    Hey,Im doing new u-joints on my rear driveshaft 77 k10 and it has that slip joint on the end that goes to the transfer case.Ive noticed that it will line up on any spline i try it on.My ? is are both u-joints supposed to be lined up with each other or what?Is this phasing the only thing in the stupid haynes manual is if it is a 2-piece shaft with the center support.I dont have that so i just want to be sure before i install it

    I think driveshafts are balanced with the slip joint assembled. That means you want to be able to put the slip joint back together in the same psition that it came out. Since it sounds like you've already got it apart, I think the u-loint yokes need to be oriented 90* frome each other at either end. Does that make sense? If you go driving and have any vibration, you could try flipping the sleeve shaft 180*. Just my $.02
