Dorman - HELP Windshield Wiper Arm P/N:42879
Help your rear wiper sweep the glass cleanly again with the Dorman wiper arm, part number 42865, a direct-fit replacement for the 2007-2014 Ford Edge and 2007-2015 Lincoln MKX. This rear wiper arm holds the blade against the rear window with spring pressure and carries it across the glass as the wiper motor drives the pivot.
Signs this part may need replacing include a blade that no longer presses firmly on the rear glass, streaks or missed areas after a wipe, an arm that is bent out of shape, or an arm that sits loose on its pivot. Because streaking can also come from a worn blade, check the cause before replacing the arm. See the "Vehicles it fits" section for complete fitment details.

Is this a front or rear wiper arm?
This is a rear wiper arm. It holds the wiper blade against the rear window glass and moves it back and forth as the wiper motor turns the pivot.
What are signs a rear wiper arm may need replacing?
Common signs include weak blade pressure on the glass, streaking or missed areas, an arm bent from snow or ice, or an arm that is loose on its pivot. A worn blade can also cause streaks, so check both.
How is this wiper arm installed?
It replaces the original arm at the rear wiper pivot. Follow your vehicle's service information for the removal steps, arm position on the glass and fastener torque.
Why do wiper arms fail?
Dorman lists spring wear, snow damage and metal fatigue as common reasons an original arm fails. Any of these can reduce the pressure that keeps the blade in contact with the glass.
