speedometer needle jumps around PONTON

My speedometer needle is erratic as hell. At low speed it seems to work but at higher speeds it starts jumping around.


I took the cable out and inspected. Looks fine not worn or spun. (replaced with a old spare same results)


Took the speedo out of dash , ran it with a drill motor, works fine .


I have the tranny out right now. Should I take apart the bronze worm gear? Does anyone have any experience with this? Hard to believe the worm could wear out.


THANKS!!!!!
