you do know in that link you sent me it has a Chart that show Actual Front and rear Torque being different At different locking rates? which says in a nutshell that YES the torque gets moved around.
Did you even read that or did you just post it thinking 'ya i'm right, and this proves it' ? cause it proves you wrong.
It also has a lot of wrong stuff in there things like 'if your traction will only permit 100 ft lbs of torque to be put down with out wheel spin the engine never produces more than 100 ft lbs of torque. Wow that's so wrong i don't know where to begin. If that's how physics worked no one would ever spin their wheels because as in that explation your motor can't produce more power than your wheels can put down (WRONG!!!!)
maybe they meant you can't transmit more torque to the ground than your wheels will permit traction wise and when your motor produces Over that amount your tires spin.
If you Re-read that article Carefully it says when a center diff is fully open the torque split never changes, But if you can Lock it some how... than it does.
