I must start with, I have no idea if this is acutally a problem. I have been offroading numerous times. I was out yesterday and comming up a fairly large rock when i was losing traction in the front, now i know that when you lose traction in the front it catches and sometimes causes you to bounce(which isnt good) so i apply the brake and try again, sometimes tapping the brake lightly to fool the differential to think that one side is getting traction, but the problem that i heard a few times was a loud clicking from the front which sounded like the front diff, just wondering what it may be. Sorry if i rambled here a bit much.
