Pinion seal leaking spraying back on the rest?

Water will settle to the bottom, not the top.

I think draining and refilling is a good idea.
Keep that sample and see if it continues to settle, more for curiosity/ future reference.

Just bought some regular Redline 75W90 (6qts) and I am going to do both the rear and the front just for piece of mind. It’s been over a year since last change. I might do the transfer this week as well. I will send the sample off to BL and explain everything and see what they say.

Would that be at the diff/driveshaft connection? If so, not seeing any leaking/spraying from there at all.

Well, here is the sample at 36 hrs later. I can see up close a thin line on top which could be water separation. I am going to drain and refill today. Any thing else I should do? Would a drain and refill 2-3x be necessary?

Drain, refill, operate for a day or so, drain refill and call it good.

I don’t see any water. I’d drain and refill and drive it 12 months. Don’t stress about it either, diffs are super tough and just need oil and they’ll go.

I just drained and refilled both front and rear diffs with Redline 75W90. I also removed front and rear diff breather barbs(?) that screw into the diff and blasted both with brake and parts cleaner. Everything is back together and torqued to spec. I took it for a short drive and there were no issues.
