Rear Side Door Lock Striker Adjustment With Mini-Wedge Aligner

Tools Required

J 39346-A Mini-Wedge Door Striker Aligner

Important: The door must be properly aligned before adjusting the striker.

Adjust the striker.

  1. Loosen the screws just enough to allow movement of the striker.

  3. Close the door while holding the outside handle in the open position.

    4. Do not slam the door.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. 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.

    Tighten the door lock striker screws to 25 N·m (18 lb ft).
