Yes, I think you should go back and check again if the shafts are "in phase". The bearing caps must be at the same angle and if the slip yoke has been disassembled and not put back together correctly you will have 2 vibrations per every revolution. The half shafts rotates about 1400rpm @ 100 mph so its fairly low rpm compared to i.e. a propshaft which usually follows engine rpm´s in the final gear. Also if the slip yoke is severely worn it can contribute to being out of phase I suppose. But check the phasing again! there are arrows marked on the 2 parts that must align.
