REMOVAL AND INSTALLATION
This procedure requires the use of a wiper arm puller tool or equivalent and a pin or pop rivet for articulated wiper arms.
- Disconnect the washer hoses.
See Figure 1
- Remove the nut cover from the wiper arm nut by twisting slightly with a 17mm socket. Try to gently pull the cover off. The cover may crack or break and need to be replaced.
See Figures 2, 3 and 4
- Loosen and remove the retaining nut from the wiper arm.
- Lift the wiper arm and insert a suitable pin or pop rivet completely through the two holes located next to the pivot of the arm, where applicable. A heavy duty battery terminal puller can be substituted to pull the wiper arm from the stud, in most cases.
See Figures 5 and 6
- Run and park the wiper motor.
- Install the wiper arm on the drive shaft.
- Install the nut on the drive shaft finger tight, then remove the pin, that was inserted near the pivot arm.
It may be necessary to allow for some movement of the arm when the nut is being tightened. If the arm moves away from the desired alignment mark, loosen the nut and reposition the arm by moving the blade tip. Retighten the tip.
- If installing the driver's side wiper arm and blade, measure from the tip of blade to the bottom edge of the glass. This must be approximately 5.8 in. (147mm).
See Figure 7
- If installing the passenger's side wiper arm and blade, measure from the tip of blade to the bottom edge of the glass. This must be approximately 1.3 in. (33mm).
- Tighten the wiper arm nut to 29.5 ft. lbs. (40 Nm).
- Install the nut cover and connect the washer hose.
- Lift the wiper arm from the window and pull the retaining latch.
- Remove the wiper arm from the pivot shaft.
- Run the wiper motor to the park position.
- Install the head of the wiper arm on the serrated wiper pivot shaft in position where the wiper blade will rest in the proper parked position.
- Lift the arm extension and push in the retaining latch when the head is fully seated on the pivot shaft.
