Thread: RR viscous centre diff into a D2?

I would have thought that a viscous transfer case would be a step backwards in the off road ability stakes?

The case will 'fit', but IMO it will be a little bit of a pain as you will have to modify tailshaft lengths, and some of the sensors aren't there IE the low range switch that alters throttle response when in low, and the CDL switch to cancel ABS when in centre difflock (With an actuator fitted, of course) The park brake will be compatible, as will be the mounting bracket locations etc as an LT230 can be swapped over relatively easily. It is definately doable, but some mods will need to be done.

As far as off road goes, I would say they are an improvement in some aspects, I never had any problem with mine and sort of wished when I went isuzu in the RRC that I had kept it.
