    E30 1st and 2nd gear vibration

    Hey guys. i just installed a new flex disc and center support, now there is a vibration when its in low rpms in 1st and 2nd gear. What can cause the vibration? Can it be the driveshaft its unbalanced?

    Was the rubber mount of the CSB torn? If so the probable cause of the CSB failure and the vibration in the lowest gears is binding drive shaft u-joints. The only fix is replacement of the drive shaft.
    The car makes it possible, but the driver makes it happen.

      Did you mark the drive shaft before taking it apart?

        Mis-assembly of the drive shaft probably won't cause any problems in the lowest gears since the drive shaft speed is low then. It would be more likely to cause problems at high speed when the drive shaft is spinning fast.
