You need to check the drive shaft and U-joints.  Any bending, imbalance, or
wear will cause this symptom.

from the rear of the van

However, reading the archives suggests that it also could be the
transmission? (After all, I was rocking that baby back and forth on the
beach!). Is it possible that the BFG All Terrain tires got damaged in some
way? I don't see any obvious gashes or rocks between the treads. NOTE: I
also didn't see any obvious tears in the CV joint rubber.
