What gear oil do you run in your rear differential? I know the owners manual says 75w140, but I think now we're supposed to run 80w90.
Looking on Rock Auto, the Motorcraft 80w90 shows Premium Rear Axle Lubricant. The Motorcraft 75W140 shows Synthetic.
I think we supposed to use full Synthetic?
Rock Auto has a Mobil 1 75w90 that is Synthetic.

you have that backwards, the 80W90 call was superseded by 75W140
run a 75w140 synthetic that has limited slip additives (most should)

Ahhh. Thanks for the help.

Holy crap it's expensive. Rock Auto has it at $22.89 per quart, whereas 80W90 is only $7.59 per quart.

Use 75W140 synthetic, Using synthetic negates the need for friction modifier.

2.5 quarts, although 2 quarts is usually enough if you're not pulling the axles and getting ALL of the fluid out
don't know, ask Ford
