y all are missing something, anytime it is in 4wd the load on the rotating parts is increased= faster wear. i drove 200 miles one day in backroads va, and just kept switching from 2wd to 4wd when needed. u dont have to stop u know...

Did you put your truck in neutral and coast down the hills too? How about shutting the truck off when at you're at stop lights?
