After the front ds is out, roll your vehicle unil the ears that are affixed to the motor are vertical--one ear up and one ear down. Lift the front end off the ground and get the yoke nearest the diff vertical like the rear. Once you are sure that you have perfectly matched them, get your shaft, put it in the back yoke and go to the front and put the ds in the diff yoke. Once you are sure it's all good, stuff the diff into the mounts and check again. Still good? Tighten the diff into place and ride.
Here's a link that another member provided that shows the phasing (toward the end) the rest doesn't matter for Rhinos--unless you want to do some fabbing to move the front diff towards the passenger side. Beware that a Rhino doesn't have a ds like a normal vehicle. The joints are affixed to the diff and motor. The illustration just shows how the yokes should be with regard to one another.
