"Install the arm by inserting into the screw with the tip of the arm aiming at the ground. This allows a very good fit of the entire arm to the base of the motor and eventually flush with the surface of the glass.

While holding the arm down with some force, gently bring the tip of the arm to the edge of the rear glass, making the arm and the wiper blade as horizontal as you can to the edge of the glass.

Now tighten the 13mm nut holding the arm to the base and put back the cover.

Doing both the spring lube and the arm re-position brought my wiper back to 100% functionality!"

Will try this out when I get my engine repaired!
