Dorman - HELP Windshield Wiper Arm P/N:42021
Help keep the rear glass on your 2020-2024 Subaru Outback clear with the DORMAN HELP rear windshield wiper arm, part number 43815. The arm holds the wiper blade against the rear window and carries it through each sweep. It is designed as a direct replacement for the listed Outback applications.
A rear wiper arm uses spring tension to press the blade against the glass. If the original arm has lost tension, been bent, or sits loosely on its pivot, the blade may skip, streak, or miss parts of the window. These are signs the arm may need replacing. A worn blade can cause similar streaking, so inspect the blade as well before you replace the arm.
