If I had four u-joints I can see getting out of phase, with three u-joints there is only one way they can go together, or am I missing something? Two shafts with one joint in between and one joint on each end. I think the yokes are stationary on the shafts and splined yoke on the pinion and IDIDIT. The small shaft that goes through the eye has to be removable, I will look closer at that.
Thanks
