OK, so I took the truck down to AZ driveshaft and they determined that my rear driveshaft was too short and causing the vibration under no load. I do have about 5" of lift on my '86. For all of those with lifted trucks, did you lengthen your rear driveshaft? I will be picking up the truck tomorrow and we'll see if this indeed resolved the problem... Stay tuned
