If its the same I'm guessing it wouldn't take too kindly to a diesel rinse.
I also believe it is a sealed unit to which this would have no affect

My apologies gentlemen
I miss read the sheet on this thing, I skimmed it and looked at the picture then automatically slipped into ahhh its half an LSD..
Having read the manual properly this time... (nother vote for nuff nuff for me) ID still suggest the drain and flush which will tell you if the thing is leaking out or not, if its not leaked out it shouldnt be failed but will give the impression of being siezed if the diff is also u/s...
given some extra lubricity (ie the diesel)if the diff is stuck then it might free up.(the diff, not the VC
As has been mentioned VCs are sealed so cannot leak out. Most VCs fail due to old age or over work - with age or overwork the fluid inside begins to harden so the VC tends to remain locked - over time the fluid hardens so much that the VC is permanently locked. On current design there is not much you can do except replace.Quote:

All the stators and rotors inside should still be OK.
Unfortunately at this point in time they can only be repaired by replacement.

ummmm........its basically a torque converter [like in most automatic transmissions] but filled with a silicon based fluid that gets hotter when slippage occurs, when the fluid gets hotter it gets thicker and denser and thus allows less and less slippage as it gets hotter and hotter.Quote:

It's a sealed unit and not repairable - but a second hand one with a warranty is certainly worth a try.......or fit a Lockable Centre Diff type Transfer Case instead. if you want to.
Not to mention the very high rate of tyre wear, esp on the front!!
A recent repair in this area took me to Ashcroft Transmissions.
Before you buy in Oz, check what a VC & output shaft would cost landed from UK.
www.ashcroft-transmissions.co.uk, I think. They have a very good help desk.

My viscous died recently, so i converted to a lt230, easyish job and heaps better off road.
Try triumphrover for second hand box and conversion kit.
A little less time answering straight from the text book would help with these errors:wasntme:Quote:

From how I read the manual
It (the VC) couples onto the front drive side of the center diff and the carrier of the center diff to limit but not totally eliminate the movement of the differential gearing.
Ok so that makes it effectively the same as an LSD but its outside the diff... Or have I got that wrong?
If I got that right, If the Center diff siezed would it not also give the same effect as a siezed VC?
If the goop they use in the VC is the same as viscous fan drives from memory doesnt that stuff get thinner with age instead of thicker or were you guys using that as a comparison?
From experience, the VC box is not liking to diff locks unless you use both at the same time.
I had a rear ARB air locker in the 93 Rangie and no front using the VC and it always transferd drive to the fromt more than the rear. This really ****ted me off and I removed it and put the LT230 transfer to replace it, although mine has seized prior to removing the unit. LT230 is much better off-road, it's a positive lock and no reliance on the VC hub to do it's job either. Plus plentiful in supply so you should bge able to locate a good second hand one for about $1000-1200.
In the VC's defense, i did enjoy the whine-free operation and smooth drive but since I use all my Rangies to the limit it wasn't a practical option fior me.
Good luck with it.
