There is a spring retainer shown for most F250's, and other models (C4TZ-1A055-A), but not for one particular 1978 F250 4WD model, and no 1979 F250/F350 4WD's.

I have three separate 1973/79 Ford Light Truck Parts Catalogs on microfiche: first printing of 1979, 1981, and the last printing of 10/88.

None show that retainer for an F350. It must have something to do with the hub (D8TZ-1104-E), which only fits the two models.

 

Have you checked the Dana web site ?

 

Dennis, use your parts catalog, go to text section 30, page 6 in the front axle parts list applications...see what parts lists are shown there for 1979 F350 4WD's.
Now go to the parts lists themselves.

30.5AA is in section 30.5, page 24, the other three are in section 30.5, page 12.

Read down the columns....whadda you see for basic part number 1A055 under those appropriate parts lists?

I see nothing!

Post this illustration: Section 30 / page 17..1976/79 F250 4WD & 1979 F350 4WD = the entire front axle assembly is shown.

With regards to the chart the axle codings for 79 f250/350 are:
S
AA
R
Z

Read down the columns....whadda you see for basic part number 1A055 under those appropriate parts lists?

Nothing for application AA

My guess is that axle is a Dana 61.


I didn't notice you posting a BOM number from that axle.

 

In post #5 I listed the tag said 61. I was always told that it was a Dana 60 and they were labeled 61's because they were the front axle version. I am assuming this is incorrect. I am learning more every day from this sight. Thank you to everyone.

I attempted read the tag and this is as close as I can get:
4:10 D9?A?A6D
610023-?

The question marks are either elegible or missing a character.
Does this help?

 

As you can see below ...my book doesn't show that application in the chart.

Perhaps Bill's newer edition does ?

 

You may be reading too far into this. The 80's model trucks with Dana 50s and 60's used a Warn design locking hub that did not use an external spring. 78-79 Dana 60's used a Spicer locking hub which used the spring. The wheel hubs don't make a difference as the aftermarket locking hubs will fit either way.

FYI, the Dana 61 is merely a rear application Dana 60 with a specific housing and carrier to run tall, fuel economy gearing (3.08's). There are no D61's used in a Ford front end.

There no suffix of A6D listed in the parts catalog.

It's prolly this: Ford # D9TA-ACD / Dana # 610023-6 / Dana 60 / 4.10-1 / Free Running Hubs / non Limited Slip / 4500 lb. Front Axle Capacity / > > Parts List # 30.5AA < <

 

Since the hub only fits one 1978 F250 application & 1979 F250/350's, and there no spring retainer shown, the hub prolly has a design change inside that allows for the retainer to be eliminated.

But...I'd be the first to admit that I'm not that familiar with 4WD's because I worked in Los Angeles for 35 years, and unlike today, there weren't too many of these 4WD trucks around in the LA area back then.

The last time it snowed in LA LA Land was 1949.

Ppl back then didn't buy these trucks as everyday daily drivers. Around here today, they're everywhere.

 

Well, if you look at the aftermarket, the hubs never changed between 78-79.
I've parted a few 60's from both years and they've always had the spring retainer with factory hubs.

I've never worked in Ford parts, but I have worked Toyota and Chrysler parts. So I know how numerous updates and supercessions can lead back to one part number to cover multiple superceded ones. It is confusing to say the least.

Okay, So there may be a need for the retainer but there is no part number to search for. I seem to always have the odd parts and pieces. I will probably have to buy new Warn hubs. I might try to look at a newer model and see if they will work. Thank you guys for all of the help with this.

 

Using 30 yr old part numbers can be a real pain, but this appears to be easier than this whole thing has played out.
The dana 60 axle was used by all of the big three, and all of these parts are almost a direct replacement. The exception would be the spindle length, and stub shaft length, but for this purpose, pretty much identical.
Since you have one locking hub assembly that is good, why not take it apart, clean it up, and use it to identify the missing components? You can then, with parts in hand run down to the nearst dealership. I would actually run down to the chevy dealership, since these 60 axles were available for a longer period than the ford or dodge.
With the correct parts in hand, you can easily match up the identical components.
This should be a very easy fix.

If not, are these original Spicer units?????????
If Yes, care to sell them, even if one is incomplete????? Could help offset the cost of brand new Warns..... Pm me if interested please.
