EXTERIOR | DOORS | ADJUSTMENT
(See Figures 1, 2 and 3)

1. Check the gaps around the door. The gaps should be even.
   
   
2. Adjust the spacing by loosening the hinge mounting bolts and moving the door in the direction necessary to even out the gap. Move the door in small increments.



3. Adjust the panel height at the front edge of the door by inserting hinge shims between the hinge mount and the body. The hinges are available in 0.020 inch (0.5mm) and 0.039 inch (1.0mm) thicknesses.
   
   It is acceptable to have the front door edge set lower than the front fender by up to 0.039 inches (1.0mm). This will help prevent wind noise and stone chips.



4. Adjust the rear edge of the door by moving the door striker in or out.
