Johann, what he said about the Patrol diffs is true ......They are MASSIVELY over designed....... however looking at this from a different angle.
Diffs do break on Cruizers ( not brand bashing, this does happen ) and the difflocks survive. Diffs don't break on Patrols. There is a lot of negatives about the Patrol standard diff lock being weak !! Yes it is, but I'd rather loose a difflock than a whole diff. If you put a kickass difflock in, that is designed to take some serious punishment, then at some stage something has to break if the forces are too much. Now seeing that the Patrol diffs are so strong they can take more punishment, which makes the driver push the boundary a little further, which the diffs handle perfectly, but then you push a little more...... and a little more..... and a little more..... and then there is one almighty bang ads your diff explodes after taking 4 x more punishment than a Cruizer diff could have handled....
Just saying...... Find out how many Cruizers have popped a front diff, in either forwards or reverse, with difflock on and off.
Its a nice to have but a lot of money for something I have NEVER had the need for, even when I ploughed through 600mm deep snow in Lesotho...... or mud in Botswana pans..... or beach sand in Mozambique and Atlantis dunes ( and I drive a diesel !!!)
Wimpy had an ARB Airlocker fitted to his Patrol...... but I still went up "Hells hoogte" at 3 Provinces a few seconds after he went up ( yip it was a little more difficult for us rear locker guys )..... but we went up !!! but that is for extreme stuff
