Rear Lifter Arms
WARNING: This page is about a different car, the 2015 Lincoln MKZ. However, it is still accessible from the selected car via links, so may be relevant.
The rear lifter arms are idler links that connect the glass to the frame and slides along the rail as the glass moves open or closed. The rear lifter arms come pre-assembled with all sliders, shoes and bushings necessary for moving the glass along the frame rail.
