this is how the add reads on CL but im not sure. first, did they make 1.5 ton 60s? i heard of this before, but arnt all 60s just one tons or are their some 1.5 tons? and 2nd can you use rockwell outers on a 60?

"i have a front and rear 1.5 ton military axles. the front is a dana 60 with 2.5 ton rockwell outers it is locked and has 6:87 gear and high steer. the rear is a dana 70 with rockwell outers it is locked and has 6:87 gears. i also have a set of 15 inch rims to go with them. im looking to trade for a set of 1 ton axles or a set of built toyota axles."
 
Link?

The military did rate many pickups and similar chassis' as 5/4 ton, though nothing was different from a civilian truck other than maybe rear springs. Same axles.

Why Rockwell outers? A set of good shafts and joints in a 60 (35 spline inner and outer) will typically move the weak point to the D60 ring and pinion, even if it's a high pinion. Especially with a really low ring and pinion ratio.
 
what does high pinion mean? is it just high geared like 3.08s and higher? or is it somthing diffrent all together?

Nope, high pinion has to do with the relation of the pinion gear to the ring gear center line. On an automotive ring and pinion, the pinion gear is set higher or lower than the ring gear center and that is what is called "high pinion" and "low pinion".

One quick note that is important is that there is a drive side and a coast side on a ring and pinion, the drive side is stronger (supposedly by 30%).

In a rear application, a low pinion diff will apply power to the drive side of the gear when you're going forward. This is the strongest way to go and it's the only way that the OEM's ever used, high pinion rears are purely aftermarket.

In a front application, high pinion diffs are stronger because they are applying power to the drive side of the gear when going forward. Low pinion front diffs (like Chevy and Dodge front axles) are applying power to the coast side of the gear and aren't as strong, usually not a huge issue for most.

The high pinion in a front application is ~30% stronger in the ring and pinon setup. My point was that even a regular D60 with off the shelf parts can make the ring and pinion the weak point, so what's the point of using Rockwell outers? And what does that really mean anyway? What shafts in the diff? What axle u-joint? I would imagine it's rockwell knuckles/hubs, but what outers?
 
without a picture, my first guess would be that he is a window licker and has a pair of closed knuckle dana 70's... do a google image search http://www.google.com/search?q=clos...&source=og&sa=N&hl=en&tab=wi&biw=1366&bih=587 and you could see how someone who has never worked on a rockwell could confuse it with being "rockwell outers."

high pinion would be referring to the pinion gear being above the axle centerline.
 
Amboid and hypoid is what high and low pinion gearsets are called. Ford 9" pinion is on centerline.

and the old dana 70 closed knuckles were big 6 bolt pattern and drum brakes and fitted with super low gears.

vary easy to get mixed up with rockwells if you lick to many windows on the bus as a kid. :haha:

pic#1 = closed knuckle axle with king pins.

pic#2 = big 6 pattern on old style dana axles from m715 trucks and drive flanges on ends of axle.

pic#3 = big 6 pattern end of a 2.5 ton axle.

pic#4 = no brakes on a front 2.5 ton axle.

pic#5 = 2.5 ton rockwell axles.

now you can see why thay get mixed up so easy to the stupid people.

i agree. likely the d70 closed knuckles. Reminds me of the argument I had with a guy this week about how gm military trucks never used dana 60s, and the 1.25 ton trucks were some crazy axles that nobody runs..
 
I think that is the most logical thought, most likely M715 axles, and if it is, they are NOT worth anywhere near what he thinks they are.
 
he sent me some pics. looks like he did use rockwell outers. looks like a weaker set up than dana 60 knuckles

These ARE M715 stock axles.
The rockwell axles are square, you should see that transition at some point if he had done what he says he has.
Anyway from what I see, offer him $250 for the set, if he doesn't bite walk away.
 
Even if he did use rockwell outers... would you trust it? Look at his spring plates. Looks like a lot of half assed work.
 
no im not going to buy them. Hillbillywizard has a CUCV M1008 Dana 60 for $1100 im trying to get from him. the cucv axles are the same as any other dana 60 axle right? well worth $1100 if it has new rotors, pads, ball joints, kingpin, ext. anyone know what all involved when the military refurbishes a axle?
