Product Description

Dorman 42798 is a steel windshield wiper arm engineered to replace the original front right arm on select Ford and Lincoln vehicles. It measures 21.5 inches, uses an arc profile, and features a hook-style blade end with articulated movement for proper windshield contact. The black semi-gloss finish helps match the appearance of the original component while the specific-fit design supports straightforward replacement on the listed applications. This part cross-references Ford OE numbers FL3Z17526A and JL1Z17526B for the same application.

Common Replacement Reasons

• Wiper arm is bent, loose, or no longer holds proper pressure
• Uneven windshield wiping on the front right side
• Reduced blade contact caused by worn arm tension
• Corrosion or finish wear on the original arm
• Need for a direct replacement on a Ford F-150, F-250 Super Duty, F-350 Super Duty, Expedition, or Lincoln Navigator

Installation Notes

Verify the front right position and confirm the vehicle application before installation. This arm uses a flange nut/spine attachment and is designed for a hook-style wiper blade connection. Transfer or install the correct blade separately, since the wiper blade is not included. Check the cowl area and pivot point for wear before fitting the new arm, and align the arm so the blade rests correctly on the windshield.

Quality Assurance

Dorman designs this replacement wiper arm to match the original fit and function on the specified vehicles and to provide durable, dependable operation in daily use.
