Anytime the enigine is turning, that shaft is turning.
Pull drive, inspect u joints.
I'll bet they are toast.
A great way to kill them is to run the engine in trailer up.

While the drive is off, turn the gimble bearing and check for any roughness, inspect the bellows for cracks, and inspect the shift cable bellows for cracks.

Look into bellows through gimble and check coupler for pointy teeth.

Check the engine for alignment also....you need a tool to do so.

Hint: To pull the drive, shift into FORWARD
