thanks for the info

can anybody confirm or reject this? will gears for a 70U work in a 70HD?

Its also a dually. I haven't been able to find the BOM yet but I am still looking.

I removed a duelly Dana 70B from a 1987 F350 superduty dump body (Not sure if it was orginally in that truck or not but it was when I got it.) The carried is marked C34835-96 followed by 70B. My problem is finding a right hand hub for it as it is different than all the other Dana 70's I've looked at. Does anyone know for sure what years Ford trucks came with the dually Dana 70B? Also, the regular Dana 70 detroit locker and 35 spline axles went right in this unit with no problems? Any help would be appreciated.

How can I tell the difference between a 60 and 70 carrier?It is a 2 piece carrier.Thanks

Here are some pics of my custom-built Front Dana 70:

Um, you mean 9.75 inch.

[gandrimp]

What if I dont have a ring gear? Cause I assumed that was o.d. of the ring gear? Basicly what I have is 2 carriers that appear to be the same 1 is supposed to be a 60 and the other is supposed to be a 70.

CDA, that looks pretty damn sexy.

I am looking into shafts for my rear 70 right now, but I have a question or two hopefully somebody can answer. I snapped my drivers side shaft and have been unable to get the broken piece out of the detroit as of yet (My grandad and brothers pulled the shafts for me since I am overseas right now). The passenger side shaft measeured 39 5/8" long, but I am stumped on how long the drivers side should be. Here is a link to the shafts I have found so far.

37-39.5" shaft

34-36.5" shaft

I have a Dually Chevy D70 if it matters.

I can't remember the official measurement but both shafts on a 70HD are the same length.

Edit: I checked the Dana expert site and the Spicer axle shaft part number is 41100-1 -

Specs for aftermarket shafts
length = 39.69"
spline length = 1.63"
flange dia = 4.47"
bolt pattern = 8 x 3.56"


All of the above info is for 83 K30 dually pickup w/D70HD.

[Grumpy_old_fart]

found a dana 70 with 7.17s, and a powerlock. this thing has locking hubs on the ends of the axles... dodge type with 8 bolts retaining the external hub. its a wide bastard... didnt get a measurement, but will have it shortly.

[cj8scrambld]

Hmm? Dana 70 pinion brake. Any info on it's use/reason?

Edit: Ahh, reason was probably the locking hubs...requiring brakes of some sort..and pinion brakes being the most reasonable alternative...?

[Grumpy_old_fart]

I dont know what kind of equipment it was on, but it was an industrial application. its a funky setup, to be sure.

I think we can sell the lockouts and install regular axles or just find drive flanges for it.

Ha ha, I just read your post, but I had already ordered the Yukons from Ron's about two weeks ago (Insert 'great minds joke!). He had a price on them and he had some super fast shipping, and that was even after he e-mailed me to make sure he was sending out the correct shafts. He said they have the shorter shafts available also, just call or e-mail him about them.

Hey grumpy, does it have some sort of sprocket setup instead of a yoke?
Looks kinda like some D44's I have seen under street sweepers on road construction jobs.

Need some help identifying this one. It's from a Freighliner chasis Utilimaster step van. The only stamped numbers I can find are on the front side of the driverside axle tube, and they don't seem to apply to a BOM.








The shafts have 6 studs/nuts instead of the 8 bolts. It also has the big six lug hubs.

[Red Chevy]

I was gonna say an old dodge military truck with the lug pattern until I saw the disk brakes, got me stumped.

[LS1Jeeper]

Just picked up a D70 I have no idea what it's from. The closest hub seal I could find to the one that was in it was out of a 1990 Dodge DRW. I took it to work and got the drums off.

Definitely isn't from an old Dodge. The step van was a 97.

[Grumpy_old_fart]

i found the BOM on the rear side of the passenger axle tube.

since its a freightliner van, i would think that they used a budd wheel and could pick and choose their pattern upon assembly, and might have gone to the 6 lug hub for weight(GVW) reasons. the disc brakes look heavy duty as hell and are no doubt a factory option. It would be nice to be able to keep them.

Yeah, I was thinking the same thing.

I have seen a few of dana 70s with 6.17 and 7.17 gears that are used in airplane runway tugs. Havent seen one like that yet, but could be something related. I have a friend who works for NMC-Wollard, which is a company that builds airport equipment, and he got a 2 dana 70 rears with 6.17 for pennies. They also got some narrow dana 70 fronts which used equal length short side inners on both sides. I would get pics, but they have already been converted to full width axles.

[LS1Jeeper]

Finally got around to putting the rotors on the hubs and got the wheel studs pressed in. I had to use a 41/64 drill bit. It drilled a .638 hole. I used Dorman studs PN# 610-429 The studs measured .642 and .643. They seemed to fit pretty good and snug.

I have A Dana 70U and looking for A hub conversion to take it from 8 lug to 5 on 5 1/2. I saw it in the offroad mag A few years ago but don't remember the name of the company. Do any of you know the name or any other way to get A 5 on 5 1/2 on the Dana 70U. Thanks.
