    My question to all of you is on D44/10b front spindles, 1/2ton vs. 3/4ton, 6lug vs. 8lug, what if any difference is there? I have been under the assumtion that they are the same, but that idea has been questioned a few times on CK5 so I though I'd open it up to comment. I have both axle around and will pull them apart as soon as I get time to check out any suggested differences. Thanks, RDRAGE/Brent

    I have installed a D44 6-lug spindle on my 8-lug D44 and it worked fine. Not sure about the 10 bolt stuff, but I've heard it's the same.

    1/2 and 3/4 ton spindles are the same starting in 1977 when they made a change in the outer bearing diameter. and 10 bolt and Dana 44 are also the same

    <blockquote><font class="small">In reply to:</font><hr>

    Spindles. 73-76 are one type only. They are "first design" small bearings. 1/2 and 3/4 ton spindles are interchangable. 77-91 spindles are "second design" and all interchangable between 1/2 and 3/4 tons. You cannot use a first design spindle with a second design bearing hub &amp; rotor. The hub will wobble in place. If the second design spindle is used with a first design bearing hub, the hub will not even go on at all.

    I did some more digging today and found the same as what ThatK30Guy says (Thanks Esteban86K5). The only slight difference from that is that there are two bearings shown in the Timken catalog for pre 77 3/4tons, a heavy duty and light duty.

    Is an external hub dana 44 3/4 ton spindle different than the 1/2 ton spindle? These are usually off older trucks, and I heard the hubs are a little different in size?...is that right?
