They just replaced the seal and they stated they drove it. I drove 1 mile after picking up the truck and now the transfer case sounds like rocks in a coke can. They are trying to state it was already about to go or probably was. Now, I have to fight with the other warranty company I bought just in case GM decided to not cover stuff which they didn't and see if they want to cover a new transfer case now that whatever is going on is even worse than just a leak that was happening before an no noises
