Then you won't damage the transmission by installing it, but it won't be 4WD either.

I'll keep you in suspense until May time, when the weather is warmer.

Ye iv just been reading them, very good write up(other half is starting to think I'm having an affair I'm reading that much on phone last few days)
Worst comes to worst I could go down ur route and replace carrier bearings. Would have much to lose if it turned out to be a bad one, I need the props anyway

I don't know if anyone does VCU refurbs in Eire and the postage to send a VCU to GB and back might be prohibitive. If you could do it yourself it could save a lot of Euro. If you can operate a drill and a figure out how to use a tap then DIY is totally do-able.
The first time I used a tap it was when refurbing a VCU.

It dosnt look intimidating at all, have my own little workshop space in shed with appropriate tools, just have to gather all the bits and bobs for job. I'll have to give the post another read for specs againI don't know if anyone does VCU refurbs in Eire and the postage to send a VCU to GB and back might be prohibitive.

VCU's which turn too quickly will be caused by:
Filled with "lesser" type of liquid than it should have.
Not enough liquid.
Not enough metal plates.
Metal plates put back int wrong order/pattern.
Over the years we have discovered some vcu's which turn faster than eggspected. Re-conners do this to ensure their VCU feels betterer to drive when yer get it. Also reduces strain ont transmission so it reduces the risk of yer transmission snapping with their VCU and less chance yer complain if that dun't happen.
Some were just filled to make them weak and useless and sold as they dint care.

VCUs have been known to fail “Mondo mode” - ie with no drive thru the device, but that is not common.
Also , as Hippo says, some uncrupulous refurbers have been known to sell “2wd” VCUs, with no guts in, so it looks like a good VCU, but does nothing.

No. It's not May yet. I'm going to be trying to revitalise my VCU, which is now timing at 50 seconds. I'm hoping to quickly and cheaply get the timing to under 30 seconds, while keeping it working as it should.
I ment to do it last year, but life got in the way, and bizarrely the VCU timings reduced by 10 seconds, which would have skewed my quick and easy experiment test results.

I think the polish chap from years ago who tried to convince us our vcu's can fail open circuit or at least reduce resistance across them over time or through use... was a cleverly setup spoof account. I can't remember the login names but there was him and another who popped up a bit later to confirm the same. With no leaks and nowt snapped tis not possible with they said had physically happened.

Ask @mondo. It was his dads that failed like that, hence the term.

For a VCU to fail open circuit something has to break or the fluid has to leak out because it is impossible for it to get thinner with age.
Half of the discs are attached with teeth to the outer part of the drum and half to the inner shaft. The Freelander drive train isn't strong enough to break the teeth off so I suspect any VCU failing open circuit has lost its fluid.
