You did not clarify who or what is 'only for us', after all there is Pathfinder (R50) 1996-2004 called Terrano II in markets outside North America and Pathfinder (R51) 2005-2012 called Pathfinder worldwide for standardization.
The R50 Pathfinder/Terrano was a completely different vehicle as it is constructed in unibody format as opposed to the ladder chassis of the WD21 Terrano/Pathfinder. Diesel engined vehicles were only available in Japan and Europe.
When I seen others mentioning the Terrano II, 720, D21, D21U, WD22, D22U and R50 I understood the question was about Pathfinder v's Terrano in general.
I am unable to give an answer on the issue of front diffentials.
