Up/Down or In/Out Adjustment Procedure

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

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

In order to adjust the door striker in an up/down or in/out direction, perform the following procedure:

The door must be properly aligned.
Loosen the striker screws.
The floating cage plate can be moved slightly using the ends of the striker screws. Move the floating cage plate to the desired position.

NOTE: In order to oblong the striker mounting hole to assist in further striker adjustment, use a die grinder with a flat-headed grinding bit. This type of bit will help to prevent damage to the tapered floating cage plate. The striker and the tapped floating cage plate are important attaching parts that could affect operation of the door closing and latching systems.

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 with a flat head in order to enlarge the body opening in the direction required.

NOTE: Refer to Fastener Notice in Cautions and Notices.

Tighten the striker screws to the correct position.
Tighten: Tighten the door lock striker screws to 24 N.m (18 lb ft).
