Is it possible/ will it weaken the Dana 60 to put 1/2" studs in instead of the 9/16"? That way I'm not drilling out anything?
I'm also curious if I have the heavy duty front axle should I not have 9/16" studs? Do bigger studs directly relate to strength of axle? Sorry for the barrage of questions, I've never had to deal with wheel studs before
@Numberdummy got any input on what axles/studs I should have or what I can do with my current set up?

@NumberDummy or @mikeo0o0o0 can you help me sort this out. I’m beyond confused!
See post 16.
btw: E1TA-BZB is from a 1981. I'll have to look and see if it's different.

Oops, I corrected my previous post mentioning the "D1" instead of the "E1" that you showed on your axle tag.
But like ND said, that's still an '81 truck part. And isn't the rear axle the one with the larger studs anyway? That would explain why they're not a match to the front axle, assuming the front one is not also swapped in that is.
Any info on the "24 P" code in his truck Bill?
And what about those E1TA numbers? Would they have changed every year, or could an axle have carried the same number over several years still? Meaning the axle could have come out of, for example an '84 truck instead of only an '81?
Just curious. Thanks

So @NumberDummy my confusion is my axle tag on the door plate is 24P . That says I should have 4.10s Dana60/61 rear and a Dana60F with 4.55s. My truck has under it a Dana44 see pic where the pumpkin says 446C <- thats the front axle and the rear axle is the 605022-1 3.73 E1TA Dana 61.
What does my axle tag actually decode to (ie What axles SHOULD my 74 F250 have under it) and if I am correct, why are my gear ratios different?

So crap someone HAS been swapping axles on me. I don't know why you'd DD a truck with Dana60 front and rear and swap it out for this crap.

1973/75 F250 24P: 24 = Dana 60 Rear Axle 4.10-1 // P = Dana 44-6CF 4.09-1 Front Driving Axle.
Parts catalog sez 4.55 which is an error.

So I guess in summary. My front axle is still original. My rear axle has been swapped out for an 80s Dana61 which still doesn't explain why I had the 9/16" wheel stud. And the catalog was a misprint. So I should've had 4.10 and 4.09 gears.
Thanks again Numberdummy, sometimes I can't believe the knowledge you've gotten stored in your noggin. I'm sure you've forgotten more than I will ever know on these trucks lol
Edit* fixed my comment about wheel studs to reflect NDs info from earlier (it slipped my mind) and he mentions it again further down.

Distracting: While you sit back home in Indiana, I've got one eye on the computer, the other on the TV .. watching the fire news.
We've got a HUGE brush fire burning here, the other night when the winds died down, a bit of it began burning north to within a mile of my house.
The fire dep't knocked it down using ground personnel, but to the south, it has burned all the way to the Pacific Ocean, jumping both the 101 Freeway and Pacific Coast Highway in the process.
100's of homes have burned....and more are burning right now in Malibu.

Interesting so someone still replaced the studs on the Dana61 rear axle. Is that something they could have done or would the entire axle hub have been replaced?
Also sorry to hear! Stay safe out there, I've got a little bit of the fire on the news but hadnt heard too much. Right now we are in the 20s and 10s. Hope the fire stays away from you!
Edit* also yes in your earlier post I remember you did mention the Dana61 was still 1/2". Wondering why mine ended up with 9/16" but who the heck knows with my PO.
