Dorman designed this arm to fit and work like the original on the listed applications, so it serves as a direct replacement when the factory front right arm has worn out.
Signs a wiper arm may need replacing include a blade that lifts off or chatters across the glass, streaks left in the swept area, or an arm that is bent or loose on its pivot. A worn blade can cause similar symptoms, so check the cause before replacing the arm.
