Because windshield wipers have become larger, wiper arms are pressure-fitted to the posts so they will not slip. They are then secured with a nut to hold the arm in place so they will not lift. Until now, it was almost impossible to remove these wiper arms without breaking or damaging them or scratching the cowl. With the Equalizer Wiper Puller for Bolted-On Wipers, simply remove the wiper nut, slide the tool over the arm until the jaws touch the wiper post, then turn the T-handle clockwise until the wiper arm pops from the wiper post. Comes with a revolving concave head to keep it from slipping off of the wiper bolt and has a steel joining cross-member for extra strength.
