I have looked at this and this has been discussed multiple times already on this forum and on another, but to save you looking for it the summary is that it is not a problem.
It is not a problem because I am not towing, I am not loading the car up with 5 people and their gear, and I am not regularly moving off from a standstill up steep hills.
In the worst case scenario if I need to start driving from standstill up a steep hill, I can select the low range in my transfer case for that rare situation, and then put it back into normal range after 10 seconds.
Just so you understand, your question implies that I am about as dumb as a human being could possibly be.
To not consider what would happen in first gear with this differential change, that would be really dumb.
You didn't ask me if I had considered it, you told me to consider it with the implication that you were giving me new information that I had not considered.
It is this kind of patronizing arrogant comment that I really don't appreciate.
Ask someone if they know something, do not assume that they do not know it, otherwise you are just being arrogant.
Also if you actually looked at this thread you would see that I had already considered almost everything that was suggested to me, making it clear that I am not an idiot and I have thought this through.
