Any amount of differentiation causes the clutches to drag, as they move relative to each other any time the axle shafts are not turning at the same speed.
The "drag" is so minimal it is inconsequential or non existent - oil separates them and technically they do not touch. When they are not locked up there is nothing holding them back - they just freewheel. Other wise they would wear out quickly.
They do not get engaged until a ratio is met. Not even a little bit and it make no discernible heat.
What makes heat is heavy loading and lots of power - or abuse.
Personally I would never own a truck, especially a 2WD, without some form of LSD. Had one once and got stuck in the most ridiculous places.
