Driveshaft phasing on 2008 Prerunner?

Last night I removed the driveshaft on my 2008 Pre-Runner and replaced the carrier bearing and all the u-joints. I made sure to mark the driveshaft to the transmission and the rear diff so it would be aligned properly when I re-installed it, BUT unfortunately I forgot to mark the center yoke orientation before pounded out the u-joint. Though I didn't mark how the two piece driveshaft connects to itself, I was able to extrapolate from my other marks how it fit together.

From what I understand, most driveshafts are phased correctly when the yokes from each piece are aligned in tandem like this:


But based on the markings I made at the transmission and rear diff, I needed to reinstall the front end of the driveshaft with the center yoke spline rotated 90° like in this diagram:

I went ahead and re-installed the center yoke at 90°, so my other marks lined up correctly. I assume it is fine because the truck runs great and there isn't any vibration. I'm kind of confused about the correct yoke orientation because I've seen diagrams and photos of the same shaft with yokes installed in both orientations.

Does the center yoke orientation (after the carrier bearing) really matter as long as the transmission (input) and pinion (output) angles are identical?

Yes i'll mark everything properly next time.


For reference the driveshaft is:
Toyota part# 371000435000
Spicer part #5002350-4

 

^If you do a Google image search of the Toyota P/N, photos of used OEM driveshaft suggest your center yoke is not clocked correctly. Ref: https://ahparts.com/buy-used/2005-t...idotj7-bHLtt3WYcKe8_co6qfV4f_EL15V7DA6jyFatrJ

 

Right, but the above schematic suggests that it is correct. I've seen it both ways and I'm wondering if there are any educated thoughts on this that go above and beyond the standard Google image search.

Fairy sure it must've come from the factory like this, because nobody has ever changed the carrier bearing before

 

^Driveshaftpower.com is a 3rd-party site, and the diagram looks more like a logo. I'd trust a photo of an OEM driveshaft over that. But if the driveshaft isn't giving you vibrations, leave it as-is at your discretion even if it's wrong I suspect the angle between the transmission and the carrier bearing is shallow enough for it not to show symptoms.

 

I suspect you're probably right that there isn't much of an angle between the transmission and the carrier bearing, so it probably doesn't matter.

This diagram is straight from toyota parts Canada showing the yoke mounted 90°:

In our Tacos with two piece driveshafts, I believe phasing is only an issue if you separate the slip yoke from the long piece - that has the rubber boot.

I have replaced my ujoints twice without marking anything and have never had vibrations. But I have never separated the long piece from the slip joint.

 

^No slip yoke with PreRunner. There's a sleeve yoke that plunges in and out of the rear of the transmission with suspension movement.

 

The parts catalog conflicts with the service manual, which means the parts catalog is graphically wrong, as it often is. Toyota's parts catalog is contracted to a 3rd party that also does parts catalogs for other automakers. A couple of years ago they had a Jeep Compass grille as a picture for the 2020+ Tacoma grille. The 1GR bank1 VVTi spool valve is shown as a pancake-style VVT solenoid for the Ford Coyote V8, because

Update:

I made more marks than I needed to and mixed it up. The driveshaft yokes should be "in phase"
