Check the obvious first, I had this happen. Maybe loose tranny to bellhousing bolts. Missing or bad pilot bearing.

There might be some play in the 3rd member. Put some blocks under the tires, and set the E-brake, then put the truck into neutral. Then twist the driveline to the left, then to the right. Does the driveline move, or is it solid?
