What gear oil in front diff?

Hey, I was wondering if anyone could tell me what weight oil to use in front diff? I know that the rear takes 75-140 syn, but not sure about the front.

Thanks, Scott

I actually just e-mailed guzzle the other day to ask him this same question, and he said ford is now suggesting the same 75-W140 for the front and back.

TYZ, thanks my 2003 manual says that the rear takes 75-140 but dose'nt say what the front is. I kinda thought it was the same but wasn't sure. Getting ready to put 4.88 gears in. And was trying to get everything I needed.

Thanks again

What engine do you have? I was thinking 4:56 or 4:88 when I lift it with 35's. I only have the 5.4 in mine, so I might need 4:88.

i did a 6 inch lift with 35s the 6.0 pulls 4.30 gears perfect. It drives like when it was stock with the 3.73s. I ran mobil 1 75-140 synthetic.

I have the 6.8 in mine with 37's, and 3.73 gears until next weekend then 4.88's.
