  Q: How to replace the wiper arm on GMC Savana 3500?

  A:

  Begin replacement by positioning wipers to park mode then disconnecting the washer hose structure from the air intake barrier panel. Take off the protective piece from the Wiper Arm nut and then remove the nut from the Wiper Arm. When rocking the Wiper Arm fails to disconnect it from the Drive Shaft please use either the Wiper Arm puller (J 39822) or battery terminal puller to help with removal. Unscrew the Wiper Arm until it becomes free from the Drive Shaft and take it off from there. Separate the Wiper Blade from the Wiper Arm. Fitting the Wiper Blade on the new Wiper Arm requires caution not to mix left and right side wiper arms which have fixture markings showing their intended positions. Put the wiper's central point over the lower black windshield markers and place the Wiper Arm on its shaft area. Secure the Wiper Arm nut by keeping it near the air vent space during tightening to 26 n.m (19 lb ft). Ensure the wiper operation quality by running the system when you finish installing the nut and connecting the washer hose elbow.

  Q: How to service and repair the wiper arm on GMC Savana 3500?

  A:

  You should set the wipers to park position before removing the washer hose elbow from the air inlet grille panel. Lift the protective plate while unscrewing the wiper nut before taking out the Wiper Arm's nut. When rocking the Wiper Arm does not work to detach it from the Drive Shaft try the Wiper Arm puller (part J 39822) or a battery terminal puller instead. Move the Wiper Arm side to side to detach it from the Drive Shaft before taking off both components together. Install the Wiper Blade onto the Wiper Arm before fitting it onto the wiper Drive Shaft. Also normalize the wiper arms because each Wiper Arm carries a corresponding indicator stamp to prevent swaps between the left and right side. Place the measuring tool at right angles with the Wiper Blade and put the Wiper Arm onto the Drive Shaft. Keep a 70mm (2.75inch) gap for lh Wiper Blade tips and 65mm (2.56inch) gap for rh Wiper Blade tips starting from the air inlet grille panel. Frankly attach and fix the nut by turning it to 26 n.m torque before you put covers back and place the washer hose back into the air inlet grille panel. Test the wiper function and examine if the system works correctly.
