Yeh did Mad Hat Man, thanks...ahem...just 10 pages of the same thread later i've lost the chuffin plot LOL.

What I meant was is there a noise or other physical signs that would give an early warning? (apart from the obvious torque test info & vid),
Ta muchly :)

Is there someone powerful enough to delete the crap out for us? Would make the thread factual, and put it back on topic.
 
freelander was designed so that front wheels go slightly faster than rear as expected that buyers would be used to front wheel drive ,viscous coupling has to work overtime and eventuallt seizes up then allowing pressure to be applied to rear diff and ird unit. ive nevwer known a viscous coupling do any thing but sieze up on freelanders or range rovers,problem with getting exact torque values is that it varies with temp ,and the speed of force acting.if it turns smoothly with a 2ft bar its okay

Unfortunately others have found that it fails in a fail-safe. No drive thru mode as well.
 
my second vcu failed in the non seized way,me and my mate both have freelanders and jetskis and couldnt figure out out why mine kept getting stuck and his didnt,we did the on car vcu test and it always past,it took a while to figure it out that it just didnt engage
 
right here's some actual figures :)

car has 100,000 on it ( assume original vcu)
5kg weight (5 litres water)
1m bar
time taken to move 45 degrees .....



3 mins...

think it may be on its last legs :( gearbox seems to have gone bang anyway, so not suprising the rest of the cars dying
 
sorry if this has been answered and i missed it but im going to do this test as i think i have a problem with mine to my understanding of the unit it works by the fluid getting hot so i was wondering when i think it was hippo that done the vid had he been driveing befor or was everything cold just so i can try and replicate it when i do mine and i will post the results sorry again if this has been answered or a stupid question i just want to get it right.:D
 
Car had been cold for some time. Only just got it out of the garage, where it had been sleeping overnight.
 
thanks hippo i did read the thred i just wasnt sure if it had been covered am i right in thinking the unit works by heating the fluid cos if so this could change the hole thred results if people are not doing it cold?
 
thanks MHM i think thats were i got it from your post i mean ive been reading alot of your post over the last week or so and im learning alot or at least i think i am im new to 4x4s and learning as i go i just read it wrong but thought i should put it on here so every one no's and dose the same thing are you saying that it wont matter if the car has been driven befor the test?
 
I am saying that I dont think it makes any difference....

However, for the purposes of a repeatable test, so that we can get a set of valid results, it would be best if they were all done under the least number of variables ie - cold (as it appears that is how most peeps are testing them).
 
I just done test on mine to see if my vcu was **** and seemed to be about the same time as hippos but looking at his pic my vcu looks like its in two or split???
 
this is a pic of mine its different to the one in hippos vid

oooo thats a bit big you can really see my rusty bits!!:rolleyes: so what is the extra bit? And is it a good thing or bad thing?
 
Hi. Mines a v6 Freelander, which doesn't have the damper. I'll add a note on the video. Lot of peeps overseas looking at it too. Don't want to confuddle them.

The extra bit is a damper.

From the rave disk:

Torsional Damper (1.8 K Series Models Only)
The torsional damper reduces vibration from the propeller shafts. The damper consists of a rubber membrane bonded
between an outer ring and an inner hub. Three bolts secure the inner hub to the output shaft of the VCU.
