Wow, checking in to follow this.

Any updates?

[viscous coupling new info]

I've done a lot of reading up on viscous couplings recently:

VW used them to drive the front wheels of their "synchro" vans. They have many of the same issues with tyres etc as Land Rover Freelander VCUs. VW Viscous couplings can leak (not a problem for LR VCUs) causing no drive to front wheels, or gellation of the fluid causing constant drive (as with LR).

From: http://www.syncro.org/VCTest.html

There appear to be two primary causes for the VC to engage when it should not: (1) having tires that are not all the same size and wear (all 4 must be the same), and (2) age...VCs appear to have a nautural life span, at least where subjected to routine high operating temps.

Also, I would wager the below (form the link above) is the primary reason for LR Freelander VCU failure, especially as the early vehicles gearing meant the unit was constantly slipping and hence heating the fluid:

A typical scenario leading to a cooked VC would involve a syncro with tire sizes that vary slightly in treaddepth. The syncro is regularly driven at highway speeds for hours at a time over a period of time. Eventually, the driver notices binding in the drive train whenever she pulls off the highway into a gas station for gas. It may be subtle at first. Eventually, though, as the fluid gets cooked and ruined, the wheels seem to stiffen or bind much easier than before, and ultimately at the slightest turn of the wheel. When it gets bad, the drive train may lock up completely in the parking lot at very slow speed upon a relatively slight turn of the steering wheel. This total engagement of the drive train puts tremendous strain on the components of the drive train when the van is moving at speed under power. With continued use, the transaxle soon fails, the drive shaft and CV joints are also strained.

See also: http://www.vanagon.com/syncros/technica/ for some more info.

It would appear Land Rover VCUs (like VW) suffer from "Gellation" where the fluid spoils and goes thick, causing transmission wind up (perhaps due to the unit constantly accounting for the mis match in gearing). So even if a car passes the "VCU test" of jacking up and turning a rear wheel, the fluid may still have spoilt to a certain degree and be causing a load up of the Diff and IRD - i.e. its not totally solid but is dragging.

I suppose the test should be changed to "if the rear wheel is hard to turn" - you would need to compare a new VCU to yours to tell - if yours is harder to turn then the new VCU it might be on its way out. But I would like to see other evidence like wear patterns on tyres and the reverse skipping tyre test. I would say going by the expense of new IRD and diffs then prevention by fitting a new VCU to a car that has the reversing issue and scrubbing rear tyres would be wise.

This does negate the common belief that if a Freelander is used off road a lot then the VCU will be healthier - unless of course regular "cycling" of the fluid helps keep it in good condition, but I do not know enough of the chemical composition and properties of the fluid to comment on this.

This link indicates it is possible to refurbish a VCU: http://www.vanagon.com/syncros/technica/vc-expert-interview/index.html You can imagine drilling out the fill points on the VCU, blowing the fluid out with an airline, fitting brake nipples or similar and refilling with fluid. However it seems the sticking point would be locating a supplier of the correct fluid! We have no idea of the exact composition of the fluid Land Rover used.

These guys refurb them and sell for £200 - they must get their fluid from somewhere - but £200 seems pretty reasonable if they have a warranty:

Hope this info helps people understand the VCU!

[Legalities of converting a commercial (van) to car?]

Hi - I'm after a Freelander 1 and an option I'm considering is buying a TD4 commercial (~£500 cheaper to buy on ebay than a car - even when adding VAT). Insurance for SDP and without any business or load carrying use comes in at £100 cheaper than car versions. I used Compare the Market and changed it to say it has 5 seats. Commercials seem to have regular main agent servicing rather than hotch potch local garages of cars. Also theres a chance it will stay taxed as light goods so cheaper tax.

To fit a back seat to a commercial I presume I would need the seats, mountings, trim, windows and catches from a breakers. Thats easy.

What about informing the authorities - is it as simple as changing details (number of seats) on the V5?

Has anyone done this?

[Freelander Interiors]

It's had in interior swap. The black didn't start to come in til 2002. I hate the early interiors as well, the 5 doors are a wee bit better tho.

Hi EggNChips - thanks for confirming that. Looks like I will have to put up with the interesting interior if I go down the early car route. That W plate freelander had gone by the afternoon so I didn't have a chance to get a good look at it, I suppose it could also have been a private plate.

[Freelander Interiors]

Looking to buy an early (pre TD4 gen) Freelander as they are so cheap!

However the interior colours are a bit challenging.

I've seen this challenging combo:

This is slightly better:

Leather option:

I assumed this was all the choice I had.

The TD4 generation (2001 on) brought in this slightly toned down version:

And the black cloth:

Now I really want the black cloth interior (most practical seat colour, and less offensive acid blue in the dash) but I haven't seen any pre 2001 cars advertised with it! However this morning I saw a "W" reg 3 door in black with the black interior parked at work. W makes it 2000 - so has this car had an interior swap or was black available as an option?

I know I need to consider the car mechanically as much more important than interior colour, but if I can find a nice car with black interior I would go for that.

Does anyone out there know the interior options?
