DOOR LOCK STRIKER ADJUSTMENT
(Front Door Shown, Rear Door Similar)
The door lock striker consists of a striker with two screws
that are threaded into a tapped, floating cage plate located
in the appropriate body pillar. This floating cage plate al-
lows 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.
Notice : 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 re-
placement 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.
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:
S Vehicle frame damage as the result of a collision.
S Installation of new door weatherstripping.
S Customer complaints of excessive windnoise.
S 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:
1. The door must be properly aligned.
2. Loosen the striker screws.
3. The floating cage plate can be moved slightly using
the ends of the striker screws. Move the floating
cage plate to the desired position.
4. If proper adjustment requires that the floating cage
plate be moved more than is possible, use an elec-
tric hand drill and a 3/8–inch rotary file bit with a flat
head to enlarge the body opening in the direction
required.
Notice : It is important to use a flat–tipped drill bit to pre-
vent 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.
5. Tighten the door lock striker screws to the correct
position.
Tighten
Tighten the door lock striker screws to 24 NSm (18 lb–
ft).
