Curious. If you do a lot of water crossings have you relocated your diff breathers?

Yes. And the rear still gets water in it. A hot diff, when submerged in 40F creek water, will pull in some moisture past the seals. Not a lot, but it's apparent in annual changes. The front stays decently clean and the TC stays very clean. The rear is gross after a year. My GX also gets worked hard towing.
