Doing some research. Thought this would make a good notepad and folks can all share what they know.

https://www.dennysdriveshaft.com/p1...ion_yoke_24_spline_1350_series_fits_2007.html

Won't work. Nissan uses involute splines instead of standard cut. So for now our only option is the Frontier/Titan 1310 series companion flange for the Nissan style splines. Still 24 spline.

Frontiers have tube yokes and companion yokes for 1330. Pathfinders seem to have 1350 and Titan has 1410 stuff. So we have options there.

So to elaborate, I'm looking to do away with the rear flange. The link there is for a 1350 yoke for the 24 spline Jeep M226. I'm waiting to hear back from Denny's on compatability since I'm having a hard time finding comparable specs on the Nissan flange.

If this works, I'm going to grab a Titan driveshaft since it has the proper 1350 yoke for the t-case and have it shortened to work in the Xterra with the rear yoke.

I would be happy to find a 1330 yoke as the 1350 and 1330 are the same width but the bigger caps on the 1350 give up operational angle. But I may have to just play with what I can find.

This all may be for nothing, but at least some of the info will be out there if I can find it.

I did some reading and it looks like the JK yoke I found will not work.

Nissan had involute splines put on the pinion of their gear sets and the JK/JL use standard splines. So that is out....

However, from what I've found so far, the early Titans used 1410 joints in their rear shaft and use the same pinion flange as the Frontier which uses 1330. The 1410 SHOULD have a lot more operational angle because of the much wider cross. And from what I have found the Titan uses the same t-case as the Frontier and Xterra so the slip yoke should work.

Back to digging....

For those of us who are ignorant about driveshafts but like to learn things, can you explain what you're wanting to accomplish by modifying this?

Stronger parts? Easier to field repair? More capability? Something else?

It also looks like the Pathfinders got 1350 joints in their drive shafts.

So there are 1330, 1350 and 1410 slip yokes out there for our rigs as well as companion flanges for all 3 joint sizes in various vehicles but they all mate to the Spicer 1310 companion flange that fits our 24 spline M226 rear axles (part # listed for Frontier, Pathfinder and Titan on Spicer website).

Man.... If they'd have just thrown a fixed yoke on our t-case this would open up a whole world of driveline possibilities but I can't seem to find a fixed yoke with the proper splines for our t-case output to attempt a hack-n-tap style SYE for our rigs.

In short, yes to all.

So a slip yoke on the transmission like we have gets weird at high angles (lifted vehicles). They apply force at odd angles under hard load where the slip splines may not actually slip like they are supposed to as the rear suspension articulates. You are also very limited on the amount of slip available.

Most hard-core offroad cases (NP205, D300, ATLAS, ect) use a fixed rear yoke and move the slip to the driveshaft. This keeps the forces aligned with the splines so that most of the pressure is applied along the log edge of the splines. This helps prevent binding under high load such as off-roading. You can also get shafts with extra long slip sections to allow for much more articulation without fear of pulling the slip yoke apart.

They also generally use a double-cardan joint (incorrectly called a CV most of the time) at the t-case output to allow higher angle operation than a single u-joint will provide. In that situation, you just pitch the pinion up to just below parallel to the output (to allow pinion rise during acceleration/loading) and the vibrations are usually completely removed from the system.

Lastly, these parts are all readily available on parts store shelves across the country. If you waste a u-joint, you just walk in and grab one from whatever parts shop you can find. Also, the double-cardan assemblies are pretty stock standard parts so you can usually source them from a junk yard in a worse case scenario. For instance, we use a 1330 u-joint at the t-case end of our rear drive shaft. If it was a 1330 based double-cardan, the rear drive shaft from most Ford trucks from 1975-1980 use the same assembly so you could just swing by a junk yard and grab those pieces to try to get yours going again. 1350 is even better since Ford uses them in the front shaft of the Super Duty trucks up to like 2010-2011. The only limiting factor would be a flange or yoke failure on the t-case or differential.

However, we don't have that right now. We have a Nissan specific slip yoke, Xterra specific CV at the rear diff and Nissan specific pinion splines on our rear axle gear sets which make it exceedingly hard to source pieces to convert to the much more desirable rear driveline setups....

I was hoping to find a fixed yoke that matched our t-case output splines, even if I had to source a custom seal, but would allow me to use a double cardan joint in a Hack-n-Tap style Slip Yoke Eliminator (SYE). But there doesn't seem to be anyone who makes such a thing.

So now the search continues, looking for options other than a fully custom made flange which is $$$$.

The easy, but not less $$$ route is to do what I have..... Tom Woods Rear Flange adapter, and their double cardan DS.

You just have to send them the Slip yoke and the flange to output shaft measurements.

I don't think they offer that anymore. It's off their website and lots of rumors floating around.

titan slip yoke works in our transfer case (1350)
https://www.dennysdriveshaft.com/p3...x_slip_yoke_1350_series_fits_2004_2005_2.html

Also, full compression to full droop, ours only moves like 1/4" (pushes in at full droop). I measured mine one time and was surprised it didn't move more than it did.

Also, you can get a 1350 pinion yoke for a jk that works.

If I had time and did this all over again, putting the frontier 4 bolt companion flange on the pinion and running the 1330 rear yoke with the stock 1330 slip yoke at the transfer case makes the most sense to me.

This!.... So much This.

And I can verify that slip yoke works, because that's what I bought to have Tom Wood's alter for my double Cardan DS they made.

I can't find the JK yoke with the proper splines. They are both 24 count but the spline shape is different per Nissan spec from Spicer's own literature.

From my findings, that site has the 1350 yoke labeled wrong. Xterra and Frontier have 1330. Pathfinder is 1350 and Titan is 1410.

But we all use the same t-case so the 32/34 output spline.

we use jk gears.... they work.
