My 350SDL just threw the ball out of the plastic socket in the wiper transmission ... did you repair this one yours?
Is the bushing (plastic socket) available for replacement? Everything else looks OK on mine ... the one ball has popped out of what looks like a mildly cracked plastic socket cup ...
