What weight gear oil for the rear diff?

[Banjer Picker]

Whats the recomended weight gear oil for the rear diff. It's just a standard open carrier. The Bronco sees about half n half street/off road but it's hot @ss Texas.

I use 80-90w gear oil in all boxes

Just about any weight you want I like to use the 80-140W myself semi synthectic as well. but when i cant get that then I just use standard 90W

Thats what I was thinking, it just seemed really thin tonight when i cut the bottle open. Maybe its the 95 degress at 11 pm at night thats doing it.

Thanks guys!
