Today my wipers suddenly stopped, followed by much clunking. On investigation, the rod from the motor had fallen off the wiper arm lever. I greased it and put it back on, but a few miles later it came off again.
There seems to be a rubbery washer that sits over the ball, then the socket connects to the ball. It doesn't connect very well though, and Im not sure which bit is worn. What is the best thing to replace? It's all back together now, and its dark out - can I replace the ball and socket bits without replacing the rods or is it too much faff, and I'd better off looking for a full mechanism on ebay etc?

To make it easier to see, its the two orange arrowed bits that fall apart...

I thought of maybe drilling through the two bits and fitting a bolt/washers/nylocks to hold it all together but allow it to pivot?

My first car kept doing this (Nova, dont laugh!)

Either swap the arm, or do as you suggested :L
