The note on the papers from the dealer said to moniter the "seepage" of the transfer case and replace the case when the seepage increases. I will look around Denver for a shop that will try to fix this. I also own a Porshe 911 and a BMW Z3 so I am in obvious need of a good German mechanic. If anyone has a recommendation for the Denver area, I am all ears.

I will crawl under the car this weekend and try to get a photo of the "seepage" so others can use it for comparison.
