This weekend I was going camping with some friends and to get into the site you had to climb a few hills. They were pretty steep and loose but nothing crazy. I put it in 4lo with the rear locker on just to be safe. Halfway up I heard a super loud pop and then a horrible noise anytime I tried to give it gas. I backed down and checked underneath. CV shafts look fine on both the hub and diff side. Then I looked at the diff and there was fresh grease all over where the front drive shaft goes into the front diff. There was also a chunk of metal on the ground underneath and slowly dripping was gear oil. Luckily was able to limp out in 2wd to the street and call a tow truck. I’m hoping this is an isolated incident because I didn’t think these front diffs are known to be weak and the hill really was not that crazy.
