If it's a bad enough dirt road to bump you off line then you do need to either slow down or 4wd hi can help, but what speeds are you doing? As mentioned earlier you can supposedly do 80 in 4wd hi, which means it's been designed and tested higher but I think if you can go faster than 80 in 4wd the road is probably not rough enough to need 4wd. Am I talking in circles?
Also you can change to 4wd hi while moving, but I think you have to do it while travelling in a straight line as your wheels need to be travelling at the same speed.
At the end of the day the road needs to be bumpy enough, or have enough loose gravel to allow the wheels to travel at different speeds and release any diff wind up.
I've been told that after being in 4wd, jack up a wheel and see if it spins on it's own which is the 'wind up' releasing itself. Not sure how true this is, but if yours did spin then I would suggest the road has too much grip for 4wd and you need to slow down.
I have used 4wd hi on a number of sandy corrugated roads and have had no problems.
