    freelander irds are weak ive been through my 3rd one now same as rear diff (im on my second) but thats still running currently i am running stock m47 but with a bigger turbo i am going to do an m57 swap soon im pretty sure i can use p38 m51 transmission (good for the low range) i can use this standard transmission that im running now but the irds just shear so often is there another ird i could use? a stronger one also is there other diffs i could use like limited slip ones or more modern ones that i can fit a diff locker too? my car is specifically for having fun on trails not road use running no sway bars for extra flex i have a 60mm lift kit on too also looking for softer shocks for more flex any recommendations? if i get another ird such as one with a transfer box could i remove the vcu so i can choose what wheels the drive goes too and have it completley locked 4x4 in the sticky situations,

    thanks

    M47R is an inline four originally mounted longitudinally in a BMW although it mounted transversely when it is shoehorned into the engine bay of a freelander. The M57 is an inline 6 mounted longitudinally in every application where it is used. This thread reminds me of people telling me I needed to drop a (straight 6) supra engine in my MR2 (which has a straight 4) in that it simply will not work. If you want to give your freelander a massive performance hike by means of swapping out running gear, I'm going to suggest you look at Audi tt running gear.

    There is absolutely no way you could get an M57 and a P38 HP22 or R380 into a freelander.
    You'd also need an Ashcrofts adaptor kit for the Hp22 to M57

    If you are breaking that many IRDs, then it's quite obvious that the VCU is fubar, and needs replacing.
    How are you going to get an in-line 6 cylinder engine and transmission in the space where an in-line 4 cylinder engine and transverse transmission go?
    It isn't going to happen, not without a complete change to the drive layout.
    Do you actually know where the IRD is, and how it works? It's already locked in 4x4, as it's takes drive directly from the gearbox, sending it to the integral front diff, and out to the rear, where the VCU controls how much drive then goes to the rear diff.
    If you're breaking IRDs and rear diffs, then it's nothing to do with too much power, but the fact that the VCU isn't allowing any slip, which is overloading the whole drive train.

    If it's just for fun, then surely you'd be better off building a one off special, which does all you want, without the constrictions of modifying a what is effectively a family car, with some off road ability.
