I've always thought of tire unbalance as more of a shake (or low-frequency vibration) and bad u-joints as more like a high-frequency vibration...... possibly what you are describing.
Good luck, if you throw new u-joints in, I hope that fixes it. Keep us posted!
Your truck sounds like a real workhorse. I retired from telecom construction and some of our rigs got a pretty good workout at times.... same with the power company trucks!
Incidentally, my truck also has a Q-jet (OEM) on an Edelbrock 2101 Performer that I got when my stock cast iron intake cracked. Pretty good setup for all-around use IMO.
