REMOVAL & INSTALLATION



See Figures 1, 2 and 3

  1. Matchmark the base of the wiper arm to the linkage. This will assure that the arm is installed in the proper position. If the arm is being replaced, transfer the matchmark from the old component to the new one before installation. This can be done by placing the new arm on top of the old one and copying the mark.
  2.  
  3. Most wiper arms are retained by a spring clip. Some are equipped with a release tab at the center which should be depressed to release the arm. If no tab is provided, use a small prybar or a wiper arm removal tool (such as J-8966) to depress the spring and release the arm. Remove the arm from the vehicle.
  4.  
  5. Some models are equipped with a wiper arm that utilizes a small release hole at the base of the wiper arm. If equipped, insert a 1 / 8 in. (3.25mm) drift pin into the tool access hole to release the locking device and allow the arm to be easily pulled from the transmission. If necessary, use a gentle rocking motion to remove the arm.
  6.  

To install:
  1. Except for late model vehicles equipped with the tool access hole, align the matchmarks and gently press the blade over the linkage and snap into position.
  2.  
  3. For models equipped with the access hole on the arm, straighten the arm assembly and insert the pin. Align the arm with the linkage mark made earlier, then press down on the arm's head casting until it seats and locks onto the wiper pin. Remove the drift pin.
  4.  
  5. Operate the wipers and verify proper alignment.
