Sorry to hear about that. I am the guy mentioned earlier w/ the Frontier that blew a diff. It was my spider gears. I was going up a hill w/ the locker on and the right rear tire was off the ground. I had a little bit of wheel spin and when it hit the ground the gears just broke into pieces. I limped it in to the dealer. They blamed it on the blocks and I said that doesn't make the spider gears break. I called the Nissan consumer affairs and got no help. They said they would not cover it at all. It was gonna cost $2600. I went to the owner of the dealership and talked to him in the showroom w/ customers around and told him to put in writing how the block caused the failure in the rearend. He said he would work on it. The next day I got a call saying they were going to cover it. He couldn't figure out a way to put it in writing so he called Nissan corporate and got the approval.
