My understanding is that for front and rear axels to turn at different speeds the transfer box must also act as a diff. As in landrovers. The diff lock on a landrover locks this diff thus meaning front and rear axels turn at the same speed. The front and rear diffs allow wheels on the same axel to turn at different speeds even if the centre diff is locked. The Jimny transfer case enables selection between 2wd and 4wd. When 4wd is engaged the front and rear axels are locked to turn at the same speed. To allow ythem to turn at different speeds it would have to have a centre diff. Thus the transfer box on the jimny in 4wd position is the same as a Landrover transfer box with centre Diff locked. To get full time genuine 4wd lockers would need to be fitted front and rear to both vehicles.

The earlier Zukes, like SJ's, never had centre diffs. As you say, the front and rear axles then turn at the same rate. They don't have the facility to turn independantly in 4wd. For this reason, they mustn't be driven in 4wd on tarmac because the transmission 'winds up'. Just like driving a Land Rover with the centre diff locked.... a definate no-no on hard surfaces.
When in 2wd, the front propshaft is disconnected from the gearbox thus allowing different rotational speed between the axles for raod use.
The axle diffs only allow 'differential' rotation across the axle and don't make allowance for differential speed of the two axles as you correctly point out.
Not sure about the Jimny though. It may well have a centre diff.
CNorman:
I have a funny feeling that i am about to be proven wrong here then... :oops:
Are you saying that the Suzukis have locked front and rear axle speeds and can not run independant of one another? I did not realise that.
If that is the truth then suzukis have genuinelly gone up in my estimation.
P.S. My understanding is that Suzukis do indeed allow different front and rear axle speeds hence the not "proper" four wheel drive reference i made to them.
:cry:

Although Jimny's use a different t/fer box the theory they work is the same as SJ's and therefore when 4wd is engaged the front and rear prop shafts rotate as one. The half shafts can rotate independantly via the front and rear diffs. Only thing stopping a jimny is lack of ground clearance. I'm now on 31" tyres, any bigger means serious body sugery. :cry:
CNorman:
Well i definatly stand corrected and can see more how the Suzukis are regarded off road.
My next concern would be that they would not be as "man" as land rovers off road.
Mind you, i bet 31" wheels clears some ground, that is actually larger than landrover if i am correct
