REMOVAL & INSTALLATION



All factory installed door hardware attaching screws contain an epoxy thread-locking compound to ensure that the torque setting will be maintained. Service replacement screws may not contain a thread-locking compound. Such screws must be treated with No. 1052279 Loctitereg; 75 or equivalent. The adhesive is placed on the fastener prior to installation.

  1. Disconnect the negative battery cable. Mark the position of the door hinges-to-body to make the installation easier.
  2.  
  3. If equipped with power operated components, remove the trim panel and detach the inner panel water deflector enough to disconnect the wiring harness from the components. Separate and remove the rubber conduit and the wiring harness from the door.
  4.  
  5. Using an assistant (to support the door), remove the upper and lower hinge-to-body bolts. Remove the door from the vehicle.
  6.  
  7. To install, reverse the removal procedures. Tighten the hinge-to-body bolt to 15-21 ft. lbs.

If a rearward adjustment is made, it may be necessary to replace the jamb switch.
