ive been lookin at the super diff and have a question

does it still use that thurst ball crap? i think it is very stupid.. but o well

and also i was wondering... when it sais 1/2 after fully tightened how do you dertermine fully tightened? when you cant turn any more? when it feels hard to turn? what do i hold to keep it from being tighetned too much? its very confusing to how tight it actually has to be..

when the diff is tuned right what is it supposed to do? move freeely? or should the diff be stuck and not be able to move or what? if someone could explain this to me id appreciate it.

sorry if my post makes no sence but i understand it...
