    I have a '79 GMC 1/2 ton High Sierra pickup and I cant fiqure out what front axel I have. It looks similar to a D44 but my front cover and housing are larger. The yoke is larger than a D44 also. My local GM dealership didnt even know what axel it was.
    Does anyone know what I have or how I can find out?


    Thanks,

    -Lane

    ASSuming it is original, it would be a Corporate 10 bolt. Very similar in size and strength to the D44. Each is available in six or eight lug and both are swapable from the knuckles out.

    Can you post a pick of it?

    I dont believe it is a GM 10bolt. It has a bolt patter like d44 and not round like Gm 10. It has 6 bolt hubs. 3bolt steering arm. Are there numbers that Identify it or something? It not listed in the Axel ID chart.

    I'll see it I can hook up with a scanner and post a pict sometime

    Sounds like a D44...with the 3 bolt steering arm it's going to be either a 10 bolt or a D44.

    <font color="green"> You're going to have to post a pic. The only axle aside from the 44 and 10 bolt that came in Chevy trucks was the Dana 60, and that was only 8 lug and did not have the steering arm that is held on with 3 bolts. So it's something weird, unless it's just a Dana 44 that you're confused about. You wouldn't be the first guy to think that his D44 was something else. /forums/images/graemlins/thumb.gif

    Maybe it's a 12 bolt. /forums/images/graemlins/rotfl.gif</font>

    the axle guide doesn't include front axles. Have you actually seen a front axle Dana 44 that you know its so different?

    Just the cover shape of the D44 versus the 10 bolt is enough. A front D44 has the exact cover pictured in the axle guide...
