With the obvious biggest disadvantage as above, especially on steep hill descents, where it may even get outright dangerous, I am beginning to question even the advantages. Quote:

The LSD's are not known to create tyre scrubbing even when used offroad. As the name implies, it allows "Limited Slip" after which condition the differential returns back to its normal state almost immediately (yes there is scrubbing while the LSD is working but that is required to help with traction, without which the whole purpose of a traction aiding device is lost).
Locked Diffs however create scrubbing while being used, but that is under the control of the driver and his judgement of the terrain. Again the locking is done to overcome a challenge, without which the locking mechanism itself is not needed. Quote:

Now what happens to a 100% open differential in a straight line, isn't the torque split equally to both sides? Does it not behave "locked"? Quote:

So if one driven wheel is spinning, the other wheel will get power only when the vehicle is being driven straight (how does it determine that? Steering angle?)
What if you need traction on a non-spinning driven wheel and still need to make a turn (your differential will be open, rendering the whole thing unusable)
So in most cases, this differential seems not so convenient on real world usage (hill driving etc without engine braking) and at the same time, has limited use offroad (as against the usual LSD, MLD, Locking Differential), as it can only distribute torque in a straight line (which on tarmac is anyways available on an open differential also) |
