The first step to servicing the liftgate hinge is releasing the latch, opening the liftgate and holding it up with a suitable rod. Stick some tape against the roof around the hinge and then detach the trim panel from inside the trunk. If you can't reach the bolts from the top, you may need to uninstall the headlining to gain access. Place marks on the liftgate hinge, showing where the liftgate studs are located, using a suitable marker. After that, take out the nuts that secure the hinge to the liftgate, plus the cover. Unscrew the liftgate hinge bolts and retrieve any shims from in between the hinge and sport bar before taking out the liftgate. Start with the liftgate hinge on the vehicle, then put any retrieved shims between the hinge and the sport bar and install the bolts to connect the hinge to the roof panel. Loosen the nuts on the hinge, place the liftgate so the studs fit over the marks and tighten the nuts to hold everything in place. Add the hinge cover, headlining and trunk trim panel and then operate the liftgate a few times to make sure it is working well and properly aligned.
