questions regarding full width 1 tons
I'm sure I'll have more questions as I go a long and my head is swelling from all the reading I have been doing. Long story short I was going to build up a real good d30/8.8 combo but after pricing everything I can actually just put a set of full width 1 tons under her that are already built. The plus side to this also is not only are they already built but I get 2 sets of tires with em as well. Anyway, they are Dana 60's out of a 80 ford. The owner of them was going to link em so shaved off all mounts, and the front is set up with full hydo, however with the way its setup it would interfere with the leaf springs. My immediate questions are with having to weld all new mounts on, is out boarding the springs necessary? Or what would be a good way to go about it? I've never messed with a hydro system but can I remove all of it to go back to a tie rod and drag link setup, just by removing everything? And I have yet to actually read into it but what do I do about driveshafts? Thanks and this should be a fun endeavor.

Give me a minute & I'll post a link to my front '88 - '91.5 Ford F350 kingpin HPD60 swap thread. I ended up doing a homebrew spring outboard on it.

Do you have pics of the front axle so we can see where the full hydro stuff is located?

Joe Dillard 09-09-2013 09:57 PM

Here ya' go:

If the front 60 has the shorter ~3" axle tube on the driver side (as compared to the '78 - '79 Ford which is ~7") you'll have some challenges ahead of you.

Having only ~3" of axle tube on the drivers side to deal with makes things tough as compared to 7" ESPECIALLY if going with links.

On the other hand - with the HPD60 that has ~3" of axle tube on the driver side, outboarding and stock type exhaust clearance is better.

Note how well the shaft is positioned between the framerail & exhaust going to the Atlas. If it were a 78/79 axle, things would be different and I *could* have exhaust issues (some do).

Figure out what you have for an axle first, the front. Ford never ran a 60 front in 1980, they did in 77.5-79 then they picked them up in late 85.

Yes even in the F-350 during those bastard years got the TTB50,
ask your self how many 80-84 F-350's did or do you see none, they never took off like Chevy or Dodge did.

So like Joe was pointing out, you might have a late 80's axle that will need to have the springs outboard on the frame, these newer year axles will have NON neck down shafts and larger 9/16" lug nuts and a very short side tube.

The 77.8-79 ( or commonly called the 78-79 ) will be a bolt in for a YJ, but have factory neck down shafts and smaller 1/2" studs. what ever axle you have its a great start.

Now for the rear, ford never used a 60 rear in there 4x4 trucks during the 80's, 70's yes but not as commen as the sterling 10.25. The 78-79 used them in F-250's and the F-350 got the 70, in fact that's the only difference from the 250 to the 350 and one extra leaf spring in the rear from all the trucks ive seen go threw my yard.
But the front 60 stayed the same and even some snow fighters I had they had 3.55's but all the camper specials all had 4.10 that ive seen.

Rear is not as important to figure out as a front other than if its a small bearing rear 60 with wimpy 1 3/8" shafts, but what ever 60 front your golden.
Welcome to piece of mind:thumbsup:

cant really tell from that pic, but to me from this angle the front looks like a newer 88 SRW. I am loving those solid one piece steering arms. That's giving some huge ideas for my next build.


Unclejimbo 09-10-2013 05:10 PM

Hah glad I can help with that :) so looks like I'll definitely be out boarding the springs.

jason m 09-10-2013 06:47 PM

Another quick way to tell is just measure the center to center of the spring perches, if it measures 36" then its a newer axle, 27.5" then its a 78-79.

78 front,

86 front that the long side tube was cut, but look at the short side tube and compare it to the 78, its a lot shorter and like I said the perch centers will be 36"s.

A few shot of my 79 D60 with hydro assist in my 92 YJ. No interference issues.

Unclejimbo 09-10-2013 08:08 PM

I would but the perches have all been removed.

Unclejimbo 09-10-2013 08:10 PM

I like all y'alls work very nice

squarelite 09-10-2013 09:58 PM

You can route the exhaust in front on the oil pan. My father in laws yj is setup that way. He has an atlas II with a built 78 hp 44.

Yes but there still might be some grind marks, that will at least indicate a general perch spot and your cast spring perch is still there. its around 9"s difference between the two axles spring perches you should be able to tell the difference.


Unclejimbo 09-10-2013 10:10 PM

I will check when I go to pick em up, and I'm sure by then I'll have more questions.

The time now is 02:06 PM.
