    Anyone else experience the wobble as shown in this video? The bottom of the driver wiper wobbles under certain wetness conditions.

    Yes. Had the exact same thing. Went away completely with new Bosch icon wipers.

    Hmm... we had it in for the annual about a month ago and they put on the new Bosch blades and inspected the brackets, etc. There must be something else to it.

    Yep, mine wobble too, maybe they are afraid of the ghosting.

    I bought the Bosch icon blades as they are supposed to be better than the stock Bosch blades. But, I don't have that in writing... For all I know, the difference may just be new vs old.

    Replace the 28 in blade with a 26 in blade that should solve the problem. Amazon has them. No meaningful change in swept area.

    Yes, mine wobble under most conditions and has since new. The SC said "engineering is aware of the issue" and didn't do anything. I've since asked them for an update and they said there was no update or anything they could do about it.

    Maybe you'll have better luck with your SC.

    Happens to everyone as far as I know. Bosch Icon blades really help. In my case I had good results thoroughly cleaning and polishing the windshield and then using RainX. Others have had issues using anything like RainX on the windshield … I think the key is really cleaning and polishing before you apply anything.

    This happened to me right after applying RainX to the windshield. It went away on its own after a day or so.

    It's not RainX. It's a design and part problem:

    The reason is improper tolerances on the wiper bracket. If they are slightly loose (which they are) they will wobble until the keep making the bracket even larger, and wobbling even more, and repeat. My solution was simply to use a small C clamp to press the metal side of the bracket until there was a solid connection to the wiper side of the bracket. No more wobble. For now.

    Would love to see a picture. You leave it there all of the time? Is the problem on both sides?

    Thank you!

    C-clamp is only to bend the metal bracket down to a tight fit in a controlled way. It does not stay on the wiper.

    edit - and the problem is more with the driver side since the wiper arm is so long (more torque). I left the passenger side alone, because even when loose it doesn't really chatter.
