The transfer case on our crewcab dually started leaking recently, took it to the dealer and there is a brass bushing inside that supports a shaft and if the bushing wears enough, the shaft can wear a pinhole in the back half of the case. That is what happened in our case. Dealer says it will cost $850 plus tax ,not very happy about it!!
