Ok tried to search for this topic but could not find anything detailed. Basically I know our 3 differentials limit slip to wheels that slip...lol the 08 has Helical front and torsen rear LSD and of course our trademark C.diff.

Anyhow I'm just wondering why when I jacked up 1 wheel (front wheel), just 1 wheel, I could spin it, shouldn't the LSD in front limit the wheel without traction? Could it be because it's based on torque transfer and not rotational rate difference? I really want to know why it spins.

You basically have it. Remember, despite all the trick lsd's they don't have enough locking factor to account for a wheel in the air. This is why it's bad to lift a wheel during apex of a turn (as in from too stiff a rear bar on the older cars).

Helical differentials act like an open differential when there isn't positive resistance against both wheels. There is no lock. They Helical diffs use hypoid work off of the torque actually being applied to the ground from the faster spinning wheel.gears to bias the torque between the 2 wheels. The gear designs creates internal torque multiplication based off of the torque applied to the ground from the wheel with the least resistance. They bias torque only under acceleration.

The only downside to this design is if one wheel has no resistance; ice, wheel in the air, etc... That's why you can lift one wheel and freely spin it. Its great for a street vehicle, because it makes for smooth low speed turns and drivability.
