I have a RV 100 Series L/C live front axle with constant 4WD.
I previously had a 80 Series standard with part time 4WD, and preferred this set up and would like to convert my 100 Series to part time 4WD. I am aware of a conversion kit comeing out of Victoria, which converts constant 4WD to part time 4WD. I beleive the viscous coupling is replaced with some type of spool and obviously free wheeling hubs are added.
Does anyone have any information or
feedback on this type of confersion.

Hi tg
Why would you want to do away with the constant 4x4 you have better car control on wet roads and far better braking

Hi Kiwi Ray
The down side is front tyre ware, extra load and ware on front diff and also reduced fuel economy.

Not trying to talk you out of it but is the front tyre wear really an issue ? My Coopers have done over 80,000 so far. I wonder how much you might gain doing the conversion.

Um, pardon my ignorance on the subject, but isn't the Toyota "constant" four wheel drive really only one wheel drive until the centre diff is locked? I thought the 100 series is designed so that it has an open centre differential, and combined with open front & rear diffs this means you could conceivably have drive going to only one wheel until the centre diff is locked. If so, I don't think there'd be much change in economy, wear rates, etc.

P.S. A thousand apologies to all those Toyota people out there if I'm spewing out a bunch of rubbish.

Tyre wear is neglible...if geometry is right
As kiwi says..better handling if left in 4wd all the time....especially if you accidently run left hand rubber off shoulder of bitumen...its a lot easier to get back on and far far safer

I think I would prefer the old school manual locking hubs but for around $1500 (I think) I could easily live with the full time 4wd and spend the cash on Extracors and 3 inch system or a fridge with bag and slide, or a
hf radio (2nd hand) or roller draw for the rear or............................

Howdy Tbone, I would say that on a good traction surface drive would be transmitted to all 4 wheels evenly until one or more wheels lost grip.

you would have to do a lot of km's to break even on the money you spent on a conversion. I have a HZJ105 RV and tyre wear and fuel consumption have never been an issue.
Just how much fuel do you think you will save? The standard 100's I've driven have only been marginaly better by 1-2 L per 100km on a good day.

Hi every one
I run 4 80# all constant 4x4, 4.2 turbo, 2 manual, 2 auto ( i has the hydraulic box the other has the electronic unit)
One truck is my winch clhallenge truck 2 for work and one good one. they all average 11.5 -13 litres / 100 ks I have not noticed any great difference between the auto and the manuals. One work truck gets approx 75.000 for a set of tyres my good truck has just clocked 78.000 on a set of tyres this both city and country driving.
The turbo Lc has a viscous unit in the centre diff and the rear diff is limited slip unless it has diff locks
On the seal you would have all four wheels driving This also helps on componant wear as the load is being shared.
As yet I have not seen any adverse effect from the constant drive, some of my work trucks have been over 400,000 when sold and I have had no transmission or drive line problems.

Hi guys,
Thanks to everyone for the advice. It appears that I may be wasting my time with the conversion.
However, if anyone is interested I did find a conversion kit available from Mark's Four Wheel Drive Adaptors in Vic. Kit price is $899.00.
thanks again,
TG
