I got a spare drive line with my recent caddy acquirement. It has a double carden(CV) joint at both ends of the drive line. Why did they do that? Would it be worth it to try and use it for something tuck related?

Why did cadillac use double, double carden joints on their drive lines?

- Start date
As far as I can tell the only reason they did that was to further dampen vibration as much as possible. Silky smooth ride....
I don't believe that joint is rebuildable. We looked into purchasing some of those parts back in the day when we made a few driveshafts and couldn't find much.

I didnt think that was possible without supporting the center of the shaft. If you had two cardan joints one on each end of a driveshaft the shaft would just flop around.
my s10 has one of those joints and because there's no angle on them, it seized up and needed to be replaced with a regular single joint @ 70k. Thanks GM
Nope, it works.

Yup, not rebuidable. And a pain in the arse to find. One car I did recently was find an old oldsmobile and have the joints swapped over the the caddy shaft. What a pain.

What makes them not rebuild able?
I don't think my s10 was either

Not 100% sure bit our local driveline shop won't touch them. They have done many many shafts for our shop.
The Chevy truck ones and fords no problem, but something about the Cadillac and GM big car stuff

Wo wth! I still dont get how it works. It must be the spring loaded ball that keeps it from flopping like I'm thinking?

Yep. crazy stuff.
Picking my mind on how u joint drive shafts work, for ours to run smooth, the top and bottom (axle to shaft and shaft to xfer case) angles have to be the same.
With the double cardigan, im not sure it would matter.

After some research it appears to have the same spline count as a np241 output and is about the same length as the one in the burb.
i had mine rebuilt a few times, they came from caddys with the th400. it was a 1350 cv shaft and i added a full spline slip at driveshaftsunlimited here in town.
you take the slip part for your blazer and weld a 1350 weld yoke to the other side and viola! cv shaft for your new 14 bolt swap.
then the other side is a replacment for the cv flange at the front output.
we use em all the time. not sure why theyre "not rebuildable"

Those were used to keep the drivetrain from having any vibrations and also if there because alot of those cars had a pretty straight shot to the diff which means little to no working angle and that will eat regular u-joints quickly. A double Carden joint will work with no working angle. They ARE rebuildable, i've rebuilt my fair share of them in the last 23 years. When the center "cage" is bad my local driveline shop carries them in spicer brand.
