Fore/Aft Adjustment
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The liftgate and liftglass are adjusted together in this direction. The liftgate hinge can be adjusted fore/aft on its D-ring attachment surface through a mean shift in the pierced net hole on the D-ring.
