So about a week ago when driving in about 6 inches of snow in 4wd i would hear this very noticeable "bang/pop" sound accompanied by a large jolt. it would happen every minute or so driving in a straight line at a constant speed. it felt like the truck was loosing power momentarily. After some thought and discussion i suspected that the problem was in the T-case, possibly the chain slipping because it had stretched out. I found nothing wrong with the T-case but i have very limited knowledge of it so i took it to a specialty shop. they said everything looks fine and suspects that the problem has to be in the differentials (probably the front since it happens in 4wd). my question is, what could possibly be causing this in the differentials, or anywhere else for that matter. my best guess is that something is binding up and when it lets loose it makes the noise and jolt sensation. any help would be appreciated.
