I need to install a SYE to stop vibration. I was looking at the Tom Woods SYS kits. The direction says to point the rearend yoke pointing up towards the rear of the Tcase. Is this just to get the measurement for the driveshaft or does the rearend yoke point up even after the install? If so, how do you point the rearend yoke towards the Tcase? Do I need adjustable control arms or some other high dollar piece? Any info would be a big help at this point. Running low on funds and still don't have my rig driveable.
