I appreciate everyone's comments.
767Flyer and myself BOTH had incorrectly installed front lower control arm bushings. The bushings are part of our problem, but not the ultimate fix. Both of us are still working on it.
I have not tried the center hump test, I just put my hand on the side of the center console. I do get SOME vibration there, but its not bad compared to when I've got rear tires out of round... Do you feel ANY vibration there? I have the parts on my shelf, but have not yet installed them as I did not think driveshaft would cause steering wheel vibration....
