I have a chevy front axle going in under my truck. width of 69", which is great.
however, a 12bolt isuzu rear axle at 58" won't do.
i want to swap a dana 60 rear in my troop. what do i need to look for? i want to run 37x13inch boggers. on a Dana 60 15inch rims won't work due to the larger drum brakes, right? which dana 60's had 35 spline axle shafts and 30 splines? i've tried to search but information on rear 60s seems to be pretty limited.

try lookin for a d60 from like a 76' F-350. i got one of those if you are interested. it's built, no locker, 30 spliner. new drum brakes. and you can run an 8-lug 15" rim on the drums too. i've tested it before with one. your only problem for a 15" 8-lug rim might come up front with those discs though. you'd had to shave the calipers to make em' fit. my rear 60 is 65" by the way... still full-wdth, can always add spacers, plus wider axle up front helps for a better track width, good on the trails :cool2: let me know, otherwise, this info should still help, pce.

is your front D44 8 lug?

rear 60's are dime a dozen really.................i would strongly suggest going w/ something full floating and swapping the front to 8-lug outters.

you "can" find a FF rear D60......but more likely and cheaper would be a GM 14bolt

pretty much comes in every chevy 3/4 and 1 ton (2500-3500 chevy/gmc) truck and van on the road for tha last 30+ years. the gears are a little pricey, but the cost of a detroit offsets it. and the axles are 35 spline.

just a thought.

if its semi-float, it will have 35 spline. If its full float, then you get 30 spline. its possible to build a 35 spline full floater, but it takes reaming out the spindles.

another alternative to consider is what matt mentioned, chevy 14bff.... tons easier to find, cheaper to build. its what i'm running in the rear of my Rodeo.

my front is 6lug. so i'm gonna need 8 lug outers.
now i must find a full floating dana 60. from what i've read they come in fords.

yeah i would do the 14bolt but i want to run the highest gear ratio possible. atleast 5.38s. i'm runnin the 2.8 still and don't want to let go.

thanks for the info.

dodges have been running 60's/70's also for about 30-35 years.

well also be aware of the D61

these are FF D60 "looking" axles w/ 35 spline inners....................BUT they have a Numerically LOW ratio carrier (3.73 -) and you can only run up to a 4.56 in them.

do a search on D61 and you will get some what to "watch out for " info.

i mistakenly picked up one of those last year thinking it was a 35 spline ff rear D60.....silly me.

if anybody can use it i'll let it go DIRT cheap to get it out of here.

how about this one....
i was talking to the owner, he said it came from a military f350 that got hit in the front. i took a look at it. it looks huge, i'm used to my 12bolt and 44's. this thing is gigantic. could this creature be a dana 70? i'm problaby overdoing it, i'm used to lookin at my friends shaved 60's.

No fill plug on the diff cover which pretty much cancel out any of the dana axles, looks like a GM 14-bolt to me. If he said that it came out of ford it is probably the Sterling rear but it damn sure looks like a 14-bolt doesnt really have the center section look of the Sterling. The sterling is a Big bastard but very few gear ratios available for it.

negative...................that is not a 14 bolt.

look again, there is a plug on the cover. i would say it's possible a D70 rear. 70's and 60's use the same cover ............but the 70 is a 10.5" ring gear.


look on the axle tube to the right of the diff (back of axle tube) and pull the Bill of Materials # (BOM) and plug it in here to find out all the details of this axle:

oh year....axle in the back is a D61.........notice the extra rib across the top and the FF hubs......this is the one to avoid

i'm pretty sure it had a filler plug on the top front side of the diff like a ford 8.8.

that thing looks like an 80, friend of mine has one under a fullsize bronco and with 35's it almost drags

its the sterling 10.25 i just looked at a ford 250 in the parking lot. damn it.

Look again there is NOTa drain plug, looks just some crap on the cover. Dana Axles have a very pronounced Square Drive Drain plug that stick out about 2-2.5"

Ever seen a semi-float 14bolt looks alot like the axle in the pic.

I know what a 14-bolt FF (in your pic) looks like and is, I couldnt really tell with the weeds covering the bottom part of the axle, My way of Identifying a Sterling, I merely listed some possibilites. Like I said it looked like a 14-bolt because of the similar looking diff cover, but I also suggested the Sterling rear.

But like you said just get the BOM number and run it.

I found this site has everything www.drivetrainsuperstores.com for Dana axles

:emb2: DUH, it says 93 f-350 (or 250) right on it............didn't see it before

that is a sterling 10.25 rear...............the ridged casting on the diff gussets give it away.....and yes on second look, doesn't have the square spicer plug.

i also have one in my f-250........so i do know what that looks like :D
good axle but limited gearing for them............so i still wouldn't use it for this project. Seems like you would need lower that 4.56

And why not run a Dana61? There's a few internal mods (like using a 60 carrier and a spacer) otherwise it comes with shafts and everything. Personally, I'd rather deal with the carrier and spacer rather than boring out the spindles and ordering new axle shafts....

edit: http://www.pirate4x4.com/forum/showthread.php?t=245900&highlight=carrier

i guess i'm saying that in some applications the D61 would not be worth the trouble. especially when other axle are prevelent and easier/cheaper to build.

the isuzu trucks come with 4.56 from the factory.......and the typical gear choices are 5.13 and 5.38 for guys using the stock motors and big tires.

it can be done, but the D61 adds another level of tech to the guys "virgin" stab at swapping in a larger rear.


just suggesting the path of least resistance :)

i bought a dana 60 at the bone yard today. i took out one shaft and low and behold 16 splines. son of a bitch.

fawk :(

dude, i'll sell you my d60 rear if you want? im sellin it anyways because i decided not to go fullwidth because i didnt have enough $$ right now to have 2 cars. instead i went yota axles. let me know quick if you want, i can ship and can arrange so that the price is fair, pm me or post here and let me know. just tryin to help a brotha out.

why does your dana 60 look like a 61? with that ridge on the top?

i found this one at the bone yard today, going to pull the shafts before i get it in the garage.

Goodeye slinger, he's probably selling it because he found out that it was 61 and its going to be a PITA to do anything with.

Notice how anxious he is to get rid of it :shaking:

after looking at the number of dana full floating axles i feel like some sort of expert now. the one pictured is a dana 70. the larger housing gives that away. i'm all set, my buddy has 30 spline axles for me, 2 sets of them. he says i can slide them in and go with a 30 spline diff and i'll be all good. detroit it is.

that pick was the bottom of the axle anyway :rolleyes:

look at the spring perches :flipoff2:

congrats on coming up w/ something.

Don't eliminate the Ford 9" probably the best choice. I have one in hand now, and wish I had gone ford 9" instead of my Isuzu 12 bolt. (8 3/4"). Fabulous choice of lockers, axles, you name it. Good mate with the Dana 44 front as the early Bronco boys can tell you.

9" description doesn't do these ring gears justice. The width of the ring gear dwarfs a Dana 60. Also much, much smaller than a gm 14 bolt which is HUGE. Much too huge for an off roader, Mathew to the contrary. Even too big for 40" tires IMO. Some shave them.

SunRay Engineering in Weatherford Texas makes great use of the Ford 9" diff. Even using them on hybrid Ford 9"/Dana 60 knuckle front setups. Saw them in person and am really impressed.

The ford 9" construction is very similar to the Isuzu 12 bolt..
