    2. 1.1. Position the bolt-on service replacement hinges within the scribe marks made on the body hinge pillar at the time of the removal.
    1.2. Center punch each bolt hole location on the body hinge pillar and/or on the door.

  2. Prepare the surface for the replacement hinges using a file or a similar tool.
  3. Coat the mating surfaces of the hinges with a medium-bodied sealer.

    4. 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.
