For a while I thought the squeaking was just the blades on the glass, but then I ran it with the blades lifted and it was still squeaky and slow. Turned out to be the two bearings built into the right-side wiper arm. The streamlined plastic cover is just clipped on, but the clips are really stiff and it's hard to remove. Also unnecessary, because squirting oil in from the bottoms of the bearings worked better than squirting from the top anyway, and the bottoms are already exposed. -Chap
