Hello Folks,

On my F100, I have a Dana 44 and the shafts have some axial play.
Does some of you know what is the "acceptable" value?

I plan to change the bearings but as I am in France I cannot rely on the local axle shop, so I would be sure to order the right reference for my truck.

I didn't found out if there is some Ford specificities on those D44?

I seems that all older D44 are similar, does jeep CJ bearings would fit?

Is it necessary to change the retaining plates?

I'll be doing it the DIY way, so I'll need bearing retainer as well I guess...

An one last technical question, what does maintain the preload in the bearing? the contact of the retainer plate?

Thanks for your help!

 

1959/67 F100: When Limited Slip was ordered, Ford usually installed Dana 44's as the 9" with Limited Slip wasn't available in F100's until 1968.

But there are two other possible Dana's: Dana 60.2 (1963/66) and Dana 60.3 (1966/67), both have Limited Slip.

Was your truck sold new in the US or Canada?

If so, the Warranty Plate is riveted to the left door face below the latch. The AXLE code is stamped on the 2nd line-far right. Post what it is.

The axle bearings are the same Dana 44, Dana 60.3, Ford 9 inch, but the Dana 44 uses different axle seals than the 9 inch. And there are two per side, while the 9 only has one.

See parts catalog pic: Axle bearing is 1225, lock ring (usually come with the bearing) is 1180. Specific Dana 44 axle seals are 1177 and 1181. Retaining plates are 4020.

These are the basic part numbers only. Once it's determined whether you have a Dana 44 or a Dana 60.3, I'll list the complete part numbers, sources in the US that have them.

 

Thank you so much for your answer.
As far as I can decode, the truck was assembled in California and sold in Seattle district.
With axle code A8 that is supposed to be dana 44 with locking that is what I actually have on it.


Thanks again for the support

A8 = Dana 44 or Dana 44.3. Same axle bearing for both (same as 9"), but the seals are different.

Will get back to you later, as it's dinner time here in LA LA Land.

 

Unfortunately, I'm not home to check if I still have ID tag but I have an old picture...
Can the small rectangle that looks attached to the right bottom bolt be the the tag?
In that case, I can send somebody to check...

 

The long rear axle ID tag is located (under two bolts) on the left side of the inspection cover in this pic, exactly where the parts catalogs says it should be.

Such great documented answers all the time, thanks!

I've just remember that there's nobody home those days to check, so I think I'll just order the bearings and the 2 types of seals...

 

Hello,
Just came back home and get to read the tag, it says:

C7TA-K
602909-4
3.54

So I've found that's a Dana 44-3.
Looking at the vents, it seems that there is no internal seal and that the bearings are lubricated by the diff oil.
So I think I can manage with jeep parts that have the external seal and the bearing in common.
The retainer may be different, but as there is no interference with the seal, should be ok...

Let me know what do you think about it?
Thanks

As I solved my problem, I thought I would share the outcomes.
1st of all thanks you again Bill for the support.
As as you may know I'm living far away from my truck I had to do some research before being back home to be ready to fix the issue.
After some research I understood that the dana 44 has similar set-up to mopar rear ends thus was afraid that he thrust pins were missing in my differential as the en play was quite big.
So I started to gather all the parts I potentially need thrust pin and shim...
Then to make the story short has to go back home and work on the truck before receiving all the parts...
I've been quite lucky the nothing was actually missing and been able to fix my issue by just removing some of the shims behind the backing plate.
