I can get a d70 closed knuckle front axle from a 1968 IH truck for next to nothing and wondered if anyone knew anything about these axles.

1. shaft diameter, spline count

2. u-joint size

3. stub axle spine count

It's a 6 lub, big pattern, for dual wheels.

Thanks,

'tswaylo

searched already:D

It's more or less junk for wheelin'. It's good for a 1T pickup.

I don't know all of the specifics, but you won't find 35sp stubs, it's closed knuckle, either small U-joints or tractajoints, the 6-lug Budd pattern is a PITA - drums are hard/impossible to find, and so are non-split rims.

OTOH, if you need to carry 4500lbs..

PM Mossberg on this board, he runs one with tracta joints in the front of his toyota, he has posted several threads about them.

turning radius sucks weaker than d60 U-joints large 6 bolt pattern is a bitch to work with but it can cary lots of weight

was there ever any other kind of front dana 70

Not used by IH, so its safe to say there were no other automotive production uses.
Every industrial D70 I've seen was closed knuckle.

I wonder how hard it would be to run a 70 w/ D60 knuckles,stubs, ect.

I went ahead and bought it and tore it down. Here's what I found:

inner axle diameter: 1.50"
inner axle spline count: 23

stub axle diameter: 1.375"
stub axle spline count: 21

inner and stub axles both neck down between splines and yokes, like Ford d60

axle joint is the same as d60, no tracta joint

diff is a Dana Powr-Lok

gear ratio: 4.88:1

with minor machining of the spindle, Ford d60 or TTB d50 spindles, hubs, and rotors will bolt to the outer knuckle

just a little fab work to make caliper brackets, and I'll soon have a disc braked, closed knuckle d70 with 8x6.5 lug pattern and about 68" WMS to WMS

it was worth the $150 if only to see what it was made of

Dodge W300's up to '71 had Dana 70 front - 8-lug though.

Jeep 5/4-ton military M715(?) used them too - in a big 6-lug.

Both are closed knuckle.

Let's see some pics of what you do to convert to 8-lug disc brakes.... My buddy has the Dodge D70 and is stuck for ideas.

congrats


you just fucked an very rear model of truck

i'de give my left nut for my 68 to be a factory 1 ton 4x4

(for the load capasity not for the :rainbow: axed shaft diameter)

As it gets put back together, I'll try to put up some pictures.

Basically, the OD of the spindle shoulder (the part that sticks into the knuckle) will have to be turned down about 1/8" and the mounting holes in the spindle face will need to be elongated or new ones drilled. The 70 knuckle uses the same odd-5 spindle bolt pattern as Ford d60, but it is a slightly larger pattern.

Getting clearance between the knuckle ball and a caliper may be a PITA. I'm going to experiment with using a d60, d70 or 14 bolt rear hub on the Ford d60 front spindle to play with rotor offset and also to see if there is any way I can make an adaptor to use the gigantic IH lockouts.

To me it's fun to mix and match and see what combos will work together and what won't, so I'm pretty anxious to start tinkerin' with this outer stuff.

was there ever any other kind of front dana 70

I have SEEN an open knuckle 70 front, with disk brakes and 8-lug pattern in a late-75 1-ton IH dump. It does exist, 35 spline shit, but heavy as fawk. This truck also had the strange rear-exit exhaust manafolds.

Cheif, you'll be glad to know that the truck the axle came from was completely trashed (no bed, cab rotted away, junk frame).

If you're interested, I have another d70 front axle and the transfer case from a 196? 1310 that I'd sell. How much is your left nut worth?

:D

well your a little far but whats it worth to ya

I hoped the 68 was trached to begin with

YEA, How much for the 70????? (I need a SRW one, have the 1300 dually 4X already, havent been able to find a SRW one yet) Do they run budds on the SRW's??

Budd's are dually rims dumb ass :rolleyes:

Do you still have the dana 70 front?
I'm looking for a set of 21 spline lockouts for my axle.
I have 1 35 spline lockout in great shape I may trade or sell.

DON'T USE THE LOCKOUTS!! Use a hub flange instead. The lockouts ARE expensive and rare. They also won't hold up to much power with big tires.
As for changing a CK 70 to 35 spline its no big deal. Just need access to a lathe to modify the spindle and its a bolt together. I built my own 70 CK to be a center diff for my rear steer. 35 spline inners and outers. :D

Thanks for the reply.

I will be using this under my 1 ton truck so i want to unlock the hubs when i dont need 4wd. I will be running the stock 17.5 wheels so breaking will not be a problem. the axle had 21 spline outter shafts and 1 21 spline lockout and 1 35 spline lockout. someone down the line didn't get the correct lockout.

just for reference, there is also a Chebby Dana 70 open knuckles (probably mid 70's to mid 80's) people around here put the 35 spline outters in 60's as an upgrade. So far Warn is the only one who makes a 35 spline lockout thaat I know of. The Power-lok can be upgraded as well if you want to upgrade to Moser or heavy duty 35 spline inners. Just replace the side gears. Did it in mine. Now going to Rockwells, though.

