Hi all My wipers failed yesterday in heavy rain. I went at it today, they had been operating faultlessly til now. I could hear the motor operating so reckoned linkage. This is what I found lying loose in the wiper bay. As there seems to be nylon liners that go over the ball section I assume that my issue is wear on the nylon. So, my question is, I can buy new arms online, sold as a pair, do you think popping on a new short arm is the way to go. I assume that this is possible without removing the linkage assembly completely. Thanks in advance. Mike
