Hey guys, I ran a search and didn't find anything. In the rain today my wipers started making a really annoying high pitched squeak. It's probably 17 - 18 kHz, so some of you older guys probably wouldn't hear it at all When I got home I lifted the blades off the windshield and the squeak was still there. It is coming from the housing where the wiper arms pivot but couldn't tell if it was louder on the passenger or driver side. I'm bringing my car in to the shop anyway on Monday for some other issues. Do you guys have any suggestions on what it could be? Sounds like something needs a little WD-40.

Thanks
Spencer
