I love the notion that LR would assist. You have to put a tie on to go into my local dealer and Jon the parts bloke - who is always very helpful aside, they very snooty. Always wonder if they will ask me to park around the back. FL1 kicked off the SUV revolution and LR has never looked back - what has this to do with topic, I dont know?

When I say "help" I mean sell us parts we can drill holes in to get the magic goo aht

I assume we would need to flush out the old crap and inject the new stuff. Then plug/seal. If the plates insode were broken then it would fek up so a known working VCU turned into a HCU would be best.When I say "help" I mean sell us parts we can drill holes in to get the magic goo aht
What about the Haldex off FL2 with an on/off switch?

I was under the impression the haldex had reliability issues. Lots have been changed and I think a bearing was failing or something which caused a lot of warranty repairs. Someone will be along to confirm.
The HCU is a nice idea. If simular has been done before, then LR must have thought about it themselves i guess.

If we look around hard enough, I'm sure someone will have some fluid for sale. It's only a certain type of oil and Carbonyl iron powder, just got to find the right stuff. Plus the movement of the vanes would keep it nicely mixed up.
The only thing is that your lines of flux must be perpendicular to the angle of resistance - so from the front of the HCU to the back so that the strands of mangetised particles are interferred with by the vanes.

Mine like me visiting! I think they actually like my dog more tho! I leave her with the receptionist who feeds her the posh biscuits that are meant for the range rover owners and next thing you know she's on her back legs in the air with the salesmen rubbing her belly! I look like a scruffy ****, she charms them

Audi use the magnetic Goo stuff in their suspension units too. It should be fairly straightforward to get hold of some.

Ha Ha, love it. The receptionist gives me that look that means don't get within 10 feet of me - I'm sure she very nice but main dealer bashing is all part of the fun of LR ownership. What is funny is that you have to walk right thru the showroom past all the shiny metal to get to parts - give me a side door and will happily use it!!

Bed time reading.....
Design Analysis and Experimental Evaluation of an MR Fluid Clutch
If you are considering an MRF type application, then a product by BASF - their Basonetic MRF5020 seems to be most suitable - NOT Damper fluid which is a different animal - categorised by BASF MRF2040.
There may also be a problem when the material isnt new, in that because the fluid does not comply with a true brownian principle (the particle size is too big) it could possibly form a sediment over a couple of months. This is not a problem when new as it is readily re-dispersed. But might be if a vehicle was laid up over winter.
If any of you are maths wizards then MR fluid behavior in the shear mode can be modelled by the following formula:
Where = shear stress; = yield stress; = Magnetic field intensity = Newtonian viscosity; is the velocity gradient in the z-direction.

Who's on her back with legs in the air, the dog or the receptionist?

The receptionist, legend tells that DD is a sexual Tyrannosaurus.

For many years now we Freelander 1 owners have suffered with VCU problems. Things should have got betterer with the Freelander 2s electrically engaged rear diff, but that has had problems too. I stumbled across this some time ago when the video first came out, and cant help thinking it could provide a good solution to fix our treasured 4x4s.
The video below is one of many LR produced showing the design and technology of the Evoque. Part of a clever mass advertising campaign on the web. The link jumps to the bit where they explain how the adaptive suspension works. It uses a technology called MagneRide which uses a magneto rheological fluid (oil like) which has bits of metal (think small iron filings) suspended in it. When an electro magnet is placed near to it the viscosity of the fluid changes from soft to firm. The demonstration shows the difference when a permanent magnet is placed next to 2 syringes which pass the fluid between each other. The magnet makes it harder for the stiffer solution to travel between syringes.

This would be an ideal replacement solution for a VCU. The HCU would be a VCU (with the usual plates inside) filled with the magneto rheological fluid and an electro magnet located near it. At the flick of a switch drive to the rear wheels would be engaged. Hence enabling 4x4 drive when we need it. It would also be possible to vary the stiffness across the HCU by varying the current supplied to the electro magnet to allow for a smooth lockup of the HCU, to reduce transmission shock when 4x4 drive is engaged. This would also allow a partial 4x4 system with a reduced torque applied to the rear wheels for road use, if required. A signal from the traction control system could activate the electro magnet to lock up the HCU when 4x4 drive was required.
No real moving parts.
Electrically operated using magnetism.

Is this what you looking for????????
