This is a 14BFF in a 1/2 ton truck that had a 10bolt. Used napa Part number #447. 10 bolt to 14B conversion joint. Why is it not conversioning? Thanks

Problem with this? *pics*=UPDATE=

the joint looks a bit small............I usually have to tap it in with a hammer because its so tight.
If I was to tap it in with a hammer, wouldnt there be a lot of space under the strap? The only place that cap is really touching is at the top of the yoke on the picture.
The strap should be nice and snug. You need new straps.
so the joint is right? just the wrong straps? that would be cool! id hate to have to get another joint. I got the straps at napa too
Its hard to tell in the pic but it looks like a small joint, there should be no play at all around the cap.
suggestions on what to do then? I dont wanna go spend 20 bux on another 447 and have it be wrong again.
This is common and a weak piont with the factory GM straps. HAD drivline offers aftermarket yokes, which uses U-Bolts instaed of straps, as a cure for the weakness in the factory strap design.

I am in the middle of a 12bolt to 14bolt conversion got the new u-joint hope the straps I have work.......I also just read in Four Wheeler that Moroso makes a strap that works like the HAD ones but you may be able to pick those up local????

The straps don't appear to be mangled, in fact they look basically perfect. I'd say the joint is too small, the question is why. 447 should be the right joint. Measure the bearing cap diameter at each yoke and post up. Shouldn't be too hard to figure out.
It looks to me like it's not a 447 S44 to 1350 conversion. In fact, I'd say it was just a straight S44, or possible S44 to 1330 joint. Do you think it was in the wrong box?

Here's some reference info from another thread to compare with.

I dont think it coulda been the wrong box? I mean if i got the 12B joint wouldnt it not fit into the driveshaft? The driveshaft caps were bigger than the 14B caps i know that much
I'll go measure a bit later and post up my results
There was an article, I think on pirate 4X4 on this issue, about the weak pionts and confusing amount of different size factory straps. I think there are supposed to be 3 or 4 different size and style factory straps, which is why the article went into HAD's aftermarket yokes, which use U-bolts instead of straps to cure this problem. They also talked about the problem with the factory straps not mating completly around the u-joint caps, even when the straps are the correct ones.

Jesse, last time i checked doesnt offer 1350 w/ u bolts. besides milling a stock yoke to accept them greatly reduces the strength of the yoke...
The u joint appears to be too small, the straps may be right. Either way though, if the correct straps are used, (and new), and the joint is right it will be tight, it wont look like that.

inch and an 8th is what i get for a measurement on the cap of the U-joint that goes in the 14BFF yoke...
you can drill out the threads and get u-bolts if you dont want straps. I know a couple people who have done that with no problems.
