No they call that put of phase and it will cause a lot of bad vibrations and other problems. the yokes on any driveshaft should be in line with each other or it will rattle apart.

I've had lots of discussions about where the yokes should be. I started off with them at 90 because that's where my buddies were on his Jeep. Then on some other boards I was persuaded to change them because others had more experinence, they said the same thing that at 90 degrees it will tear everything apart. The best part is that all I have to do is pull it apart and move it!
As long as the crosses of the u-joint are in the same plane, it doesn't matter where the yoke sits (0-90-180-270). What would tear it apart would be one at a 45* angle to the other (or even more than maybe 5* different). The other factor for vibration would be if the output on the t-case and the pinion are at the same angle.
As the u-joint moves thru it's arc, the drive shaft actually changes speed. As long as the u-joints are phased correctly, and moving in the same plane, then both ends change speed evenly. If one end has to move farther, or the u-joints are out of phase, then the 2 ends are trying to move different speeds at different times, and they vibrate.

Um... folks these ARE 90* out of phaseOriginally Posted by northplainsdrifter
Not in-phase like a regular drive shaft.

Square driveshafts are for Toyotas.
I took it out and hammered on it all weekend with great results! I am really happy with my new driveline =D> espeicially since I only have about 60 bones in it! I ran hi-range most of the time with no problems, I could hear a little noise when I was going back and forth from camp to the dunes which was the slop between the two tubes. I think I will keep it dry, no grease, for the time being. I would think grease would eliminate the tink tink tink I hear but with no dust caps I'm afraid everything would stick inside, especially the sand.
Couple of shots from Sand Lake on the Oregon Coast.
P.S. I left all the Toyotas with round drivelines at the bottom of the dunes.
