• Description:

  This is a genuine Ford wiper arm nut built on the HN1 base, cataloged under names including Wiper Arm Nut, Pivot Assembly Nut, and Wiper Arm Assembly Nut, used to secure wiper arms to their pivot shafts. Documented applications include Escape, Explorer, Flex, Aviator, MKX, Navigator, Mariner, Monterey, and Mountaineer in outer and inner positions, and because the base number is shared across these platforms this listing should be treated as a multi-vehicle service nut. The nut carries the clamp load that keeps the wiper arm seated on the splined pivot so the arm cannot slip under wiping load. A loose, stripped, or missing wiper arm nut lets the arm shift on the splines or work free, which causes the wiper to sweep out of pattern, chatter, or stop contacting the glass. Because correct seating is essential to wiper function, the OEM nut torqued to specification is the right choice. Confirm the wiper arm hardware callout for your model against your VIN before ordering so the nut matches your pivot. This is a multi-year service part that fits across the model years of the listed Ford applications.
