i need a set of axles for my dana 70 posi track...for my pulling truck...broke the 60 had to go bigger to much motor....what would be the best set up on axles and gear

 

corporate 14...

35 spline 4340 chromo shafts are available for the d70 cheap

what did you break on the d60? surely you werent pulling with the tiny 30 spline rear axles

the 14ff aka 'The Plow' might be ok for pulling, I think aftermarket shaft selection is far more limited then staying with Dana
personally I do not like the 14ff at all. housing shape is the worst available for clearance, 30 spline oddball shafts, hubs are built inside out inregards to getting bearings and races into it
the only plus I see is the threaded adjusters and I dont set gears that often to need it

 

I have heard this before and personally I just don't see it. I have a d60 rear sitting here next to a 14b and don't see the issue.

That seems to be besides the point on a pulling truck anyways, as I am pretty sure ground clearance isn't an issue on these trucks.

 

I'm in the same boat. I just destroyed my dana 60. Now I'm looking for an upgrade. Nitemare, I don't know where you are at, or what class you are pulling in, but here in the stock class in Indiana, you have to run an axle that was available in your make of truck. Therefore, you would have to put a dana or sterling in it. My personal suggestion would be a dana 70 or dana 80.

 

What Ford trucks did the D80's come in?

I know you can find an 80 out of a 94 (pretty sure it started in 94 - I know it wasn't 93) or later Dodge Ram with a cummins.

 

Nitemare, depending on your rules/budget I think you would be better off going to a 1050 14 bolt (the 14 bolt ff that m j is referring to), AAM 1150 14 bolt, sterling 10.25/10.50, or a dana 80. The 1050 14 bolt is readily available and superior to the dana 70. If you stay with the 70 the next problem you will have will be twisting off the pinion shaft as they are the same size as a dana 60's. I run a 4x2 modified and the old man runs a 4x4 modified pulling truck, and we are now both running the AAM 1150 14 bolt as he went through something like 5 or 6 ring gears in one season when he was running the 1050 14 bolt. The dana 80 and 1150 are essentially equal in strength. The 80 is more common and available in many ratios but is usually more expensive than the 1150, which has limited ratios available. If you have to stay with an axle that was available in a ford, then a sterling 10.50 or 10.25 would be a cheaper alternative to the 80 although obviously not as strong. No ford truck ever came with a srw dana 80 as it only came in drw f350s and older f450s (before '05 with the larger 8 bolt lug pattern). The srw dana 80 only came in a dodge as far as I know, with the same outers as the dodge dana 70HD. Any more questions just ask.

 

compare the housings to a d70U (or even the d60U) and you will see what I am talking about.

rear d60s are not an upgrade axle and I wouldnt recommend them in any truck
most of them have a spindle bore that will not accept 35spline axles without boring

as was stated the 60 and 70 share pinion yokes

we still need to hear an application before we can say how far he needs to go in axle sizing.

 

I will try and remember to take a look again (and even get some pics so others can see) this weekend. I have had all 3 (just dumped the 70) and I just don't see how a 14B is worse. Again - I'll try and remember to snap some photos.

 

if you have ever seen a d70u then you will know how a vertical cast cover rail is worse then a smoothed housing
d70u is found in 1983+ fords
there are 70s that look the same as your average d60, but even the 1990 dodge d70 I had was better then the 14ff I replaced

 

Still not agreeing with you on this one. The D70u out of my 91 Dodge/Cummins was a bit bigger than the 60's in my old Fords, and neither seem to have a ton more ground clearance than the 14ff.

 

Many 70U's are piles, and not very desireable. Many of these 70U's have 32 spline axles, and are not good. Are we looking at ground clearance or strength here? Above is mentioned that the 14B is superior and it is. Third bearing support for the pinion, a shorter pinion and larger bearings make the 14B stronger.
Dont be fooled by the 30 spline axles of the 14B, you woht be breaking these any time soon.
If you are looking at ground clearance, then the 14B ins again, though while stock it has less clearance than the Dana's but it can easilly be shaved to provide far greater clearance than any dana. Shaving a sterling does little for clearance, but the 14B can be shaved to be real close to D44 ranges with regards to clearance.
For overall strength, it is tough to beat the 14B.
The real killer for pulling trucks is a change in pitch line, this is the contact area between the ring and the pinion, and as these gears try to seperate the tolerances change, and any change is not a positve thing. This is why danas tear up rings and pinions. The solution is to add a pinion support. Since the dana case cant accomodate this, the 14B has a distinct advantage.

Here is one of many busted D70 shafts........


I own both, a 70HD, and

 

the third pinion is due to the other pinion bearings being too close together

the dodge dif is nothing like the ford d70u, had the 32 spline dodge one in my chev (replaced a 14ff with it so obviously I found a difference even with having to swap axleshafts to 35 spline), have the 35 spline ford d70u in my ford
housing SHAPE, one is a wall one is smooth as a baby's bottom
I have helped a few people chop a 14ff for clearance, none into the ring gear. most leak. a lot of work to equal a d70u
I have heard the d44 range story before too, and I do not buy a 10.5 ring competing with a 8.875 ring but it sounds good

easy to swap in 35 spline axles into a 32 spline d70, buy the detroit in 35 and matching axles, I used off the shelf dana shafts when I did it

 

I used to talk down about the 14b, after research-and hearing stuff in here-Im gettin one. Even if I do only one gear change-the ease will be nice. Pressing bearings on and off for shimming, ain't fun, even with a good press. By the time I bought a 14b-did a minor shave, locker, and thick diff. cover-would probly be cheaper than getting a sterling, or d70, and having to do any mods.

I have a question tho, about wheel mount spacing-wms? How important is it to have front and back axles equal, or as close as possible?

 

so guys what if im upgrading the dana 70 i blew apart the 60 if someone can juss get me to a website that i can check out some axles or sterling setups...thanks
