Ok thanks, I will probably go to this solution if I cannot resolve the issue with my truck. My issue seems to definitely be the driveshaft itself, as I tried the old school hot rod trick and put hose clamps on the front slip yoke for balance against a high spot I measured with my dial indicator, and the vibration did in fact change. Not to say the driveline angle couldn't be a source of the issue as well. If I could avoid manual hubs I would prefer to, mainly to have the ability to just throw the shift knob down and have 4x4 action. My trucks's theme is a lot like the Ramcharger from Lone Wolf McQuade, basically a truck that is decently quick for what it is, handles well and has good on-road 4 wheel drive capability. Mostly for light terrain and snow, probably little to no actual trail offroading.
