When using low range 4WD in fourth gear in my 2010 Nissan Navara it constantly surges, so bad that this gear is unusable. It only does it in this gear. Nissan told my dealer that it's a characteristic of this vehicle and a better option would be to use high-range second gear instead. I rang Nissan customer service and was told the same thing. What do you think?
I agree with the advice you've been given, go up to high-range and get out of the problem area
