    I was recently sold a 85 Blazer Chassis with 1977 1 ton axles. The guy swore they were original axles off a 1977 Chevy 1 ton truck. This would mean that there was a D60 up front and a GM 14 bolt bringing up the rear. I had no reason not to believe him, so I took his word for it and bought the chassis for $550. This would have been a good deal even if it wasnt a D60 front, because everything was reworked, blasted, and painted, but that axle was an added bonus. Now heres the [censored] part of the deal. I have had the chassis a few weeks now and a buddy came over and doubted it being a D60 - he thought it looked small. We measured the circumference of the axle tubes on the chassis and then on the D44 on my truck. They both measured 9 1/2 inches. I then looked at the axle ID on this site and measured my ring gear. Mine measures 9" in diameter. Now, is that a 8 1/2" D44 or a 9 3/4" D60? Please help.

    Thanks for all the help guys -
    Derek

    The easiest way that I know of to identify the axle as a D60 is to check whether or not it has "kingpins". If it does, you will have grease zerks on the top and bottom of each knuckle. Also, on the passenger's side spring pad, the spring will have one u-bolt around the axle tube and 2 bolts into the diff housing itself, not 2 u-bolts like a D44. Hope this helped!

    There should be a number cast into the web near the pumkin. On a 44 the number would be 44 (duh) and on the 60 (you guessed) 60. The cover shape is the same the D60 cover is just bigger. Hope that helps. I just measured my D44, the overall height of the pumkin is about 10.5", If yours is considerably bigger than this its probably a D60. Also the two bolts on the sides that are vertical are 3.5" apart on the D 44, and I know they are farther apart on the D60.

    Damn, Damn, Damn... I have a castle nut, no grease zerks, two u-botls on the passenger side and the differential measures 10.5". Looks like I struck out. That sucks... Was supposed to be a D60.

    Thanks again,
    Derek

    That looks like a D60 to me. Look at the steering arm on that pic, it had (4) bolts in a square. I would have to say that, that is a D60!

    The guy must have used 3/4 ton axles, not 1 ton.

    Now you will always know what a D60 doesn't look like! So many people think they have 60's. I see ads in the local paper all the time. "One ton front axle - $150 OBO" yeah right.

    You got the running gear from a 3/4 ton truck. The 1 ton rear axle has the spring pads in a different place, so it wouldn't fit under a Blazer. The 44 you have is (I think) the HD version, which is fine unless you plan to duplicate Quagmyre. I ran a 1/2 ton 44 under my Blazer with a 454 and 33s in some hellacious rocks, and I blew a Warn Premium hub rather than damage the front axle. Stop worrying and start building.

    Little Pig, what is your definition of a HD 44? I see this term floating around...

    I am not being an ass or picking on you, i am just wondering.

    As I understand it, the HD had 8-bolt hubs, and possibly heavier wheel bearings, ball joints etc. (not too sure about that). It may also use a heavier U-joint. The main thing is that you have the 8-bolt rather than 6 bolt hubs.

    Please dont take this as me picking on you, because I am not. I see a bunch of people saying HD44 and I just happened to ask you, please no offense...

    I have an 8lug 44 in my Jimmy that I swapped in and the Ball joints, ujoints, bearings and all are al lthe same a s a 10 bolt. The only difference that I came acroos are the 8 lug wheel pattern and large lock outs.
    Other than that, all the part numbers are the same for the 10 bolt.

    There is no such thing as a HD Dana(Spicer) 44. It must be a slang(sp) term for 8 lug rotors and hub.
    Please someone prove me wrong.
    With verifiable source in writting.
    TIA

    What you say is correct about the bearings, but Dana(Spicer) is the maker of the 44 and they do not make a
    HD version. If Ford/Chevy/Dogde whats to give it a HD name in there sales/shop manuels so be it.

    Ok answer me this is there a 10 bolt axle that resembles the octagon style 44 or are they all semi rounded? I am trying my best to find out what is under my k5 and there are no markings on my axle for whatever reason. I can say that it doesn't resemble the 10 bolt axles on the id chart but it does resemble the 44 but why does it not have any markings?
