Well, after a lot of research and a worsening of the problem I landed on the rear driveshaft as a likely culprit. Removed it and found that the rear most ujoint was sticking in one direction. Drove the rig with it off and CDL on, and sure enough that was the issue. So I regreased and worked out the ujoint, then reinstalled the driveshaft, and sure enough the vibration is gone.
