    well i cant afford to install my D60 right now, but my D44 is pulled so i might as well rebuild it befor i reinstall it. so here's my question i understand spicer makes more than one u-joint for a D44. the old ones are part#5-297x and the newer stronger ones are 5-760x, is this correct? so if this is correct the 5-760x's are direct swap from 5-297x's right? i just wanna make sure i order the right part. thanks /forums/images/graemlins/grin.gif

    You can't afford to install the d60?
    It's pretty much a bolt-in.
    Rather than sink money into the 3/4 front, spend that same amount on the d60.
    Seriously, what's wrong with the d60?

    Yes, you are correct.

    The 5-260x was replaced with the 5-297x and finally the stronger 5-760x.

    They will cost a buck or 2 more than the 297x's.

    there's a whole lot more to installing a 60 than just bolting it in. where should i start.

    35 spline hub/stubs/ujoints $300
    5- 39" swampers $1200
    5 hummer wheels (custom backspacing) $164 each
    cross over steering and rock rod $800+-
    locker for the 60 $400-$600.
    so the total is at least $3500

    yeah i could just put it in with out alot of that stuff but 4.56 gears and weenie 31" at's don't mix very well so now were talking about $1500 to get running with some 39's and cheep wheels. plus i gotta buy hubs so i might as well go strait to 35's so add another $300 to that $1800. so as you can see there's alot more than JUST BOLTING IT IN. /forums/images/graemlins/eek.gif

    Are you sure?
    I ordered mine from NAPA, and when I got the first set it was the 260x, wrong dimensions, then I got the 760x, wrong dimensions.
    I don't think they interchange. They changed the axles to go with the newer stronger U joints. Someone corect me if I am wrong?
    The 297x is 3" the 260 and the 760 came 3.5"
    and the cap sizes, 260 = 1" 297 = 1&amp;1/8" 760 = 1&amp;1/4"
    Anybody expert on those U joints, because now I am affraid to go back to the place the guy is so frustrated I think he will kill me if he knows I retuned them and they were good. /forums/images/graemlins/confused.gif

    imiceman44: I think your counter guy doesn't know what he's talking about. I HAD the 297's and replaced them with the 5-760's. They are a direct replacement for the 297's.

    30-spline outers are stronger than the d44 front you have. Just run them for now.

    You can run 15" wheels with a d60.

    It's more expensive to do that to a d44.

    Cost is the same for a d44.



    I don't know, I just still can't see spending money on the 3/4 front if you already have a d60 just sitting there.
    To each his own.

    You misread the posts.
    the query was in regards to the 260 being equal to the 297.
    which they are most definately NOT the same size

    Waxer, it's not the counter guy.
    I measured my 297x, and then he got me the 260x I measured and told him no.
    Then he looked it up again, and he said 760x is the new replacement for the 297x, and he ordered them, I measured, and told him no.
    I see on ORD they are advertizing the 297x, wouldn't you think they would offer the 760x instead if it was the same size?
    I am sure that the 760x is stronger I saw it it's bigger, but it won't fit. I am sure the newer axles are made for them.
    Again if I am wrong some one correct me.

    I dont think so, there was no query. He was stating sizes on the 3 diff ujoints and I know for a fact that the 297's and 760's interchange. His post does not agree with that.

    imiceman44: you are wrong on them not being the same cup size. Like I said, I replaced my old 297's in my 1974 D44 with the new 760's. They fit perfectly. I don't know what the counter guy brought out to you but I think you should definitely give Jess and High Angle Driveline a call as he's the one I ordered my 5-760x's from.

    I was going all the way back to Goober where he stated the 260 = 297 = 760.

    I agree that the 760 = 297 and is a direct replacement

    Well the parts were Spicer parts and the number was correct.
    Can my axle U joint be different? Can you give me measurements to compare?
    Diameter of cup and length of joint from edge to edge?
    Thank you

    Yes it sounds like you have something else then. If you take the 297 and 760 and look at them side by side, the only visual diff is the cross looks beefier somewhat on the 760x. Then if you take the caps off and look there, you'll see a size diff between the two.

    The 297's are being phased out with the 5-760x's being their direct replacement. The 297's you buy now are whats left over as they arent made anymore. Dont you think companies will want to get rid of that obsolete ujoint first before advertising its replacement? Otherwise they are stuck with them.

    OK I am taking my U joint out tomorrow and checking again on my measurements but I could swear that the cup size is 1&amp;1/8" and the cross is 3" edge to edge. Anyone know what number this one would be?
    My blazer is 76 so it could be not the original, but it's a D44.
    Any help please.

    well what did i get in the mail today, my new issue of fourwheeler and they just happen to review the new 760's. i guess this post was one day early. /forums/images/graemlins/grin.gif

    They cost the same if you bolt them to a d44.

    how said i was gonna put 39's on my d44

    You can run 15" wheels with a d60.



    [/ QUOTE ] thats great but thats still $300 i don't have along with the $1200 for tires i also don't have

    [/ QUOTE ] once again who said i was gonna put a locker in my 44
    all i wanna do is fix up my 44 a lil so i can wheel it for another 8 months untill i can come up with another $3500 to install d60 that as you say is just a bolt in application. well this might very well just be a bolt in axle but what about all the other stuff that goes along with it? such as wheels, tires, cross over, hubs, locker. that at this pressent i do not own nor do i have the cash to buy.next time don't assume things and don't put words in my mouth

    [/ QUOTE ]

    You are right, I was wrong: The 260x has a bearing cap that is 1 1/16" and the 297x - 760x is 1 3/16".

    The 760x has been out for a few years now and Dana says that they are much stronger. I haven't tried them but they look like the old cheezy Neapco u-joints.

    Here is a picture of both:

    I know for a fact that the 297x is strong enough to bust an axle so I would just stick with whith those until they are out of stock, you might save a few bucks.
