Lower Door Adjustment
If the door does not latch properly after installation, if
there is interference between the panels, or if a
non-uniform gap around the door is observed when the
door is closed (example: door position appears to be low
and too far rearward), the position of the door on its hinges
may need to be adjusted. To do this, proceed as follows:

1. Loosen (do not remove) the four bolts on the door
hinges using the provided #T50 Torx head driver.

Hinge Bolt Locations

NOTE:Do not adjust the body mounted hinges, or any part of the
door latch, as modifications to these parts will affect
installation of the full door.
2. With the bolts loose, the door can be moved forward by pushing the door handle toward the front of the
vehicle, and/or upward by grabbing the door handle
and lifting towards the roof.
3. Once the gaps between the door and vehicle body are uniform around the entire door, tighten the door
hinge bolts to 20.3 ft· lb / 27.5 N·m (Max Torque:
27.3 ft· lb / 37 N·m).
Upper Door Adjustment
After installation of the half-doors, if water leaks or wind
noise is observed, the seal of the upper half-door to the
door opening may need to be adjusted.
To determine if the upper half-door needs to be adjusted,
proceed as follows:

1. Determine which door is affected.

2. Open the affected door and hold a dollar-size piece of paper along the top of the door opening against the
vehicle near where the leak/noise was observed.
Make sure half of the paper is above the area where
the door seal contacts the door opening, while the
other half is below. 3. Close the door on the paper, then pull the paper
upward. If the paper moves with little to no effort, the
upper half-door will need to be adjusted in that area
to increase seal compression.

Performing A Paper Test

There is another optional test that can be performed using
a flashlight and the help of another person.
One person should be inside the vehicle, and move the
flashlight around the periphery of the door seal, shining
outward. The other person should stand outside of the
vehicle and check for light passing by the seal. If light is
seen through the seal area, the door will need to be
adjusted.
CAUTION!
Upon first installation of the half-doors, slowly close
each door to check for body contact. Improper setting of
the door hinges can cause extreme non-uniform
conditions, and result in damage to the body around
the door.
