That may not be the only reason it was removed.

Yes, check the condition of your U-joints.

It is doubtful that a mere mortal would be able to detect the imbalance.

Unless the damper was also removed, there are only 4 "combinations" to try.
But, that is a futile exercise because the driveshaft was not balanced in
situ.  If the driveshaft was separated at the rubber damper, it should be put
together with the U-joints in phase.  Check the condition of the front wheel
bearings, CV-joints and center driveshaft U-joints.
