New vibration after driveshafts replacement

Changed out L and R drive shafts on my 92 Accord EX-R 5 speed due to blown
boots. I now have a weird vibration when accelerating hard, most noticeable
in 1st and 2nd gear.

Any ideas where to look? Everything is tight, I've swapped shafts before, no
surprises...except the vibration, of course. I'd like to minimize my parts
swapping for diagnosis.

A bad shaft?

Haven't taken the old shafts back yet for cores.

Thanks

I know that there are a vocal many who insist that reman. shafts are
shite. No ideas on your problem.

 

It could be as simple as a worn out inner joint, that wasn't caught by the
place the rebuilt the axle.

Truly remanufactured shafts are fine if the were built by someone who knew
what they were doing, and who is fairly trustworthy. Now I have seen shafts
from parts houses that had the inner joint assembled improperly causing it
to bind up or cause pretty bad vibrations. I've also seen a few bad 90-93
accord 5 speeds transmission that would cause noises or vibrations.
