Im running 75w-90 for break in of my hp30 and D44.
I am going to change the fluid after 500-1000mi. Im wondering if it will be safe to run 75w-140 synthetic f/r to quiet down the lockers and to help when i am hammering down on the axles. mpg is no concern
front lockright, rear full detroit, 4.56 gears
