Windshield wiper arms fit on a stubby knurled post that sticks out though the cowl. My passenger side wiper knurl is worn it is embarrassing to lose an arm in a rain storm – and you get wet trying to retrieve it. I added a glob of RTV to the wiper arm socket.

This seems to work, but is there a repair kit for the little knurled post other that replacing the whole pivot and pulley assembly?
