Driving through the rain xmas day (3-4 hours), I could hear a loud squeak. When I stopped to get gas and started back on the road, squeak start up again after 15-20 minutes, is there a bushing that could wear out in the driver side wiper?

 

Are you sure it's not the rubber on the wiper rubbing on the windshield ?

^ I know that when the word "rubber" is shipped 3000 miles across the Atlantic it takes on another meaning.....in that case you really would have a problem if it squeaked !
^
^ mind you in that case the squeak may not be coming from the rubber !

 

ROFLMAO, yes I am quite sure and thanks for making my day!!
It would REALLY have been a problem, because I was driving 75 mph in the rain, I am good but not that good. Though I have not dained to take on that feat.