M715s did NOT use a dana 70 front, they used a closed knuckle 60 front, with a 60 rear.

Hey chico.. they used a dana 70 rear :rolleyes:

Budd's are dually rims dumb ass :rolleyes: Buds are a lugnut patent... :shaking: I have budd stamped on my newly puchased dana 70 front with 8 on 6-1/2 BUDD hubs and nuts! I will have pix for you tommorrow at http://autos.groups.yahoo.com/group/CJ-10A/ I will also show that the 70 IS a much stouter front than my 3500 dually d-60 and i think will hold up well in any use especialy in my CJ-10 under a 13.5:1 alky drinkin 440 wedge :smokin:

If anyone is looking for D70 parts, I have everything from the ball outwards including a set of the BIG lockouts (68 and older 6 lug style). I have a housing that I am converting over and using 1 ton Chevy stuff for the outers plus updating the axle shafts to 35 spline inner and outer. Wasn't someone working on 40 spline stuff? Wonder what's involved in putting 40 spline in? At any rate, I had always heard that a 70 housing is thin. I don't know where that comes from because the tubes in mine are twice as thick as any 60 I have ever seen. I don't care what it weighs when I'm domne becasue I have 1000 pounds of engine perched out on the front end of the frame. I need all the carrying capacity that I can.

IH dana 70 fronts also came in 5 lug version, I have a 75 or 76 1600 4x4 with one. No idea what it has for internals though. It is actually ten lug budd pattern but only half the lugs are there on the front axle. Here's pic, nope, mozilla and ie are both f***ed today. will try pic later.
http://www.pbase.com/txs/image/29163780 Had to shut puter down and start over, the window with the pic url would not show.

The housing I got is a 311 something 73 or 311*73 can't read the one number??? It is also a "B" housing I have been told there is an A,B,and C housings. Don't know the difference myself? It is 8 on 6-1/2" budd hub and nuts. 4:88 gears and has no u-joints but the tracta type Joint. http://home.wmol.com/mechaniq/Images/PWSpecs/F375.htm
These 70 axles where used in military vehicles for years and some IH trucks and snow plows and such as you have read. They ARE Very strong and heavy built that is for sure. It weighs in at almost double the 60 axle. According to my bro in law he worked on them for years and saw very few fail. He also said the Tracta joint is strong as strong as or stronger than the Dana 60 stuff that came latter. He said he has replaced lots of axles and u-joints even in the lighter trucks. He said that the military mechanics loved the tracta closed knuckle because they never had to work on them as much because of the closed design they had no lube, foreign objects, or dirt problems ever! They also can be under water for hours and have no ill effects since the round knuckle joint is filled full with grease and all the maintenance after a week of swamps is pump it with grease again. Steam cleaning and hose down is never a problem like it can be with u-joint seals being damaged by high pressure washing and metal and sticks catching in the joints he said. He also added he never had a round knuckle joint spread like the newer C-type from jumping and abuse. They are great for mud boggin or serious wheelin with large tires and you will probably never break one. But the question is what do YOU plan on doing? IF I was building a competion rock crawler for Moab would a 70 a good choice? Not really... I would use the LIGHTEST axle I could find that is still strong enough. I would use the Dana 44-hd housing and add 60 outer parts with the best axles and joints I could afford. Is a Dana 70 better than a Rockwell or Mog? In some ways for 95% of us that are recreational wheelers, absolutely yes! I would use one on anything short of monster truck. Remember the D-70 is used as a 1 ton to 2 ton front axle so it is stronger than a 60 for sure but lighter than a 2-1/2 ton and up axle (Rockwell or Eaton). Another thing is 70 parts are everyplace except maybe the tracta joints but most TRUCK shops like six states will have something for you or even truck junk yards. The IH 4X4 dump truck was all over in the 80's so the bone yards will have them for extra parts. If you can build enough power to shear a 1-1/2" axle or pinion shaft you are at a different level than a d70 or even a Rockwell can provide anyway.

If anyone is looking for D70 parts, I have everything from the ball outwards including a set of the BIG lockouts (68 and older 6 lug style). I have a housing that I am converting over and using 1 ton Chevy stuff for the outers plus updating the axle shafts to 35 spline inner and outer. Wasn't someone working on 40 spline stuff?

If you have anything left of the D70 front parts, send me a list of what you have and a phone number. I have a buddy that has some of these and wants spare parts.
