Bad Vibration
I have a vibration in my truck that I am seriously worried about. When I am driving at slow (20mph or less) speeds it doesn't do it. But once I get about 30mph or so it starts to vibrate. When I accelerate it vibrates and when I am inbetween accelerating and coasting it is at its absolute worst. The weird part about this is when I am completely coasting there is no vibration. Any ideas on what might be causing this. It just starting doing it a couple of days ago. Thanks.

Check your driveline for play as well. I have a problem with the xfer case tailshaft/yolk being worn which behaved exactly this way. Unloading the driveline allows it to center and quiet down. So you may have something allowing the driveshaft to push off center. I agree you should check your pinion nut first, but while you are there, check the tailshaft fit or anywhere the driveshaft can go off-center.

how hard and time consuming it is to replace the U-joint? Also, if that is the case should I replace the yoke as well? Thanks again. Hopfully I can get this taken care of before I have to leave town next weekend.
