OK, I have no less than 7 Dana axles right now.

ZJ D35
XJ D35
XJ D44
XJ D30
Ford RC D44
Ford FF60
Unknown D70

Now, what I'm really trying to do is ID the origin of the D70 (I made a seperate post on this)...but NOT ONE of my axles has the BOM stamped in the tube like any manual shows????????

Is this BOM a U.S. thing only? I never have seen one

My oddball d44 rear had the number stamped in the normal spot, on the right side tube (when looking at the axle from the extreme rear of the vehicle), but the BOM number was buried in a longer alphanumeric string.

Mine read:

DR606646 C78

... with "606646" being the actual BOM number.

cm "anything like that on yours?" k

Nuttin.

No numbers, no letters, nuttin at all.

That's what's got me stumped.

Maybe the damn things are only lightly scratched on and are rusted away after one cdn winter???

There are definitely some oddball Dana axles out there with wierd BOM #s. About a year ago my friend picked up some axles that still have us stumped. I've run every number I could pull off the axle and have gotten nothing. I've even tried to do what cmk did, and it still didn't work.

Here is a short description of the axles. There are three of them, two steering and one non-steering. They all appear to be RC D60s, with disc brakes, 8 lug, king pins, some sort of traction aid, and 4.10 gearing. All axles are offset to the driver side. All three axles were also set up for coil springs and some wierd looking radius arms.

Supposedly these axles came from some sort of 6x6 vehicle. My friend also has the t-cases from this vehicle. There are two rockwell t-cases attached with a long tube-like adapter. Apparently this all hooks up to a ford C6 auto tranny. Even the driveshafts are wierd, as they have CV joints at each end.

They are only lightly stamped on, but U can find them if U use enough rust penetrator.

Patooyee,

Das whats got me stumped.

There deifnately never where any numbers there of any kind, ever. I have cleaned many to find nothing.

Unless they just drew it on in pencil, there's gotta be another explanation?

C'mon Canucks...what's your story?

I've checked out the BOMs on a couple of axles I've got.

One GM D60 housing and one Ford RC D60. They were both stamped on the axle tube. The GM one was actually double stamped (one over top of the other stamp and slightly overlapping). That one was tough to read.

GM used BOMs in B.C.... :D

Where there any tags on the rear cover? Some Dana axles that were built for Chrysler did not have the BOM stamped in the tube, they just tagged them. If it has a tag, it may only have the last four numbers of the BOM so you will need to add 60 to to make it complete.

OK, so how many digits in your BOMs?

Might be it was on a tag, and the tag has gone?

Or maybe I can add / subtract digits from the numbers cast in the web to get a BOM

I've also checked for bom's and can't find any but with the corrosion on them I just figured they have rusted over. I've given up finding any on my 44's since I blasted them. but I ve looked on other 60's and couldn't find anything on them either

They are stamped so lightly that sand blasting would DEFINATELY erase them. I have personally seen axles with TONS of rust, and after scrubbing enough with penetrator and a cotton rag, was able to tell the BOM though.

Mine is not stamped with the BOM, it has a sticker.

I hope no one's going to take a shit all over me for resurecting this thread, but I think I have an answer for Bill (if he hasn't already found it) and a BOM question for those of you with better resources than I.

I've got a Ford RC D44 from a Canadian 1977 F150 that appeared to be in good shape (thanks to a leaky Ford engine that liberally coated most of the front housing with a thick layer of oil probably before it's first winter), but I could not find a BOM anywhere even after liberal soaking and scrubing. I gave the SOB a light sandblasting tonight and low and behold there was the BOM as clear as can be stamped in the front of the passenger side tube.

Now if anyone can tell me what it means I'd appreciate it.

8236B4 603808 5

None of those numbers come up on the Dana site - prob too old.

maybe check Mr N's Dana 44 page?

I believe your BOM is 603808-5

Yeh, I checked the Dana site before posting, but they seem to only have info on 1978 & up. I guess I was hoping someone would have access to another source.

The tag off the 9" rear from the same truck had the following info on it if it's of any help...

WFE-V2 6KC
*L11 9 393A

The number represented by the asterix has been destroyed, but I'm pretty sure it was a 4 as in 4.11 gears.

Bill you said they might be Mil axles, would Dana stamp Mil stuff?
whats the story on Mil 70's?

I have several axles right now and I have the same problem. The RC60 that I have took a sandblasting to find to BOM. The salt out in your neck of the woods is BRUTAL so I would imagine that is the problem.

I have the dana 1960-78 book at home and I might be able to help. I will check in the morning.

Listed as a 1976-1/2 F-150(not F-100) D-44. 4.09:1 open diffs. Hi-pinion, disc brakes.

Nothing special that you don't already know as it is in the origanal rig.

The 'L' in the '4L11' of the ID tag denotes it is a limited slip rear 9".

Actually I stripped the axles out of a rusted out Ford. I had it narrowed down to either a '76 or '77 but did not know which, so that does give me something I didn't know. Thanks for the info.
