1979 Ford F250 Dana 60 rear question - Pirate4x4.Com : 4x4 and Off-Road Forum

NOTPRETTY · 12-07-2004, 07:17 PM

Are they all 35 spline? And what is fair market value for one assuming good condition and open with 3.54 gears? 100? 200?

muddinmike · 12-07-2004, 07:46 PM

the one I had was 35 spline

they kinda suck so maybe 100 thats what I paid for mine but I would never buy another

In my Dana books it doesn't list a 35 FF for 79, but that is from memory.

One way to find out...

Davethorik · 12-07-2004, 08:44 PM

they shouldn't be 35 spline. most likely 30 spline. but yeah, pull a shaft and check it out.

muddinmike · 12-07-2004, 09:18 PM

doh daves right, I remeber now looking at the 35 spline spools and axle upgrade but went 14 bolt instead

NOTPRETTY · 12-07-2004, 09:44 PM

MuddinMike...Why do they suck?

Jrod-13 · 12-07-2004, 11:12 PM

well, they take alot of money to bring them up to the specs of a 14 bolt, 10.25, or dana 70.
as for price, I wouldn't pay more than $50-100 for any rearend, especialy a rear 60

muddinmike · 12-07-2004, 11:14 PM

Just weak over all compared to a 14B

NOTPRETTY · 12-08-2004, 10:03 AM

What size are the shafts in a 14 bolt...not spline, but diameter?

I always considered the 14bolt to be in the same strength class as the Dana 60. What specific components are stronger?

everything.

the shaft size is 1.5" just like a 10.25, and 70

NOTPRETTY · 12-08-2004, 11:53 AM

A 35 spline ford f250 1979 diff has 1.5" shafts too. Anything else? I do believe the F250 1979 dana 60 is pretty good. Single wheel...etc I could be wrong though.

Also, I thought that most Corp 14 were 30 spline...yes some were 35, but most 30?

78Buford · 12-08-2004, 12:10 PM

All 14 bolts to my knowledge are 30 spline.

Nearly all Ford rear D60's have 1.31" axle shafts, and are 30 spline. I had an older 16 spline pair of axles in the one I used to run...before upgrading to a 70.

The D70, Sterling 10.25", and the 14 Bolt are all in the same ballpark in regards to strength. These are all true "One ton rear ends."

To keep it simple, think of a D60 as a 3/4 ton rear axle. Yes, some Dodge's used 60's in the rear of one ton trucks, but they simply aren't as beefy as the 70, 14B, and 10.25".

35 spline Dana 60's (with 1.5" axle shafts) do exist but the vast majority of 60's were 30 spline.

This is taken from the 14 bolt tech article.

Quote:

Dimensions on the shafts are:

Spline Diameter (yellow arrow) 1.59"

"Neckdown" (green arrow) 1.367"

Operating diameter (purple arrow) 1.351"

Spline length (blue arrow) 2.165"

Spline engagement (red arrow) short side 1.418"

Spline engagement (red arrow) long side 1.569"

NOTPRETTY · 12-08-2004, 01:55 PM

Okay...Can anyone confirm that a 78-79 F250 Dana 60 rear axle has 1.5" diameter shafts? Come on....Some has to know. I thought they were all 35 spline, but could be wrong.

CumminsZuk · 12-08-2004, 02:12 PM

ive got both and the 14 bolt shafts are bigger and the spline count on both are 30 spline... only things that i think are better about the dana 60 is ground clearance and weight.. just my .02

I thought I already answered this...the axle you speak of has 1.31" 30 spline axle shafts. The 14 bolt has 1.5" 30 spline shafts. The D70 and Sterling have 1.5" 35 spline shafts. I believe the only 35 spline D60 rearends came under some Chevy cutaway box vans.

BUZZISCRAZY2 · 12-09-2004, 02:49 AM

Hmmm.......dana rear 60's not tuff ? I'm running 700 HP w/60's and NEVER broke a drivetrain part..........yet the same motor in another f-350 I have with a 60/70 combo broke constantly for 5 years...........how the piece flexes makes all the diffrence in the world.

1 is a 4 link truck, the other is leaf sprung........

And Iam prolly the most brutal mo fo you have ever seen behind a wheel........

14 bolt shafts neck down.

Tippy · 12-09-2004, 07:38 AM

According to ARB's list of applications, some 30/3500 series chevy's (1975-86) and some ford 350's both e and f (1988 on) had 35 spline 1.5" diameter shafts. All others, including 1975-'84 f250's had only 30 spline.

Davethorik · 12-09-2004, 12:01 PM

yeah, the axle under the chevy you mention is a D70HD found in dually pickups, it has 1.5" 35 spline shafts. I am confused on the Fords listing, because some of the F250's came with D70s that would also be 35 spline. I am guessing ARB just doesn't have their shit down.

Yup, Tons of people snap Stock 30 spline 60 rear shafts like toothpicks

Toddy · 12-09-2004, 12:26 PM

Some 60 rears came with 35 slpine axles. And if not you can put 35 slpine D70 axles in a 60 with some work. Some 60s had the bigger spindles so the 35 slpline shafts would fit but if not you can bore them so they will fit and get a 35 spline locker and you have the clearance og a 60 adn the shaft strength of a 70 or 14B.

not all 70's have 35 spline shafts, i have one that has 23 spline shafts.

Davethorik · 12-09-2004, 05:59 PM

Since this clusterfuck of a thread is about 35 spline dana 60s, i figured I wouldnt need to mention a 23 spline '70.

NOTPRETTY · 12-11-2004, 10:07 AM

I agree...anyone reading this thread would leave way more confused. Fact is...I don't think anyone here has a clue. I sure wouldn't trust anyone and go buy something.

Nuts and bolts:
What vehicles could you get a Dana 60 35 spline rear axle in? I am talking about FORD, CHEVY, DODGE...whatever. Year make and model.
