obviously as they stiffen more strain is put on the tyres and transmission ,i read the bit about never seeing one seize ,maybe on freelanders they dont need to reach seized before damage is done and rr takes a seized one for some time before front diff goes ?

The first person who designs a gauge ,that fits in the dash and gives real time readings of VCU resistance and temperature over a journey wins a fiver from me.
If it could also save this data and be able to analyze it for comparison with previous journeys ,another fiver will be awarded.
Probably cheaper to just change the VCU though.

there was guy on here a few years ago that was trying to make a mechanical "dog clutch" type of system. dont know if it was successful... a lot of slitties use a similar system, but electronically controlled. they dont seem to have problems!

i've certainly opened yet another can of worms over the vcu subject, personally, i feel the only course of action that can be taken for peace of mind is to replace the damn thing that has seriously eaten into my rock slider fund:Cry:, must bloody grumble ( & i will )

as said before, dont panic. just check it regularly, think of it like checking tyre pressures and fluid levels.

Mine is approx 20 seconds with 6kg on it to turn 45 degrees to the horizontal, as per the red line below. Approx 80 seconds with 2kg. Bar length 1.2m The weight of the bar was 5kg for those who wish to take this factor out. Mine is a 2001 v6 with original GKN vcu. Tested at something like 20k miles. Recently repeated 2 weeks ago with same figures. My full results are on ere somewhere. But I will put up the full set again to re-confirm, within a week.
NOTE: this is called the "one wheel up test" and is displayed in this video:
Freelander 1 2001 v6 Viscous Coupling Unit VCU Torque Test - One Wheel Up Test - YouTube
More results will follow after I've watched me video's again. Also results for the same vcu tested on a bench on it's own.
Proof of vcu activation and reaction times when trying to spin wheels on snow, already filmed ready to put up for analysis. Just need to edit the video and slow it down a bit. Thats for the same vcu as above.
