my spline gears were stripped out and would spin inside of the wiper arms leaving me wiper less. so i went to the local auto parts store and got jb stick weld and put it around the shaft and put the wiper arm back on it, next morning the wipers worked fine. just thought u guys should know, only down fall is to get underneath where the motor is ur gonna need to get the passenger wiper free again but i dont think its that needed.

 

If there is a little bit of thread/ridges left, steel wool works too. Have fun if you ever need to remove the wipers or change out the motor.

 

ha i plan on it
