The Nissan Path

Just changed out the u-joints from both drive shafts on my 09 SE 4WD. Reinstalled everything exactly where I marked it. Went about a week and now get a steady vibration starting at about 65MPH on the highway or country roads. Took the front driveshaft back off and the vibration diminished significantly (to almost nothing). Could the actual front shaft be bad?

it could, if it's bent or out of balance
is it possible that the new joints are a problem, or perhaps not properly installed?
