Its free, just sitting in a yard. A detroit is what like $380 for these things, but you need 35 spline axles, anything stopping me from getting some yukon 35 splines for the D70?

i think this would be easier/cheaper than finding/machining a D60 to fit 35 spline and then buying a locker as well.

How about a Dana 80, we can get one for $300 with discs from a 2005 truck.

I don't see any reason that wouldn't work if you don't mind paying the price for the yukon shafts... If it were me, I'd shop around for a d70U with 35spline shafts stock and save my money..

I consider the d70 overkill itself, do you really have enough motor to justify dropping that beast of a d80 under there?

just trying to think of whatever is going to be the most cost effective. I cant find any 60's around here cheap, and the ones that are need to have the housing ends bored for 35 spline.

the 80 is a lim-slip so i would need to find an open carrier to weld the spider gears, but it also already has Discs on it.

ideal is a D60 that doesnt need the housing bored + 35 spline shafts+ spool.
thats about $300 total, add in brake rotors, caliper bracket and calipers and its around $420. almost forgot gears and a install kit. thats $650 total for something thats not going to break.

cant even buy a detroit for that for the 80 or the 70.

so the 70 will be $250 for gears/install + 160 for axles+ 350 for locker + 120 for brakes= 880

the 80 will be 500 for the locker + 250 for gears/install kit + 50 if i find an open carrier for cheap.= $1100

There's a decent thread at Pirate 4x4 about various alloy shafts and their differences. Might be worth looking into.

what year?

watch otu for the old versions. Find out what the offset is on the carrier. there is a 0.625" and a 0.5". This offset is in the housing it self not the carrier. The older 0.5" offset is nearly impossible to find parts for. let alown gears. The 23 spline shafts will be more then plenty for what you goign to do. There are tons of peopel runnign 23 spline with 44" tires and a 350 in a heavy pick up with no problems.

Depending on the hubs and housing you might not be able to swap out the shafts.

It is definatly a better option then reamign out the D60 to support the 35 spline shafts. But for the price of a dana 70 it is smarter to hold out for one with 4.56+ gears and 35 spline shafts. I got mine for free. If your ina pinch there worth liek 100$ thats way cheeper then new shafts and gears.

As far as the locker is concerned. I welded my carrier and i have had ZERO problems.

Oh and the Dana 70 U is the CATS ASS. it is egg shapped and VERY smooth.

Read my article in the write-up section on the Dana 70 and trimmign it they are farly easy to shave down with otu having to weld on a new bottom plate.

was that only available in D600 trucks? What trucks/vans were the desirable D70's available in?

The D70 right now needs a new carrier and axle shafts because the splines look tore up a bit on one side. i will see if its an offset carrier or not.

yeah the 23 spline shafts are huge i can see them holding up fine.

possible to cut the spindles off the D70 and weld onto the D60 so i dont need to do any BS with having the spindles bored?

sell your D70 for a glock. then swallow a bullet.

Just hold out for the 35 spline version. I'm speeking form been there done that experience. making that 23 spline work will cost you more then holding out for a 35 spline version.


dana 70's cane in 1 ton trucks, vans, and D600 - D700 trucks. Some ford delivery vans used them too. the older ones. They are a slut of a axle.

is there a "for sure" application with a D60 that came with spindles large enough to fit 35 spline w/out boring. i've been told the "early 90's ford vans" but when i'm calling around to various junkyards they gotta know the year/model, they are really clueless.

you do knwo that the dana 70 housing is the same size as a dana 60, same size pumkin just a larger pinion and ring gear. Thay also use the same dif cover.

i know they use the same diff cover. Anyways i think i may have it finally figured out. A nearby junkyard (about 35 miles away) is going to piece together a 35 spline 5.13 D70 with me on friday when i go down to their yard. I guess the high numerical gears used to grow on tree's back in the 1960's, find a 4.56 and up carrier that's still good, (open), for 35 spline and then get a D70 housing as well.

This brings up an idea while i'm writing this though, and that is If i use my D70 housing, and just get the 35 spline 4.56 and up carrier, 35 spline shafts, and 5.13/5.38 gears, then i wont need to buy a new housing as well. Its a thought.

theroretically yes you couild. although aroudn the 60's yoru messing with the other offset. that was aroudn the year they switched. get them to check that for you. also the length of your axle tubes and the style of hubs that you have. These axles are sluts and they came in tones of difrent configurations.

My D70 is 23 spline and was a PITA to find shit for it. That is why I went so deep and had to get ARB.

Bought a D70 Dually axle today. got 35 spline shafts, and a 4.56 and higher carrier.

kraqa how much are 5.13's at the junkyard you go too. they didnt have any at mine.

kraqa how much are 5.13's at the junkyard you go too. they didnt have any at mine.

I didn't think 5.13s came stock in any spicer axles... I may be wrong though, I haven't shopped for 60s but for about 5 or 6 hours.

Kraqa

Dana 70's came stock with the following gears

3.54, 3,73, 4.10, 4.56, 4.88, 5.13, 5.86, 6.17, 7.17

i can check on the gears but to be honest i have not priced them for a while. let me get back to you.

k thanks man, i've tried 5 different yards here. they only have gears from the old ones i.e. 1960's. I dont really need brand new gears as this will never get driven on the street.

the 70 housing we got looked like it had some sort of military tire on it. We also saw a 70 that was like 72" wide, it was labeled from a Van. ever heard of one that big. these things were all over the junkyard i was at, but it was hard to find the 35 spline stuff with the "slow" 4.56 and higher case, lots of 4.10's and down cases. he had some 7.17's too, haha.

kraqa have you ever heard of a d70 van axle being over 70" wide?

Kraqa
01-07-2006, 07:02 PM
some of them were super wide 72" i think as you stated. but that doesn't mean the housings were special. the 64" housing is the same as a 67" they just use difrent hubs.

but there is a 69" i dont' knwo what hubs it has. so it verywell could be the same as the 72" again with difrent hubs.

IIRC there are 4 difrent hubs that coudl have come on a dana 70

this axle is a slut.

sounds like i have the same one you do then. at least the width. you are right these things were in ALOT of big trucks.

ptownTSI, you sure on that price for the Detroit? I just put one in my truck and it was a lot more than that. Was for 32 spline shafts though.

ptownTSI
01-08-2006, 11:19 PM
yeah the 35 spline 70 detroit was the cheapest when i was looking.

nate

For some reason the D70s in diesels are 32 spline, and in gassers 35 spline... how does that make sense? :confused:

Even though you have a low spline count you may have a powerlock. They were good working limited slips

i checked on the gears and they were terrible.
