If my memory serves me correctly 4.56 is the lowest so far. Happy swapping.
And that a 10.5 is metric isnt it? Or is that a typo and you meant 10.25? In that case I have 5.13 gears in mine...so there are lower gears...

So you picked up a rear Dana 60 with 16 splines. Most likely it was from a 70-75 Parcel Deliver van or a 73-75 F250 Camper Special or a 70-75 HD 4x2 Pick-up. It came with the same length axle shaft on both sides, Spicer part number 35445-2 with 16 Splines and 34.56” long.

You want to swap the 16 spline shafts for 30…

Below is the Spicer axle shaft part number that is the same length axle shaft but with 30 splines! (Hint don’t for get the spider gears when you pull the shafts, or if your really luckily you’ll find a No-Spin)

35467-3 30 Splines 34.56” Dana 60’s
1976-1979 F250 Crew Cab – Full float
1976 F250 ¾ Ton 4x2 Pickup – Full float
1975-78.5 F250 ¾ Ton HD 4x2 Pickup – Full float (Lots of BOM’s)
1975-78 F250 ¾ Ton Camper Special Pickup – Full float
1979 F250 4x4 – Full float
1979 F250 4x2 – Full float

35467-3 30 Splines 34.56” Dana 61’s
1974-1977 F250 ¾ Ton HD 4x2 Pickup – Full float
1979 F250 Crew Cab – Full float
1979 F250 4x2 – Full float

Not a good option, might work as the shaft is similar in length.
31494-1 30 Splines, 34.75”
1969-1972 C20 Truck Chassis w/Leaf Springs
1969-1972 C20 Truck Chassis w/Coil Springs
1968-1972 C25 Truck Chassis w/Standard Wheel base
1967 L1500 Station Wagon (Chevy)
1967 K1500 Pick-up
1968-1972 K25 Truck Chassis

NOTE: I’ve never done this swap, just looked up the info for renopowers.

I cannot remember where I saw the information but I believe I saw that the 16 spline and the 30 were the same size around (1 5/16"). So if they are the same size what benefits do I get from the 30 spline? Is it just aftermarket availability or is there a strength difference?
If there is a strength advantage provided by the 30 spline can you explain how that works?

Thanks!

basically, more surface area. the finer the splines, the more material that is in contact between the axle shaft and carrier.

Its also important how the splines were made which will apply to aftermarket/custom axles more so than oem shafts.

Hope this is the right place, what gear oil should I use for my stock 86 FSB 4x4 front & rear Dif. I couldn't find it in my Haynes. I looked at the Autozone, 90wt or 145wt. Does my 86 have limited slip?

Thanks

1990 Bronco and F150, F250, F350 and F-Super Duty rear axle codes codes that will be on the door decal under Axle. open diff unless specified with weight rating in parentheses. If there is a 3rd digit which is a 2, the front is limited slip. Source is 1990 Ford Specification Book Truck volume 2.

Code - Ratio (weight rating)
18 - 3.08 (3800)
19 - 3.55 (3800)
H5 - 4.10 with limited slip diff (3800)
H8 - 3.08 with limited slip diff (3800)
25 - 4.10 (3800)
27 - 3.73 (5300) Note: no 4x4 has a 3.73 ratio
29 - 3.55 (5300)
B9 - 3.55 limited slip diff (5300)
35 - 4.10 (6250)
39 - 3.55 (6250)
C5 - 4.10 with limited slip diff (6250)
C9 - 3.55 with limited slip diff (6250)
45 - 4.10 (7400)
49 - 3.55 (7400)
D5 - 4.10 with limited slip (7400)
65 - 4.10 (8250)
69 - 3.55 (8250)
F5 - 4.10 with limited slip (8250)
72 - 4.63 (11,000)
73 - 5.13 (11,000)

This will hold true for 1990 and maybe 1987,1988, 1989 and 1991. 90 is the first year I have specs on F-SuperDuty.
3800 rated axle fis Ford 8.8
5300 rated axle was semifloat sterling
6250 rated axle was full float sterling 10.25 found in F250-HD and F350 with single rear wheel
7400 and 8250 were dual rear wheel full float found in F350 and F350 chasis cab
11000 was a dual rear wheel Dana 80 found in the F-Super Duty.

Edit: This does not include E-series vehicles. Also, prior to '87 the weight rating can't be used to determine the axle in F-250 and larger trucks because there were both Ford and Dana axles in use.

This info is from official ford spec books and is therefore suspect. There were a lot of wierd ratios used in some of the Dana 60 and 61 2wd F and E series, for example 3.33, 3.25, 3.47, 2.73, 4.0, 2.75

B7- in 1984 this code was used on a 4050 rated axle with a 4.10 ratio limited slip. In 1986 is was used for Ford semiFloat Sterling with a 3.73 ratio limited slip diff (5300 rating).

Dana 61 codes (some of these need to be verified)

31- 3.07 ratio in 1983-85 (6250 rating) and 1983-86 with a (6340 rating)
32- 4.10 ratio in 1983 to 1986 with both a 6250 and 6340 pound rating

I see an omission in your 81-86 axle list. There were a couple versions of the Dana 70-1U available those years (I've found several of them and have one in my rig.) I believe they would have had 3.73 and 4.10 gear ratios. I wonder if it may fall into those mystery numbers?

The 81-86 is incomplete because that is all that I have notes or information From the appendix of the 1987 Ford Light Trucks Fact Book. There are a couple of pages in the back on Past Model Identifcation for axles sued from 1981-86. Do you have the axle code and year from the door decal? The "mystery" codes 26, B6 and B7 are only a 4040 pound rated axle so there is no way it is a d70 of any type.

Edit: Look again and see if the codes have been added.

Time to beef up the rear end here... and I now have my choice between a sterling 10.25 and a chevy 14 bolt. We picked them both up for little, and nothing. So if you had the choice which would you use? I will have to replace what I have in there now. 5.13's and ARB, and of we'd do a disc brake conversion while we were at it.

thanks

you dont need the vss, and 14b is cheaper to build, so i would do the 14b. then sell the sterling to someone here who needs vss, and you can pay for your gears or something.

I'd probably go with the 14 bolt too, unless you want an ARB, I seem to remember hearing ones not available for the 14 bolt? I really don't know, check for yourself nbefore you do anything.

If it were me I would take whatever axle I could get an ARB in

I believe that there are now ARB's available for the 14 bolt. I read that somewhere, but I'll check on it

Let me try to get something straight... when looking for a 14B... it will be just that, 14 bolts on the diff cover, right? Also, what's the quickest way to find out whether it is full-float or semi-float?
Thanks.

You no longer have a tone ring in your diff which means you lost your VSS. There are some kits that you can get to add one to your t-case output. Do a search and you will find some threads. Another way is to adapt a D60 to vss or go with a Sterling that had vss from the factory.
