Start by setting wipers into park position while disconnecting the washer hose elbow from the air inlet grille panel. Get rid of the Wiper Arm cover nut and remove the corresponding Wiper Arm nut. To break the Wiper Arm's connection from the
Drive Shaft, first try rocking it back and forth and then use the Wiper Arm puller (J 39822) or a battery terminal puller. Avoid using common screwdrivers on wiper arms. After loosening remove the Wiper Arm from the Drive Shaft before you detach the
Wiper Blade from the Wiper Arm. During installation replace the Wiper Blade to the Wiper Arm except avoid swapping the lh or rh wiper arms because they bear identifying stamps. Attach the Wiper Arm to the Drive Shaft by ensuring a 70 mm (2.75 in) spacer between the lh Wiper Blade tip and the air inlet grille panel and a 65 mm (2.56 in) distance for the rh tip. Slip the Wiper Arm nut onto its position then tighten it by 26 n.m (19 lb ft) force. Reinstall the washer hose elbow onto the air inlet grille panel before checking wiper operation along with securing the nut and replacing the cover.
