I just wanted to let everyone know of a problem I had with my transfer case and the solution that worked for me.
About 2 months ago at 37K I got new tires and noticed a clicking noise during low speeds (<15 MPH). It was very difficult to hear due to all of the engine noise. It sounded like a card stuck in a bicycle spoke.
To figure out where it was I jacked the rear up, spun the tires and listened for the noise - it was definitely towards the front, so I jacked the front up and spun the tires - it was the transfer case and very easy to hear if I only spun the properller shaft. It would click about 5th or 6th revolution of the propeller shaft.
The service manual recommended changing the fluid and after reading many posts of folks finding above normal sludge in their diffs, I decided to do all 3 at once.
I am happy to report that after changing the fluid the noise is completely gone. I would definitely recommend changing the front/rear diff and T/C fluids at 30K. I was shocked at how dirty the transfer case fluid was and the amount of sludge stuck to the drain plug. I originally thought the fluid would have lasted a lot longer.
