I went wheeling on Monday with my cousin, we weren't going hard at all. We were then leaving to go to another spot and I started hearing a noise in the front differential. We went back to his house to see if he could fix it but we can't find where it's coming from. When I drive its like bang bang click click click........ All the way home. I had to limp home the other night. It's either the transfer case, front diff, the pumpkin, or the ring and pinion. When the truck is in high it won't go anywhere. And the gears start to grind. Amy tips or ways to fix would be appreciated. Thank you.
