Front Dana 70 Open Knuckle, Pictures??

Hey everyone, i'm in need for some pictures of an opne knuckle dana 70 front axle, i have search the board for a couple days with no results, and i am wondering if anyone can help me out here, as i have a chance to aquire one for a decent price from out of some forklift or something (i got lucky to as its within a usseable lenght, a little wider than the truck, but its for the mud so it don't matter to much) like that, if possible a good front picture and a good of of the rear that shows everything would be appreciated.

Thanks.

Dana 70 fronts look just like Dana 60 fronts, just the pumpkin is a little bigger.

all the dana 70 fronts i have ever seen were closed knuckles. the only open knuckle ones i have seen had 60 inners machined and put on them. i think the only advantage is the bigger ring gear, and i think it has less ground clearance. iirc they take the same axles as the dana 60. i had 2 of them, and did not want to go through the trouble of replacing the c's so i traded them for a 60

They made Dana 70 open knuckle, but I don't think that any trucks came factory with them. I think that aftermarket companies doing 4x4 conversions on vans and motorhomes used them. Quigley for one.

Steve has 70 open knuckel king pin axles BUT wait not the same as a 60 king pin stuff its a king pin/knuckel combo big enough to use rockwell size u joints, they also use standard chevy type wheel hubs, spindles, and brakes

I have had these dana 70's laying around for 6 years, these were for front wheel drive motorhomes. This is a very LARGE tube fork and the steering knuckle is a stretched style dana 60, using chevy dana 60 parts top and bottom and all other parts. In the pic this is a 2 1/2 ton rockell axle and it clears very easy. I plan on reproducing these two items. steve differential eng. inc.

Well through my research there were dodge W600's and IHC 1600 that used the open knuckle dana 70. The difference's between the 70's and 60's were that the 70's used the bigger centersection (gears and such), the bigger/strong 3.5" tubes, as well as bigger inner c's, the only thing that were the same between the 70 and 60 were the rotor's, inner axles (stubs were 35spline on open knuckle 70's), calipers and spindles, and 35spl hubs intercahnge between the 2 as well as the stubs. I think that i will have to give a call to that wreckers i called today and see what that 12000lb front drive axle was (might just be an 80, that would be cool), but if this deal doesn't work out anyone know (or have) wher i can get some a good deal on a front 70 i can use in my competition bogger?

Oh and even though those pictures aren't of a 70, they help and give me a better idea.

The dodge W600 is closed knuckle with tracta joints 1967 to 1975, U joint 1974 to 1978. The IH 1300 and 1600 are U joint, closed knuckle. There is no dana 80 front made by dana for hwy. use. steve

and yet another thing learned, those used the 35spline outers as well, i thought the closed knuckle axles all used the 19 or 21 (can't for sure remember, i would have to look at the couple charts i have) spline outers, while on the subject, can the hubs (drive flanges, as that is what i want to use) from a closed knuckle axle be used on an open kunckle axle?

I have some pictures of my open knuckle dana 70 front but I can't post them, if someone wants to host them I could e-mail them to someone.
My dana 70 front is from a big front steer front wheel drive fork lift and it is the same width as a GM dana 60.

I don't know about the Dodge part of that, but IH was using the D70 with closed knuckles and the large 6 lug pattern on their 1600 Loadstars and S-series trucks into the 80's, I don't think they used an open knuckle version.

EDIT: there was just a thread about this in the Chevy forum...well sorta. Some late model 3500HD trucks (that had 10 lug wheels and the extended grille) were converted by aftermarket companies to 4x4, and they used a 10 lug open knuckle D70 up front, and a D80 in the rear.

Yeah i know about the converted chevs too, i found the website of the company that does the conversion a couple night ago, they are usually sent to firehouse's in rural/rough areas where something like this is needed.

The IH 1300 and 1600 from 1968 to 1978, closed knuckle came with 35 spline inner and outer, this stub was 11 1/32 long 35 spline - solid dive cap, no locking hub. steve

Steve, isnt a 1480 rated for at least 1.5 tons, i thought a 1410 was 1.25 or 1.5, so 1480 has to be at least that?? am i missing something here??

thanks

You are confusing ratings for use in the driveshaft with axle-shaft ratings. Yea, 1410 is kickbutt going into the R&P but put 5.13 torque multiplication into it and
