CAUTION: Do not apply pressure to, or pry on, the plastic drive link bushings. When removing a drive link from, or installing a drive link
onto the ball stud on the wiper motor crank arm, apply pressure to, or pry on, only the metal portions of the drive link around the bushing. If
the bushing is damaged, the entire front wiper module MUST be replaced.
CAUTION: Do not remove the crank arm nut from the wiper motor output shaft. The crank arm is indexed to the output shaft with the motor
in the park position during the manufacturing process, but there are no provisions made for correctly indexing this connection in the field. If
the crank arm to output shaft indexing is incorrect, the entire front wiper motor and crank arm unit MUST be replaced.
1. Use large channel-lock pliers to grasp and rotate the front wiper motor crank arm (2) so that it is positioned parallel to the axis of the wiper motor
(3) armature and the ball stud (1) on the crank arm is at approximately its furthest point from the motor, as illustrated.
2. Position the wiper motor and crank arm as a unit onto the motor mounting bracket (5) of the front wiper module.
3. Install and tighten the three screws (4) that secure the motor to the bracket. Tighten the screws to 5.5 Nm (48 in. lbs.).
4. Position the sleeve bushing of the left wiper drive link onto the ball stud on the end of the motor crank arm. Place a short 19 millimeter or 3/4 inch
socket over the bushing as an installation tool. Then use large channel-lock pliers to apply enough pressure to the underside of the crank arm and
the top of the socket to snap the bushing onto the ball stud. Do not apply pressure directly to the plastic bushing.
5. Position the socket bushing of the right wiper drive link over the ball stud on the crank arm. Place a short 19 millimeter or 3/4 inch socket over the
bushing as an installation tool. Then use large channel-lock pliers to apply enough pressure to the underside of the crank arm and the top of the
socket to snap the bushing onto the ball stud. Do not apply pressure directly to the plastic bushing.
6. Reinstall the front wiper module into the cowl plenum. See: Wiper Module - Installation.
