These pictures are not going to tell you if a wiper arm is sufficiently bent to cause the problem. A subtle bend causing less than even pressure across the length of the blade will cause the blade to streak or chatter. Given the steps you've taken so far, I would suggest replacing one wiper arm to see if the problem is corrected. If not, return the arm, at which point the question would be whether the new windshield is slightly misaligned.So I have come to the conclusion that both of my wiper arms are bent. I assume this happened when I got my windshield replaced. I confronted my Mazda dealership, but they are not taking ownership of the issue. I’ve attached an image of the driver side bent wiper arm below. If you guys could send me a picture of your wiper arm, so I could compare it to mine, I would appreciate it a lot!
