But even the lowly 4.0 V8 has more torque than the BMW 2.5TD, the 4.6 more so and the 4.6 Thor in a different league.
