i am upgrading the axles in my 78 f-150. converted the front Dana 44 to a 3/4 ton using chevy k20 knuckles/spindles/hubs. i just got a Dana 60 for the rear and i don't know if i need to change the ring and pinion.

so my question is, what were the options for gearing on my truck? it is a 78 F150 Ranger 4x4 styleside, 400 c-6, 9 inch rear. the door jamb stickers have been painted over

my vin number is F14SEBG1005

there is a small tab with numbers on it that is bolted onto the front axle. are these helpful?

if all else fails i'll have to take the cover off the front axle and see if i can count the teeth

 

Yes.. it'll likely have a Bill of Material (BOM) number which you can decode using Dana-Spicer's reference manual. The link is in the tech thread hyperlink sticky.

The BOM is also stamped on one of the axle tubes...

 

Dana 60 may have a plate with 7 or 8 digit Dana ID number (examples: 603010-1 or 603010-11) bolted (2 bolts) to housing adjacent to inspection cover.

The Dana ID number may be stamped on the axle tube. If number has 7 or 8 digits, post what it is.

Ford ID tag located under one of the bolts that retains inspection cover to housing. Many of these tags missing today.

 

I had taken the tag off last time I changed the gear oil because it twisted when I tightened the bolts. I kept it, in a safe place that I don't remember.

Ill look for some numbers on the tube. If I still can't find anything ill just take the cover off again.

 

AXLE code stamped on the 2nd line-far right of the metal Warranty Plate, located on the left door face below the latch.

Glued to B pillar Safety Standards Certification Label that's been painted over does not have the axle code printed on it.

VIN does not contain trans or axle codes.
