AS per my other post about differentials I seems to be getting classic symptoms of a siezed viscous coupling.

The problem is that it passes the jacka wheel test and drives just the same with the front drive shaft removed.

So what else can give the same symptoms? IE tyre scrub, jerky steering etc?

I guess one of the diffs could be jammed, though I don't really know how.

Assuming you've reinstalled the front prop shaft, lift both front wheels and just make sure that as you rotate one of them, the other rotates in the opposite direction. Then repeat at the rear. If you have a jammed diff you won't be able to freely rotate the wheels.

Other than that, I really don't know what to suggest.

Yuo didnt mention if you checked it cold which I assume you did, if then I would carry out VCU test when hot....

Also has the vehicle been on a wheel alignment system to check for correct setup, careful here as some places will say "Its abit over but not serious" ........

I have had the front wheels ff the ground and front diff seems OK.

As I have to leave it for the wife and go to work I have changed the shocks. The noise is still there but it is more stable. Am I just addressing the symptoms instead of the cause?

I tested viscous cold and hot, although I would have thought the same symptoms happening with the front prop removed pretty much negates that anyway?

Alignment not checked for a while but its not that far off - to make it this bad I would be in the ditch!!!

I really am out of ideas now - the wife is taking it to the local indi next week but I am not at all convinced they really know the P38, I need Chris (viperover) on holiday in the Cape as most indi's down here only really understand defenders.

OK thanks for the two guys who tried to help but the wife is taking it in tomorrow for a "specalist" to look at.

I still ahve this feeling it will be the center diff but I can't understand how it carries on with the front prop shaft removed

Dave. I will be back home on wed if you want a second opinion before taking it to the "specialists". I have got a recond transfer box on my work bench that I will be fitting sometime that you can take a look at to help you get your head around what the different shafts should do.
