Are front and rear diffs interchangeable?

Good to now know/learning here Cheers Daz mate!
Two sets of opposing crown & pinions front and rear would make for some very cool bunny hop loco street action by the sounds of it :-) Imagine also the pinnacle rocks we could all Lunar Rover elevate over :-)

Sorry for the late reply, just got back from a trip to Lightning Ridge.
Have to rebuild the rear diff because when changing the oil I found metal fragments. Probably LSD clutch plates are disintegrating. No noises though. Also I have 35" tyres and will probably change diff ratios. 4.11 at the moment. Thinking of 4.6's front and rear to give it extra oomph when a hill appears.

G'day Muzza mate. Only my observations but 4.6s on 35s are fantastic in the mountains but mates who have setups like that are seriously considering 5th gear highway upgrades to get themselves to the base efficiently. Currently I run 4.3's on 35's and personally find it a quite fair happy/medium for now.
