Drove it yesterday for 16 miles at speeds of 40-50mph, shot it with a temp gun when i stopped and it was at 117 degrees, so it seems the 75W90 is working well

x2. Also, does switching to a thicker gear oil in a high mileage differential make sense as far as added protection?
Yes, based upon what Pablo has stated more than once in the forums. I have used both 75W-90 and 75W-110 and I saw nothing detrimental from using the 75W-110 and if it provides more protection than 75W-90 then all the better (which I am confident it does). It is the same price as 75W-90 and I would use 75W-110 in any axle that calls for 75W-90 (new or old).
