2 hub assemblies same axle?

Alright 71 sii and what I thought was stock but it might be turning out different. I tried to find the info on the type of front axle but no luck so far (it is obviously not stock -heard front and rear came drum that year).

I am in the process of replacing calipers and rotors on the front and it looks like I have two different hub assemblies, didnt know that was possible. Anyone shed some light on why or how it ended up that way?

Also, I saw on another thread that the innter nut is 2 1/16", that sound right?

The shaft on the more basic set-up is loose, does that mean the bearing needs replacing?

Damn near anything is possible. Since you are able to post pics, why not post some pics of the actual lockout bodies and of the front diff cover? I think that would really help tell the story. These don't tell me much. Perhaps someone else might be able to get more out of them.
 
Looks like you've still got components from a broken hub on the stub shaft. Remove the snap ring and the parts will come off the shaft and both sides will look the same.
 
Found the info about the axle, there were two tabs on the face plate one has no info the other one is labeled 43-13 and 3.31, obviously the gear ratio. So what does 43-13 call out?

So are you telling me fdchappie that the componenets are not necessary?
 
The 43-13 is a 43 tooth ring gear and a 13 tooth pinion 43/13=3.307692307692308 or 3.31.

You asked about the difference on your hubs. It looks like the guts of one hub is still on the stub shaft. Either the hub with the missing guts is broken or needs to be reassembled.
 
Thank you for the details about the guts. I was more so wondering about which Dana it is though, I am thinking a Dana 30.

Also the rear axle is the same but with drums, so how would I know if someone did a conversion to disc? I am going to be ordering calipers, rotors and possibly some other parts so is there any way to figure out if I need the conversion parts or standard?
 
Front and rear are same...does that mean shape of the diff cover? That would make them both d44's as there was no d30 rear axle option for the Scout. Like I said earlier, a quick pic posted of the diff cover will nail it for you in 2 seconds.
 
Sorry thought the numbers would do the trick with which axle it was. Let me know if the pictures are too crappy because I had to shoot them as I was walking out the door. Thanks guys

Got it thanks. I will post pics of the rear axle and make sure it is a d30 as well.

What about the loose shaft-replace bearing?

And the size of the inner nut?
 
Your rear will be a 44. The 44's began showing up in scouts as early as '65. As I mentioned earlier, there were no 30 rears in scouts, just 27's and 44's. I don't know the size of the retaining nuts offhand, but they are large. A special socket with a thin wall is required and they are megabucks, if you can even find one. You can make one out of a hunk of chain link fence post of the approximate diameter by hammer-forming some hex edges into it. Not a perfect solution, but better than using a hammer and chisel to chip the nuts off and on. I recommend pulling your bearings for cleaning, inspection, repacking, or better yet, replacement. When everything goes back on, the inner nut sets the bearing preload and should be torqued to 50 ft/lbs as the wheel is rotated, which is tough to do if you don't have the special socket attached to a torque wrench. Once properly torqued, the nut is backed off @ 1/8 of a turn. Then the lock washer goes on followed by the lock nut which is torqued to something like 120 ft/lbs...in other words real damn tight.

I been silently browsing this thread in the background, cause my front end has similar issue of p.o. Virus and miss-matched locking hubs. I didn't have a chance to post earlier, that in stock form on the 71, the rear would have been a Dana 44 and the front would have been a Dana 30. Both axles would also have drum brakes. IH did not start up grading the front end to a Dana 44 until mid to late 1974-75. Rotors were added into the mix of things in 73, I think, but definately in 74, and that's on a Dana 30 front end

due to the good ole p.o. Virus is why scoutboy74 was asking for ya to post photos of the diff cover it self. That tells the tail of what the axle is. There is a distinct diference in shape in the cover between the Dana 44 and Dana 30.
 
Yeah, '74 was a transition year with respect to the sii front driving axle. I've heard tell of instances of owners who've acquired '74 scouts with disk brake d30 fronts, same as some who've had '74 scouts with d44 front drum brakes, but those are rare in both cases. Most in stock form rolled with either a d30 and drums (early-mid '74) or d44 and disks (mid-late '74). All '75 and later 4x4 models came with d44 fronts and disc brakes.
That's just a continuation of the fyi. The front axle in question is almost certainly original to the vehicle, with the original drum hardware removed by a previous owner in favor of disc brake components. Sure, it could be one of those original basterdized '74 units swapped in as a whole assembly by a po, but I think that is unlikely. Why go to the trouble of swapping one d30 front for another? Just for disk brakes? Nah, not good enough. The overwhelming majority of Scout front axle swaps involve going from d30 to d44. The more robust axle assembly in addition to the disk brakes makes it worthwhile.
 
I'm one of those few who has a 74 with a Dana 30 with disc, that came factory. But swaped it out in favor of the Dana 44
 
My '74 had d30 and disk brakes too. The axle in the pic 49 sure looks like a d44 to me. I thought the spring pad was on the axle tube on a d30. My d30 went away about 20 years ago so the memory is a bit vague. Oops, looked at it again and the mount is on the tube so it is a d30.

Two lucky winners. Nope, its d30 all the way. The housing/diff cover is the dead giveaway. With the 30, it is more of an oblong oval shape. With the 44 it is closer to being a uniform circle.
 
Just out of curiostiy how much does a front end Dana 44 with at least 3.73 going for (new and old)? Complete from hub to hub?

Click to expand...

From a wrecking yard or off Craig's list or here in the forums, a minimum of 250 if you're lucky. I have seen used ones go for as high as 500. New, you're looking at least twice to triple that price.
 
I am in ventura county, does anyone have a front end d44 complete hub to hub worth selling (at least 3.73 gears)?

So the plot thickens, at least in my novice brain.

I actually looked at the two hubs, when I took off the outer hubs I just put them on the side and did not give them the proper attention.

The driver side hub is one single unit with the assembly on the shaft. The passenger side is actually two pieces and the assembly is still in the middle piece. What I mean by two pieces is there is the outer hub and another seperate metal piece between the outer hub and the rotor, which is where the assembly is.

I will get some pics out in the next few days for the visual. I am new to all of this and it just seems very odd to have this be normal.
