hey guys, looking for some help fing out what model my rear axle is. I have a 1977 f250 hiboy built 1/77 6.6L c-6 full time four wheel drive. The rear axle tag rotted off my cover. I tried to gently clean the housing for the other codes. The rust got the best of it. I pulled the cover off and have the numbers off the ring gear: 10 22 76 DANA 30363 b3r45x 41 10. On the inside of the case is: 2 60 hd. The door tag is blank for axle code but the rear axle rating is :3950. The other night i found a link for a site from dana. I should have booked mark it because i can not find it today.
thank you,
ken

Every F250 sold in the 1970's had a rear axle capacity of 5300 lbs., 4 WD or 2WD. There's no listing in the Ford parts catalog for 3950 lbs for any F250. Two rear axles were used in 1977 F250's, Dana 61-1 or Dana 60. None of the above numbers can be translated by using the parts catalog. This I know: 41 10 is 4.09; or 4.10; or 4,11-1. Look on the axle tubing for a stamped Dana ID number, it's 6 numbers with/without a letter suffix. The original axle tag was rectangular in shape, on the left side of the housing adjacent to the cover, and held on by two bolts.

Number would be difficult to be missing, the Dana ID number is stamped into the axle tube (parts catalog doesn't say where). Look again on the door tag, Ford didn't always stamp the codes where they are supposed to be. The axle codes is three digits, the tranny one. They may all be stamped together. If the rear axle on your F250 4x4 is the original, it will be a Dana 60. It's also possible the door has been changed, but the original VIN wasn't swapped over. A 3900 rear axle capacity is F150 or E150 territory, not an F250. 3900lbs would be (in your case) a Dana 44. Dana 44 has a 10 bolt rear cover, a Dana 60 has a 9 bolt rear cover. What are the first three digits of the door tag VIN?

So it is a 60 rear bill? It is weird that the door says 3950 for the rear rating. The truck was for a fire dept most of it's life so over all it's in pretty good shape for upper ny. the box was repaired poorly but picke up a nice one from jersey that needs minimal work. I can not wait to get a locker in the rear. I shouldn't have to be as hard on it pulling fire wood out of the hills. I am going back to my garage to check the numbers again. Thank you for your guys help.

Dana 60 it is...or at least that's what the door tag axle code is. What's in there now? Prolly a Dana 60, but I'd still look for the stamp number...Mil1ion posted a pic showing where it is.
Fire Dept? Well heck, that explains it..all FD vehicles were special ordered as a general rule. Look on the VIN plate again, see where it says DSO? What are the numbers?
I asked for the VIN first 3 digits to see if the three number pertained to a F250 4X4, and they do. I also asked the question to see if door tag was the correct one. The F26 is correct. The actual VIN (Vehicle ID Number) doesn't have axle or trans codes, but the Rating or Warranty (VIN) Plate does, because that's where the codes are.
Dennis, I know what VIN's pertain to, after 35 years behind a Ford Parts counter, I'd better.
