Out - Factory
In - Valvoline Synthetic 75W90
The stuff I sucked out was pretty dang grungy, but then again, 4500 out of those 10,000 initial miles was towing 6600#'s, so that gear should be good and broken in by now.
Also drained and filled the T-Case. Used Maxlife, just because it says its good for Mercon LV and I have a 20qt box on hand.

1997 4Runner
Out: unknown, didn’t look bad. Not much fuzz on the drain plug.
In: 1qt. Lucas 75w-90, 2 qts. Lucas 80w-90.
Drain plug came out without much heartache, fill plug not so much. I’ll need to get a new one, but for today, I was able to get it loose with a 10-lb sledge and a breaker bar. I put it back on with a reasonable amount of torque.

Taking advantage of the HPL Black Friday sale, I ordered some 75w85 for my '22 Taco TRD OR. Even came with a nice HPL sticker! bonus 
First thing I noticed is that this stuff doesn't smell the same as most gear oil. It doesn't have that "gear oil bad smell". Drained and filled both differentials and now I have some peace of mind.
It still blows my mind that the rear electronic locking differential in my little Tacoma uses about 4 quarts of oil where my 5.7l 1500 Ram only holds about 2.5 quarts.
The front differential on both vehicles holds pretty much the same amount of oil. More oil capacity = better =
Toyota > Ram?? Lol

We just used this in a vehicle the other day. I'm hoping to see some testing on it at some point. Wonder if the new EP stacks up to the big boys.
Did you notice a slight sluggish after using the 75W-90?
