Vibration and Noise Issue

Well, i think I got most of it figured out. There is still some noise, but I think it's because the pinion snubber appears to be loose. They may have just worked out some from all the shaking, but that might be the scraping noise, we'll see. The shake is down from car rattling bomb to very slight buzz. It turns out I may have had the wrong U joint straps installed. i was thinking I may have just had too small of a U joint on and needed a conversion joint since the driveshaft would turn just slightly in the pinion yoke, but the bearing cups seemed to fit snug enough, they just weren't being held down tight enough. Took the straps off the old axle and bolted it back up and it seems to run much smoother now.
