    I did the breather mod on my rear diff last summer. No issues... I think.

    Maybe two months ago I was checking out the rear diff/leafs/shocks etc, and noticed some oily/dirty material around the base of my breather union. It has me wondering whether diff fluid is leaking out of the top of the diff (is this even possible with gravity?), or whether the crud is collecting there by chance. There is dirt all over, but my attention was drawn to the breather. I cleaned it up when I noticed it, and it seems to be back.

    It does smell like "used" gear oil, but the quantity (about 2 sq inches coverage) is so small that the leak would have to be very tiny.

    Could fluid be leaching up through the threads?

    Thoughts please.

    OK, I'll check the hose for kinks. I didn't use teflon tape... maybe I'll throw some on. Thanks.
