You're not wrong, but personally I'm not a fan of bob tailed motors - they just look funny but I suppose they will go pretty much anywhere if that's your thing.;)

exactly!!!!
but funny dont know about that

Yeah I don't like the look of Bobtailed Range Rover's - if I wanted something that short I'd buy a 90 Defender I guess!

all the benefits of a fender with the comfort of a rr i rest my case(and yes i had a fender)

you dont need to bob tail a gayngie just go out laning once or twice and the arse end will fall off due to the rust !
 
Agreeing with JuicyV8. The point I was making that although both axles are receiving drive there is a small degree of freedom for each shaft to rotate relative to each other. When this rotation becomes excessive that is when one shaft moves at a markedly different speed to its neighbour the fluid is stirred and locks the shafts together causing both shafts to move at the same speed which they do not do on high grip surfaces. The time this takes has improved over the years. Still not as good as a manual difflock.

It would appear that James Martin was talking to TLC, it is TLC not Tic as he states. As he does not agree with my explanation of viscous coupling I will try and simplify it without using to many long words and no four letter ones.
VCU was fitted as standard to many early Range Rovers across the centre differential (not instead of it) automatically to effect locking of the differential when a significant speed difference between front and rear propeller shafts is sensed. It comprises a cylinder attached to the rear prop shaft into which an extension of the front prop shaft is introduced. Discs are attached alternately to the front prop shaft and the inside of the cylinder so that they interleave very closely within the cylinder. The cylinder is sealed at both ends and is filled with a special silicone fluid which has the effect of increasing its viscosity when stirred. So when one prop shaft rotates relative to the other one - the situation of front or rear axle wheel spin - the fluid increases its viscosity enough to lock the shafts together. When relative rotation ceases the viscosity changes back to its original value and the shafts are unlocked. It is all automatic both on engaging and disengaging. The coupling does not interfere with turns as the torque transferred is so small. However, this also highlights a disadvantage of the viscous coupling - no torque transfer will take place until a wheel starts slipping. If you are still an unbeliever may I suggest a look at a book called The Land Rover Experience by Tom Sheppard page 205. He has forgotten more about 4x4 vehicles than most people will ever
know.

TLC i have met Tom Sheppard was kindly invited to join Ryder and Ryders son Kai at Toms house. I'm very impressed a very nice knowledgeable man. Surprised at a few things he came out with but a very nice man.
 
jai lucky old you meeting the great man. I managed to speak to him at his publishing house - Desert Winds - and bought his excellent book "Vehicle Dependent Expedition Guide". A brilliant book covering everything you need to know, including how a VCU works!!
 
having built as many as most people both new and recon i think i have an idea how borgwarner works both classic and p38 which use same viscous ,it does transmit torque to both axles admiittedly this can be less than 50-50 ,its the only link to transfer box for front prop and a vehicle fitted with bw can be driven with front prop removed ,as as soon as torque apllied its locked ,but even in unlocked state it is still contains enough friction to drive
