Purpose and Fitment

The presented arm has been specifically designed for the rear of the B-Class W245 body, where it is responsible for the wiper's operation on the tailgate. Its placement at the rear of the vehicle ensures the correct geometry for blade pressure against the glass and the proper range of wiper operation. Thanks to its factory origin, key mounting parameters such as angle, arm length, and connection method to the drive mechanism are preserved.

Construction and Technical Function

The tailgate wiper arm in the B-Class W245 performs several important technical functions:

• transfers torque from the drive mechanism to the wiper blade,
• keeps the blade in a stable position relative to the glass,
• ensures even pressure along the entire working length,
• operates in external conditions, exposed to moisture, dirt, and temperature changes.

The appropriate arm construction limits blade vibrations and skips, which translates to uniform water removal from the glass surface. This, in turn, improves rear-view mirror visibility and facilitates precise reversing and parking.

Benefits of Using an Original Arm

Using an original tailgate wiper arm for the B-Class W245 offers a range of practical benefits. Firstly, full compatibility with the factory wiper mechanism is maintained, minimizing the risk of play, noise, or uneven operation. Secondly, proper fit to the rear window shape allows for effective removal of water and mud, which is particularly important in city traffic and during driving in difficult weather conditions.

A used OEM part is also an economical solution for drivers who want to maintain the original vehicle specification without investing in a new component. In many cases, this solution can reduce service costs while maintaining correct wiper system operating parameters.

Practical Application and Installation

The tailgate wiper arm in the B-Class W245 is a consumable part that can eventually suffer from mechanical wear or corrosion, manifesting as uneven blade operation, skipping across the glass, or insufficient pressure. Replacing the arm is a typical service operation, which can be performed in a short time by a workshop or an experienced user.

When selecting a part, it is crucial to rely on the vehicle's identification data and manufacturer's numbers, which facilitates matching the correct arm variant to a specific version of the B-Class W245. This helps avoid installation problems and ensures proper cooperation with the existing rear wiper drive mechanism.
