The driveshaft is still bolted in but the vibration is back and just as bad as it was for the 6 weeks. I guess it wasn't the driveshaft causing the problem but it was the result.I am scared. Reading some forums I found the problem could be maybe i installed the shaft 180 degrees wrong. Also maybe the guy who did the rebuilding messed it up but I doubt that. Advice - don't keep driving with that noise.
