Park the unit on level ground.
Put chocks on tire, font and back.
Place transmission in neutral, do not start engine!
Release the parking brake.
Get under unit and manually rotate the drive shaft at the U joints, when the U joint is vertical push up and down, if no movement rotate 90 degrees and repeat, if the U joint moves up and down on the fork, the U joint is worn and needs to be replaced.
Same noise would be heard if you shift from reverse to drive and back again with the engine running, a metallic clank, this will be the pinion and the crown, if it is louder a U joint might also be contributing to the noise.
