3/4 ton axles

[Dova]

what's the common 3/4 ton axles for 4wd's i have one i can't remember the rear end is a 14 bolt and the front end came with it is it a dana 44?

[69-350]

should be. Dana 60's weren't used until the 73-up 1-ton 4WD. Dana 44's were used in 3/4 tons, and half tons used 44s until sometime between 78 and 81, after which they used ten bolt front axles.

14 bolts showed up in 73. 67-72 trucks have either Dana 60 or Eaton axle. Dana 44 is all that would be in the front. Disc brakes 71-72, drums the others.

Hah, forgot about the rears. Kinda important. Look out for the Eaton ones. Good axles, as far as I've heard about, but once you break them, they're done, simply because of the lack of availability of parts. I almost bought a K20 once, drove to Bismarck, like a 3, 3.5 hour drive, through slushy to icy conditions, 68350 was driving most of the way and at one point almost went into the ditch passing a semi... black ice. Anyways, almost bought a K20 that had an Eaton. No that's not what scared me away. The lack of the guy telling me they hacked out the entire firewall around the tranny hump (from bottom to nearly the cowl level) to fit the 455 Olds after they took out the 6" body lift is what scared me away. I wasn't going to pay as much as 700 bucks for a truck where the cab is hacked, the tires are about rotted and too small anyways, there's an Eaton rear, a bad 455 Rocket and god knows what to the tranny, and the thing used to be a mud runner. Some people are crazy.

You sure about the rear though? I thought 69-72 4WDs came with 14 bolt rears, along side the Eatons?

What year is the truck?The Dana60 front end never came in a K/20 and not until`77 (I believe) in K/30s.GM went to the 10-bolt front end in (I`m guessing)`78?`80?Somewhere around there.Never had a 4wd between `72 and`84,personally.So not real sure.

Dana 60s are one ton front ends only, almost everybody, except Dodge, who put them in 3/4 tons equiped with the Cummins. Not sure when they began Dana 60 fronts though, maybe when they started 1 ton 4WDs? Somewhere between 78-81 they phased out 44 fronts, according to what I've read. I'm assuming 78 they started the 10 bolt and mixed and matched trucks until 81 when they stop putting even one 44 in anything.

I guess I kinda forgot to mention Ford. I mean, it is easy to forget them, haha. D60s were harder to find in 3/4 ton Fords though, weren't they? I know the ones to get are 78-79 F350/F250"Heavy Duty" (snowplow optioned, etc) High Pinioned 60's, drivers side diff, for 88-98 SAS. But beyond that, they were rare in 3/4 tons, am I right? They are Fords, I am kinda vague about them, and only slightly less vague about Dodge.

For the Chevy IFS to SAS, I prefer the later model Furd D60s... they're wider. The again, the last two 92-2006 Chevy SAS's I did were coil over and four link.

I think I'll do leafs. I've thought about coils though. Not sure. Not even real sure on if/when to do SAS. I'm still thinkin of puttin in the 9.25 IFS diff in, with all that work involved. I wish Dodges were drivers diff, cause my bud's go a D60 soon, and he owes me money. Time for a SAS and 205 swap maybe?

Dodge W200s had Dana60s in the late`80s for sure.I know a guy who ordered a cab`n`chassis one ton`70 4wd.I never went to see it,but believe this guy.I believe they put a D44 in there.The front didn`t have budd wheels.

hah. One day maybe I'll post a build thread in the 88-98 board. Spread some FullsizeChevy wealth unto these boards. Haha.

So now that's we've totally hijacked the thread, going back to Dova, check what the front is. It's not hard to replace the front axle with something else. Who knows what somebody did. I've come to learn a lot of PO's are lunatics.

From trucks I've seen over the years, 1/2t got a 44 up to 78-ish, 3/4t up to 80, which can depend gears. Pre 73 got Eatons, up to 80 all 3/4 and 1 tons got the 14ff. After that, hit or miss on 3/4 getting a full floater.

GM never put 60s in 3/4t, only 1 tons. That started in 77. They did have 1 tons prior to that, but just got the 44hd with big lockouts. Few and far between.

Fords and Dodges put 60s in 3/4t, just about all the 60s that I've had were from a 3/4. Dodge started in the mid 70s, not sure exactly when. Ford did some stupid stuff, a low pinion 60 in 75-77s or something. Then 77.5 started the high pinion. In the 80s, only the 1 tons got the 60s again. Dodge could be either a 3/4 or a 1 ton to get one.

When did Dodge get away rom the internal hub?They weren`t Dana60s were they?wasn`t that into the`80s?
This is good discussion.It`s not really a hijack.We`re just borrowing the thread until Dova comes back with what his truck is.

Well, it got moved anyways. Haha. Took me til a few posts ago to realize that! haha. Informative thread anyways. I'm always a nerd for information, even if it's mostly useless to me.

according to the info from dana spicer i have, dodge and international both started using the "good" D60 in 1975...which was disc brakes, kingpins, all the good stuff. of course 1975 was the last year for international light trucks (except for the scout II), but the dodges used the external hub D60 until the early 90's. they only used the internal hubbed 60s for a few years, '93 being the last.

Fords used the HP60 in '78/79, then they dropped all solid front axles from their lineup from '80-85ish, when the F350's got HP60's back. I think 1991 was when they switched to balljoint knuckles, but i'm not sure.

As for the Ford stuff, I believe you are right. Main reason I know this... read any post on a SAS and they recommend which axles to use and not use. Kingpin knuckles, good. Balljoints, bad. 78-79 high pinion D60s in all F350s and the heavier duty F250's. Fast forward to 91 and they came back, with balljoints.

Now it`s a Dana50 in Fords? or something like that,isn`t it?

They came in the picture somewhere. I think in the twin traction beam era.

[special-K]

My BIL`s F350 has one,a solid one.It`s about a`99 I think.

D50 up front? I think they did put them in still. I'd have to research more into it later, but I believe you're right.
