  Q: How to replace the wiper arm on Chevrolet Express 3500?

  A:

  Begin by placing the wipers in park position before dismantling the washer hose from the air inlet grille panel. Take off the protective casing from the Wiper Arm nut and then unscrew the nut. If the Wiper Arm stays fixed on the Drive Shaft try both a Wiper Arm puller (J 39822) or a battery terminal puller to remove it. After breaking free use the tool to pull off the Wiper Arm ahead of removing the Wiper Blade. Install the Wiper Blade onto the Wiper Arm and secure it to the Drive Shaft by positioning the Wiper Arm until its center falls between the black locator dots on the lower center windshield. The wiper arms function correctly only when installed based on their stamped markings. Position the Wiper Arm close to the air inlet grille before tightening its nut to 26 n.m (19 lb ft). Reinstall the air inlet grille cover after you tighten the nut. Then reconnect the washer hose elbow to the air inlet grille panel. Test the wiper movement to confirm it works correctly.

  Q: How to service and repair the wiper arm on Chevrolet Express 3500?

  A:

  You need to first park the wipers and pull off the washer hose elbow from the air inlet grille panel when repairing the Wiper Arm. Peel back the cover from the Wiper Arm nut and then take out the nut. Should rocking the Wiper Arm not work to remove it, use a battery terminal puller to help you get it off the Drive Shaft. When it is loose, carefully rock the Wiper Arm side to side to remove it from the Drive Shaft, then take off the Wiper Blade from the arm. When installing, put the Wiper Blade on the Wiper Arm and be sure not to confuse the left and right arms, as they're clearly stamped. Make sure the measuring device is at a 90-degree angle to the Wiper Blade as you attach the Wiper Arm to the Drive Shaft, making sure the lh tip is 70 mm (2.75 in) and the rh tip is 65 mm (2.56 in) away from the air inlet grille panel. Put the nut onto the Wiper Arm and tighten it to the correct torque of 26 n.m (19 lb ft), then cover it. After that, connect the washer hose elbow to the air inlet grille panel, and activate the wipers to make sure they are working.
