    Welcome to the club!!!

    Did you mark the driveshaft before you removed it? If not then it is out of position, the driveshaft is balanced and installed a certain way. As far as the slapping noise I don't know, hopefully someone else can chime in.

    Thanks for the info, this shaft has yolks welded on both ends, so I done believe it can get out of time? One end bolts to the rear pinion, and one has a spline going it the transfer case.
