Back on topic:

Brumby i had offroad was great because of the lower weight. I had a 91 model 4sp dual range - two motorbikes on the back doing some fairly nasty driving and it was fine and seemed to have better power and handling.

1800 Wagons - not too bad as well, although you notice the weight and its not as easy to manouvre as a brumby - but its a wagon, its expected.

Currently i have an L series and just took it off road for the first time on the weekend, i was impressed i followed my mate in a land cruiser and the only thing that stopped me was falling into a rut that meant my wheels where off the ground - stuck as.

The L series didnt seem to have as much power but it certainly felt ok driving and like others have said the ground clearance as standard is better than the brumby. Once i get a new water pump in the old L itll be back in the mud again ;-)

Sorry to drag up an old thread!
Just curious why people mention the AWD of the liberty,outback, foz etc as been a disadvantage over the L/MY systems? Obviously the selectable boxes give a 50/50 torque split when 4WD is used. But don't the later models have a 50/50 torque split in first gear anyway?

No doubt someone will correct me if I'm wrong, but to my understnading, EJ manuals have a viscous centre coupling, which functions as an open centre diff, as opposed to the locking centre in L/MY cars. EJ autos have a centre clutch which transfers torque to the rear under certain circumstances, though they can be tricked into locking.

The viscous centre diff isn't an open centre diff, but can act like one. It's basically an LSD - the larger the differential between front to rear drive speeds the more it locks up, transferring more torque to the end with less wheelspin. What gear you are in makes no difference.

L/MY don't have a locking centre, it's always locked, ie: 50:50 torque split when 4WD is engaged (though the AWD L-Series box models did have an air operated centre locking diff - was open when not locked). The L boxes weren't nice to turn sharply on bitumen or similar surfaces :)
