Installation Procedure


    Object Number: 215280  Size: SH
  1. Position the wiper arm on the transmission drive shaft so that the wiper blade aligns with the mark made during removal.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
