2014 5.7 Limited ORA2
Here is the real world test. In 4 high the transfer case will stop sending power to the front wheels when the steering wheel is turned. In 4 low this behavior does not happen. All these tests were done in AUTO mode.I did learn something I had always suspected might be true. That even in 4 LOW, the system is easing up the clutch for turns so wheels don't slip or bind. It's pretty sad that you can read the O.M. and all the Jeep literature and not get one clue how their equipment actually works. You left with hearsay and guessing.
For the O,P. that means what I mentioned about 4 LOW might start trenching if you're turning, that is less likely, but it can still happen in 4 LOW, you just have to watch out for it.
This is the steering angle as reported by AlfaOBD when its straight
This is the steering angle when the wheel is turned
Here is a video I made showing how the transfer case stops sending power as steering angle is increased.
Here is a video doing the same thing but in 4-low. Notice there is no change in the power applied to the clutches no matter what position the steering wheel is in.
You'll notice there is no change in transfer case clutch lock torque in 4-low meaning that steering angle has no affect when in 4-low.
Other food for thought. If you wanted to figure out torque split. Assuming 1710nm is fully locked meaning 50/50 F/R The system always transitions from RWD back to some fwd bias when at low speeds and at a stop. The T-Case Clutch lock torque is usually around 500nm or so. Meaning when taking off from a stop the QDII system has a power split of approximately 30F/70R under normal circumstances (no slipping or WOT throttle).
Since you now know how the torque split works in reality (not just what a manual says) you can watch this video and see how at low speeds and when taking off from a stop there is that 30/70 split and how most of the time the vehicle is in RWD mode.
