So .. Changed oil on finaldrive, IRD and manual gearbox. While IRD and gearbox oil was in perfect condition, the finaldrive oil looked like metallic paint :s, so seems like my VCU still works after 206K km, but the final drive is doomed...

It's likely that the VCU has gone stiff causing the rear diff to fail. If you change the diff and not the VCU, the IRD will fail next.
I'm gonna do the VCU test today. It will at least give me an indication of the condition. But when I change the diff the VCU will be changed as well. No need to take any chances..
