I adjusted mine years ago. The passenger side. Used a small puller to remove the arm. Spined on tight. Before I removed the arm, and blade. I marked the old position, with blue masking tape. For reference.
My wiper arm on the passenger side, when on the high speed. Use to hit the inside of the A pillar. During a heavy rain storm.
