When out wheelin this saturday, I was told I was leaving a small oil spot when stopped nose up on a steep angle. Wasn't anything severe, and when I smelled one drop I wulda swore it was diff fluid. (the spot was up front a few inches drivers side of center).
I got home and let the trac sit on the clean garage floor and saw no leak (or signs of one). I let it sit and idle for 10 minutes, still not a single drop. I also checked the levels and looked like my engine oil was down about 1/2 a Q, but diff was still full.
It almost acts as if the leak only manifests when drivin in 4x4, and nose up. Think it could be the pinion bearing/seal?
I know I have a small engine oil leak that I haven't pinpointed, but I've only a few drops every now and then.
Ideas where to look or how to find (or should I bother)? What areas are prone leak spots for engine oil (rear main, distrib,

)?
What about the diff?
I'll try to clean it up this week and get under it to look better.
