dana 44

[BRUTUS_T_HOG]

will a dana 44 from a 72 directly replace the 44 i have in my 69? just found one for $100, this would save me several hundred dollars

it will bolt in, the gear ratio might be different then there are low pinion and high pinion the drive shafts are different lengths. If you do swap low pinion for low pinion or vise verse no problem.

[BRUTUS_T_HOG]

ok its a low pinion just like i have. he said the ratio was 4.09, i don't exactly know how he got this information he said the ID tag was missing and mentioned counting the gear teeth, so he might have done the math and came up with 4.09 but dana just rounds up to 4.10? i have 4.10's i believe, its been a while since i looked

[fordman]

4.09 4.10 is close enough to use together.

[BRUTUS_T_HOG]

yeah since i never use 4wd on a solid surface that 2wd can handle. would it come from the factory as a 4.09 up front and 4.10 rear?

[BRUTUS_T_HOG]

ok so he got me a picture of the ID tag. it clearly says 4.09 with an axle code of d31a-ga. bill of material code 603395-1. i looked it up and it appears to be from a 1973-1975 f-250.

will this still work?

[Doug Comer]

It should, I'm sure someone will have a more definate answer for you.

Brutus,

It is from an F250. Do you have an F250.

If the anwser is yes, then yes it will work, if no, then it will not.

you will have to make some changes regarding the brake hoses.

[averagef250]

Yes, our trucks were 4.09 front, 4.10 rear. Unless you had an old low pinion 60 front then you got 4.10/4.10.

[BRUTUS_T_HOG]

ok i verified my current ratio is 4.09, i just want to be sure this axle will fit perfectly when i drive 5hrs round trip to go get it. if there is no difference then why would the BOM code say its from a 73-75 and not a 67-75? there must be some kind of difference

[averagef250]

Yeah, the difference is the YEAR IT WAS MADE!!!!! They are all the same.

[BRUTUS_T_HOG]

ok thanks guys. i was just trying to be sure. i just noticed you are from portlandish.. which is exactly where im heading to go pick up this axle. funny

[71PA_Highboy]

I still haven't understood if you have an F100 or F250.

[BRUTUS_T_HOG]

i guess i never mentioned that, i have an F250. i already picked the axle up.
