Dana 60, 10b\'s, d44\'s and a thanks

What did the Dana 60 come in? And how do the 10b fronts compare to the Dana 44? I'm pretty sure Dana basically made the 10 bolt but i'm not sure what part of it is weaker than the 44. Just want to say this board is the most resourceful tool for finding out any info or questions i have on my K5. Thanks to all you guys/gals for sharing all your knowledge with the less experienced, with these awesome trucks, like myself. Go figure - I bought my K5 about 2 months ago without many major plans, now i'm getting ready to slap 35's, lift and a 14bff and a D60 under her. And i contribute all those decisions i'm making to build her stonger to you guys! Ahhhh, how the madness just slips in when you're not lookin'

Thanks for all the help, past and present.

The Dana 60 came in the 77-91 K30's.
Dana 44 and 10 bolt are near identical strength wise and the 10 bolt was not made by 'Dana'.

Good luck with all yer mods!

Thanks Rene. I guess the info i read and heard on the 10b &amp; 'Dana' was incorrect. sorry. Appreciate the quick response.

Re: Dana 60, 10b\'s, d44\'s and a thanks

You may have heard that both the corporate axle and a Dana 44 axle have 10 bolts to hold the differential cover on (I believe D 60's too), and that sometimes causes confusion. The corporate (GM) axle is called the 10 bolt while the Dana's are called 44's and 60's, even though they all have 10 bolt covers. Confusing isn't it. The most common mistake is between the D44 and 10 bolt because they are approximately the same size and design (ball jointed with 4 u-bolts, 3 one size and 1 another). The covers are the easiest way to distinquish between the two. The corporate 10 bolt is fairly round, while the D 44 has been described as a monkey's head tilted sideways. The D60 is pretty easy to spot due to it's larger size, king-pins instead of ball-joints, and 3 u-bolts and 2 bolts to hold the springs to the axle.

Hope this helps.
P.S. if any of this is incorrect, please let me know.

Re: Dana 60, 10b\'s, d44\'s and a thanks

What i've heard was that 'dana' actually made the corporate 10b and the two were very near strength except for.....axle diameter..or...not really sure. Guess that info was wrong and thanks to you guys setting me right. Not confusing when i get the right info. I'm also assuming (i know, never assume) that the 44 would be easy, or easier, to swap in, pretty much a straight bolt in compared to a D60? Or maybe they're just as easy. It helps a lot with the info you gave. Thanks.

Re: Dana 60, 10b\'s, d44\'s and a thanks

10 bolt and D44 will pretty well interchange, I haven't swapped in a D60 yet but I've heard they go in with little or no modification...

There are some axle shaft differences between the D44 and the 10 bolts...D44 are 30 spline. The 10 bolt came in 28 spline and 30 spline in the later years (89 and up i think). The inner axle shafts are also slightly different lengths between the 10 and the 44. The 30 spline 10 bolt is prolly a bit stronger than the 28 spline version, although it's usually the axle u-joint that fails first. The disadvantage to the 30 spline 10 bolt is finding spare axle shafts for it.

Re: Dana 60, 10b\'s, d44\'s and a thanks

In a K5, a 10 bolt or D44 is direct bolt in. The only issue is brake lines (If I remember correctly the "banjo" bolt that is used to secure the brake line to caliper is different between the 10 bolt and D44), so you may have to get another set of lines from the frame to the caliper depending on which axle you choose. A D60 is a bolt in but it requires new u-bolt and bolts, a different steering arm (if not already equipped), (it shares the same banjo bolt as a 10 bolt so brake lines MAY be needed), and new spring caps (the pieces that go on top of the spring pack that hold the spring in place and the sway bar bolts to). This is assuming a stock height. With a lift a raised steering arm/dropped drag link may be needed as well. Hope this helps.

Re: Dana 60, 10b\'s, d44\'s and a thanks

I have heard that Dana/Spicer builds the 10 bolt axles for GM and labels them as the 'corporate' symbol.

I have not heard of any other axle manufacturer that makes the GM axles other than Dana/Spicer.

