Diff/Axle Identification

Hello everyone,

I recently bought a 59 f-100(per VIN), and I am trying to everything that I can before I tear into it. Someone put 3/4 ton axles under it, and I want to know if possible what year of a truck that it came from. On the upper right side of the rear diff.: C30255
lower right: 60 (I think, perhaps Dana 60). On the upper left side: 1968 618. Lower left side: 2018 188. Finally, stamped on the right side of the axle 124 9B 2196. If someone out there can tell me what all of these numbers mean I would greatly appreciate it.

Here's some info from my web page describing my 1956 F-250 real axle:

... supposedly came with a Dana (Spicer) 60 rear end from the factory. I checked the gear ratio and it matches the rating plate, 4.56:1 with 41 ring gear teeth and 9 shaft teeth (41/9 = 4.56). There is a tag on the axle with the markings 41/9 which also matches. I checked out the patent numbers cast on the axle (1968618 and 2018188) and found several references to these numbers for the Dana 60 axle. Finally, there is a 60 cast in the lower right rear corner of the gear housing which is also referenced in several notations for the Dana 60 axle. ...


There are several markings on mine that match yours. I'd say it's a pretty fair bet you have a Dana 60 rear axle. If you can find a tag on one of the bolts that has the ring and pinion gear tooth count we can be more certain. I don't know if it is possible to narrow it down to the exact year but that's probably not too important since the parts from different years should be interchangable.

As far as the front end goes, I can't say for certain in 1959 but in 1956 the front axle and steering were the same on the F-100 and F-250 so I'm not sure what it would mean to put a 3/4 ton axle in the front. Maybe a 4x4 setup?

George,


Thanks for the information! It is a 4 wheel drive. I believe that the front end is a Dana 44. On the diff the numbers 44 4F are stamped on the lower left side. Is the 44 4F the Dana/Spicer heavy duty diff?
