I just removed both of my wiper arms with a $7.00 puller. Right side came of in a minute but the left side had the hood close. Unscrewed handle and put a smaller screw (1.25") with small washer and nut, with threads up through the hole and screw head down towards the stud. Had wife hold U shape puller over stud as I held screw with needle-nose and small wrench worked nut UP and screw head pushed down on wiper arm stud.