Re: Dana 60, 10b\'s, d44\'s and a thanks

Didn't know who to reply to, but thanks t, K30 and Leadfoot. So basically, it's just as easy to bolt up either a 44 or 60. I'm looking to get a 14bff w/4.56 and i was just considering my options with my stock front 10b w/3.42's. I haven't wheeled real hard in the last couple of years (family in the process of growing, hehe) but that doesn't mean in a year or two i wont be taking my son and teaching him the fun

and i want to build it once if i can. I'm not going to touch on the 'Dana' vs 10b corperate subject anymore, but i get the jist of it. Dont want to see fellow CK5 members in a heated battle

Thanks for all the info guys. Really helps and points me in the right direction, as always.

Re: Dana 60, 10b\'s, d44\'s and a thanks

Wes, do you know if Dana was always part of Spicer? I think I heard rumor (way back) that Dana produced their own axle, so did spicer (who mainly sold to GM as far as light duty pickups went). Both were used on GM's (the whole corp. vs. Dana deal). Then at one point they merged as one company Dana/Spicer and pretty much make both axles still under one trade name. I don't know if there is any truth in that, but wanted to know if you or anyone else had heard it.

Re: Dana 60, 10b\'s, d44\'s and a thanks

No heated debate...but I do remember someone that worked for Dana Spicer saying the 10 bolt was not a Dana/Spicer product. It doesn't really matter in the overall scheme of things...

Re: Dana 60, 10b\'s, d44\'s and a thanks

The only thing that matters in the scheme of things is: Where to find a Dana60 for less than a left testicle or an arm and a leg?

Re: Dana 60, 10b\'s, d44\'s and a thanks

Yeah, but even if you find one cheap, you still may lose a left testical trying to lift the damn thing

!

And there are very few heated debates on here. I think sometimes posts are misunderstood because of the way it looks on screen, it would be a whole lot different if these "debates" were face to face or via phone. That's why I try to throw in a

or two. After I re-read some of my posts, it doesn't look/sound like the way I meant it (sometimes it sounds pretty bad even when I don't mean to), so I try to be careful (doesn't always work though

).

One thing for sure though, there may be alot of differing opinions, but there is also alot of expertice and knowledge on this board (one of the reasons this site kicks butt). If you watch long enough you know who to contact or ask for certain questions. Case in point would be ThatK30Guy (Wes) due to the amount of K30's he's had and seen, plus I believe he has researched some facts (like what year K30's started and what types of drivetrains you will find in which year), and TrustyK5 (Rene) when it comes to welding. There are too many people here to list what each is knowledgeable in, but they are out there.

Spicer was founded around 1919, by Joe Spicer, they are most famuos for the Time Tempered U-Joint !
They became part of Dana around 1949, and to this day they are part of Corp. Dana !
The Corp. 10 Bolt as in GM Corp. not Dana Corp. came out around 1977, and Dana(Spicer) did not make the
GM Corp. 10 Bolt, Dana(Spicer) did not assemble the GM Corp. 10 Bolt.

Re: Dana 60, 10b\'s, d44\'s and a thanks

So what you are saying is GM has their own tooling to make the "10 bolt", 12 bolt, 14 bolts, etc. without an outside source such as Dana or Spicer, or do they contract out to somebody else? Just wondering since we are on this topic.

Re: Dana 60, 10b\'s, d44\'s and a thanks

Oh well, got me here!

I could swear I either saw, read, or heard that D/S was responsible for making the Corp. axles.

The way I heard it, (if I remember right

) was that GM hired D/S to build the GM 'designed' axles, therefore the Corporate 10, 12, 14, etc. were made.

Another thing to ponder: if you notice the axle shafts in nearly all the Corp. axles, they have 'Spicer' stamped on them. I don't know if GM has the Spicer shafts for their own axles, or what. U-joints are the same thing.

Oh well, I just wanted to let everyone know what I had heard, seen, or read somewhere.

Re: Dana 60, 10b\'s, d44\'s and a thanks

When I toured the GM Factory in Van Nyes CA. the GM 10 bolt was stacked to the roof, and the train box car
they were unloading came from.............. Eaton............
So I guess at that time they contracted out to Eaton for 12,000 GM 10 Bolts for sports cars !
Not sure about the other axles(12, 14, at that time)
I have also be to the Arlington TX. Assembly plant, and saw no axles being make, only installed in Trucks.

Re: Dana 60, 10b\'s, d44\'s and a thanks

Now that makes more sense!!! From Eaton!!! Now, that one I can believe.
