Purpose and function in the vehicle

The arm is designed for installation in the rear part of the body, where it is responsible for transferring movement from the drive mechanism to the wiper blade. Thanks to its precise geometry and proper pressure against the glass, this component helps maintain even contact between the blade and the glass surface, which translates into a clear field of vision for the driver when reversing and maneuvering. Its placement at the rear of the vehicle means the arm operates in demanding conditions – it is exposed to dirt, road salt, and temperature changes. A properly selected component from this group helps reduce vibrations, blade skipping, and uneven wiping of the glass.

Benefits of using an original Ford arm

Using an arm dedicated to the Ford Tourneo Custom ensures:

• secure fitment to the tailgate mount,
• correct operating angle relative to the glass,
• stable blade pressure along the entire length of its stroke,
• consistent appearance with other body components. As a result, the user gains efficient rear wiper operation and predictable system behavior in difficult weather conditions. A properly selected arm reduces the risk of excessive blade wear and also decreases the load on the drive mechanism.

Characteristics of the used component

The offered component comes from the segment of used original Ford parts. Such elements are frequently chosen by users looking for a reasonable compromise between cost and fitment quality. The arm maintains a construction consistent with the manufacturer's factory specifications, which facilitates installation and subsequent operation. In the case of wiper arms, it is particularly important to maintain proper rigidity and geometry – a used original element allows these parameters to be maintained at a level close to factory standards, without the need for adaptations or modifications.

Installation and service application

The Ford Tourneo Custom Rear Tailgate Window Screen Wiper Arm is intended for direct replacement of the factory component. In a typical service scenario, the replacement involves:

• removing the old arm from the drive axle,
• checking the condition of the mount and thread,
• installing the new arm while maintaining the correct resting position,
• checking the range of motion and blade pressure against the glass. An operation performed in this way allows for restoring the correct operation of the rear wiper, which is important for both driving comfort and safety when reversing in rain or snow.

Expanding service in the area of Ford wipers
