Rear Window Liftgate Glass Hinge - Function and benefits - Enables the rear glass to open for ventilation or extra space when moving items. The hinge is mounted at the top of the glass and attaches to the body just below the roof, with a hinge bolt that allows smooth opening and closing, like a house door hinge. - Replaces a failing hinge to restore reliable operation and prevent the glass from falling or becoming hard to move. - Construction and maintenance - Hinge is typically metal and positioned on the outside of the glass, which exposes it to the elements. - Over time corrosion can occur, leaving mineral deposits beneath the hinge. If the hinge bolt corrodes, the hinge may become stiff or loose, making the rear window hard to open or to hold open. Replacing the hinge avoids these issues. - Compatibility and OE part numbers - Applications: 2008-2012 Ford Escape, 2008-2011 Mercury Mariner, 2008-2011 Mazda Tribute. - OE part numbers: - Left: 8L8Z-78420A68-D, 8L8Z78420A68D - Right: 8L8Z-78420A68-C, 8L8Z78420A68C - 924-123 - Use scenarios - Hot days: open the rear window to vent the cabin and reduce heat buildup. - Moving bulky items: create extra clearance to maneuver large furniture or appliances. - Routine maintenance: replace a stiff or loose hinge to maintain secure, smooth operation of the rear glass.
