VCU, IRD, what the...?!

Thank you misingL ...i read the document...and yes the test seems to be very dangerous...it can be tested by a mechanic on a lift bridge...anyway, the document is very interesting
 
Incidentally I did own many years ago (don't laugh) a FIAT Panda 4x4. That had a dog clutch between the front and rear propshafts operated by a handle in the car, only to be used on loose surfaces. Dead simple!!! Now how can I mod a VCU to do the same??

This has been discussed on here before:

I even contacted Ashcroft and got a somewhat hopeful response, it's in the thread above.

While we are on the T3 Synchro topic, there is an aftermarket product which gives a synchro selectable 4 wheel drive. I think it is in the same thread as I just posted.

No news since though...
 
Two things interest me

1. Newer tires should be put forward or back?
2. Does this test shows the validity of VCU and whether the results are correct?

"Vcu torque test results
What I did
Chock front wheels
Hand brake off
In first gear
Jacked off side rear wheel up
Take centre cap of wheel
Set my torque wrench to 300Nm with 32mm socket on the end
Placed on hub nut and turned wheel (wheel and vcu turned ok)
Tried 200Nm wheel and vcu turned ok
The lowest setting on mine which I could turn the wheel ( vcu )was 75 lbf/ft 101nm
My fl as done 80k miles I was quite surprised that not much torque is needed to turn the Wheel (vcu)
You must remember when doing this test that the wheel (vcu) will turn slowly when using 101nm
Even at greater torques you can’t expect the wheel to turn fast
Just set you torque wrench to 101nm 75lbf/ft and apply constant pressure and the wheel will slowly turn round if you try to speed it up your torque wrench will click
I am quite satisfies my vcu is ok and in good condition
hope this helps somebody ".

mmmm, we test the VCU's on a bench on a rig that we built ourselves that uses weights and is timed. Trouble with measuring torque is the way it is applied, you get a high torque figure the faster the load is applied. If i stand on my breaker on a rear wheel it take about 5 or 6 seconds for the wheel to rotate enough for me to fall of it when i test s good VCU. Sorry not very scientific, but thats not the way i test them normally!

Don't worry Hector, i understand that. I'm not going to name them or say anything else, its just blindly obvious when you test them back to back. I'm not saying its not possible, but I would like to see a non modified one that had failed as i can't see how it happens, unless the VCU casing has cracked or a spline gone??? I've seen plenty with only rear wheel drive that drive like they have a rubber prop shaft!!![/quote]

How is it possible to only have a rear wheel drive freelander using the VCU setup? to accomplish this you would have to remove the front drive shafts?
