Note: The door lock striker is an important attaching part that can affect the performance of vital components and systems. It can cause major repair expenses. If replacement becomes necessary, the door lock striker must be replaced by one with the same part number or with an equivalent. Do not use a replacement part of lesser quality or of a substitute design. The specified torque values must be used during reassembly to ensure the proper retention of the part.

The door lock striker consists of a striker with 2 screws that are threaded into a tapped, floating cage plate located in the appropriate body pillar. This floating cage plate allows the striker to be easily adjusted in and out or up and down.

The door is secured in the closed position when the door lock fork snaps over and engages the striker.

Up/Down or In/Out Adjustment

An adjustment of the striker in the up and down or in and out directions may be necessary for a number of reasons:

    • Vehicle frame damage as the result of a collision
    • Installation of new door weather stripping
    • Customer complaints of excessive windnoise
    • Difficulty in opening or closing the door

To adjust the door striker in an up and down or in and out direction, perform the following procedure:


    Object Number: 1256818  Size: SH
  1. Ensure the door is properly aligned.
  2. Loosen the striker screws.
  3. Note: It is important to use a flat-tipped drill bit to prevent damage to the tapped floating cage plate. The striker screws and the tapped floating cage plate are important attaching parts that could affect the performance of vital components and systems.

  4. The floating cage plate can be moved slightly using the ends of the striker screws. Move the floating cage plate to the desired position.
  5. If proper adjustment requires that the floating cage plate be moved more than is possible, use an electric hand drill and a 3/8-inch rotary file bit with a flat head to enlarge the body opening in the direction required.
  6. Caution: Refer to Fastener Caution in the Preface section.

  7. Tighten the door lock striker screws to the correct position and tighten to 24 N·m (18 lb ft).
