Here you can get clearer view of how the 6x6/8x8 works.
There the drive shaft that delivers power to the third and rear axle transfer case. the front axle drive shaft is connected to another transfer case, which in turn connected to the main transfer case via flanges (the brake system is on those flanges as well).
Well the title said it all.
We manage to brake the drive shaft the transfer power to the third axle.
The 8x8 - Grasshopper - is now 2X8 only with the first axle.
Never the less - He manage to get out of the Horshan by itself.
