How do you determine if its a D60
how do tell if it is a D60? I just saw a ad for a 77 F250 4x4 and it says D60, but my 76 F250 4x4 has the HD D44
so if I go look at it how do I tell?
Thanks....Rick

If you can compare the size of the cover to your 44 or to the rear 60. Should give you an idea of what is under it.
The best way is the BOM number or look for a 44 or 60 cast in the housing. If it is a later model 78-79 60 that has been swapped in, look for open knuckles disc brakes and kingpins.
A lot of guys see the large hub of the HD 44 and assume that it is a 60.

We all tend to forget the basics here. Many times an axle has been changed, and once in a while it can be for the better.
Not many folks would know that under my 74 rests a 79 D60 with 35 spline inners and outers. Niether the door code, nor the BOM would ever indicate this, and trying to identify the basics is really very simple.
D44's for this era will have ball joints, and D60's will have king pins. Because of the frame and spring pad width, it will not be common to find the later king pin (after 80), or ball joint 60 under the front of an early truck.
This actually goes a little further, because some may actually find a D60 closed knuckle front axle under a later truck, and everything gets confused. Disc brakes, drum brakes, king pins, ball joints, yada, yada.
There are two very distinct differences, and all it takes is two wrenches. One 9/16" box end, and one 1/2" box end.
The diff. cover bolts for the 60 takes the 9/16" wrench.
The diff. cover bolts for the 44 takes the 1/2" wrench.
Simple as that.

I don't have a Dana list on me either. My keen senses can spot a 78-79 D60 under waist high grass in a field at 60 mph. At night, no less.

According to my FTE research, which I could be wrong, but this is what I use.
1. Drivers side pitman arm to steering knuckle, D44 radius 3 bolts
2. Drivers side pitman arm to steering knuckle, D60 square 4 bolts
3. D44 10 bolt cover
4. D60 9 bolt cover
5. Look to the left side of diff cover on bottom of axel tube for stamped numbers and letters, might see 44, 44F, 446CF ='s heavy duty?
And if you are lucky the infamous 60, meaning you just found a gold mine. IMO
Also means no need to carry wrench
Also D60 has 4" outer hubs and D44 has 3.5" BUT someone could of put D60 outers on a D44 axle? Hope this helps, if I am wrong in any way, some one please correct me.

For reply# 4 above, it needs to be slightly corrected.
Dana 27, 28, 30, 44, 50, 60, 61, 70, and 80 all have 10 bolt covers. Only the D36-ICA (independant suspension) differential had other than 10 bolts, it had 8.
For reply # 2 above, it needs to be expanded. We cant forget that the early low pinion D60's had the same style steering, but are not very desireable.
Later model D60's have ball joints and do not have any provisions for that steering arm that attches to the top like a king pin unit.
For the last reply above, this also needs a little clarification. Later model D50's also have a large hub, and is often confused for a desireable unit, which it is not, and D44HD's had large hubs that are also often confused for D60's. Even early D44's with large hubs and an external hub design are large in diameter, and often mistaken for the D60.
Takes a little while, but identifying them gets easier and easier after you put a few in front of you.

75F350 thanks for the updated info. All the info I gave was located on this web site, looks like alot of people have alot of ways to ID a D60.
Yes, early D60 close knuckle not to desireable because 30 spline inners and 19 spline outers. Little U-joint, drum brakes, and a prone to leak outer axle seal?
Any way, thanks again for the help. Hope all this helps out rsalter66.

Yea, I'm cool, it looks like I am going to stick with what I got anyways, the truck is like an hour or so away, and when they finally got back to me they wanted more then I want to spend on one right now, they mentioned $600 for the whole truck, which aint bad, bad still more then I want to spend, ( They said because scrap prices are so high?) and then jacking around renting a trailer to bring it here?
not worth it for me. I had seen some around here but now they are gone too, probably off to the crusher, I went to one of my local junkyards where they usally have a lot of old stuff, but they only had a few old ford trucks and not much for parts that I want, its OK though, I'm fine with what I have and I know of a guy down in farm land that has a bunch of old fords sitting out back in a field and I'm going to talk to his girlfriend and see if I can go back and look at whats there (she is one HOT MILF) thanks for all the help guys, see ya....Rick
