Driveshaft/propshaft u-joints should feel 'smooth' as the shaft is rotated by hand (with the u-joint tilted at a typical angle). If they feel 'jerky' they are binding. (The jerkiness is what induces vibrations)
Often, vehicles will experience the issue after they get a few miles on them (or different height tires or suspensions are fitted).
Since you removed your AWD driveshaft and the issue remained, there is no need to replace the u joints IMO. You MIGHT have a front CV joint causing the vibrations though.
