Before installing the trunk or liftgate hinge, you should remove or move the hinges with a suitable body sealant. If it helps, paint the replacement hinge before fixing it. Remove the headliner cover, set the nuts and bolt onto them and tighten the fasteners until they reach 15 Nm (11 ft. lbs.). Add the liftgate bolts and then tighten them up to 15 Nm or 11 ft. lbs. Fit the harness from the top of the tractor to the liftgate and join the washer hose to the opening in the liftgate, adjusting the liftgate if needed. In the end, fit the headliner at the top, back part over the frame and use both push pin fasteners to hold it.
