I believe axle code " 39 " in a 1989 Ford F-250 is a :
( conventional / non limited slip with 3.55 gears )

3.73 conventional axle ( non - limited slip )

I was looking at the 1997 Ford F-250 Heavy Duty owners manual and there is a " C 5 " axle code listed 4.10 ratio - limited slip manufacturer - Ford capacity - 6,250 pounds
On a 2003 Ford Explorer : Open the drivers door and there is an information sticker on the latch pillar You will find the axle code under " axle " Once you have the axle code you can determine the axle ratio
According to the ( 1996 ) Ford Bronco Owner Guide : Axle code ( 19 ) is a Ford conventional ( non Ford Traction Lok / limited slip ) axle with a 3.55 ratio
