I was having some noise in the rear differential. Drained all the gear oil and added the 85w-140. So far, no noise

Working great. Changed every 30k miles.

Good oil but almost %300 higher in cost in such a short time. What’s the explanation for that?

VALVOLENE quality at a great price.

I've used this in some Chevy vehicles, a 2000s blazer and a Tahoe in the rear differential. This was easy enough to use without having to use an extra extension spout. I like that it comes with a cap to save more for later. In my particular situation, the fluid had dripped out from a drain plug on the diff housing that was not sealed fully. This caused an audible "roar" in the rear end. So what I did is I put the required amount of this fluid in the differential and also added LiquiMoly MOS2 friction reducer. I am happy to say that the sound has quietened up a bit and it feels smoother. It also makes the vehicle feel less "draggy" like when taking your foot off the gas pedal, the vehicle slows itself down more than usual- this seemed to fix that issue as well. So before you get into wheel bearings and all this other stuff, simply try to top-off your differential fluid with this and see how it does first before going "down the rabbit hole".
