Well I'll be damned.... I knew that u-joints needed some angle, or a perfectly prescribed angle so the u-joint is actually rotating in itself (the little needle bearings in the cup are not allowed to stay in one spot cause they will wear In a groove in that spot after some time), but never knew about why exactly both u-joints needed to be the same angle, and definitely didn't know about the yoke phasing. Incredible. Thanks
So, if the angles are different at either end will running the prop out of phase to a greater or lesser degree improve the situation? I only ask as I had dreadfull rattle/vibration on a neutral throttle after a slight suspension lift. I did correct the angles and it's a lot better, also the front on my 4x4 has different angles from the factory and they run the prop out of phase, is this a poor compromise? Thanks for the great video.
No if the u joint phasing is not 100% correct it will make it worse. They are two different problems. One problem dose not fix the other only compounds the issue. This was a short clip of the entire video. I’ll try to find the entire video and send a link. Good luck
There may be but that would be above my skill level. There are tons of good info out there about the topic. Do you have to stay with a Cardan style joint or could you switch to a CV style? Here is a good link. www.machineservice.com/wp-content/uploads/2012/04/Driveline-Clinic.pdf And media.spicerparts.com/cfs/files/media/sHto4RMKzg7cmgEQQ/JOI-TEC-082%20Interaxle%20Driveline%20Phasing.pdf?token=eyJhdXRoVG9rZW4iOiIifQ%3D%3D&store=original
Not sure if it helps but Land Rover on the Defender have flanges that are not parralel on the front axle and transfer box, they run the front prop out of phase from the factory I presume to overcome the flange misalignment, the rear axle/transfer flanges are parralel and the rear props are in phase from factory.

Yeah that’s why i uploaded this. I forget where i got this. Think there is a longer version out there

Very good vid of the basics

I just signed up for this myself. May have some good information. I’ll keep looking for the full video.

X Mo thanks bud!

No prob!
Is it possible to achieve constant RPMs with an specific phasing angle between driveshaft yokes if your shaft are not parallel?
Thanks and regards.

Yes you can run the unis out of phase when flanges at each end are out of phase.
