I have an 06 4x4 with 59k on it and i'm in the process of changing out all of the fluids. Today was the transfer case's turn and when I took the drain plug out maybe 6-8 ounces came out. I took the filler bolt out and jacked up the front in and still got nothing but a few drips. I may be off a little but I doubt I got 2/3 of a quart out. I've only had it a month or so but have never had a drop of any fluids on my garage floor and as sat there for 3-4 day at a time. It defiantly took the 1.7 quarts the service manual said it would to refill.

1. Where did the fluid go?

2. Why did the fluid go?

3. What possibly could cause the transfer case to lose fluid?
