Purpose and function of the arm

The rear window wiper arm is responsible for precisely pressing the blade against the glass surface and its smooth movement along the arc designed by the manufacturer. In the case of the Mercedes W168 class, the proper fit of this element is important for:

• even collection of water and dirt from the rear window,
• reducing vibration and noise during wiper operation,
• maintaining the correct operating angle relative to the glass surface,
• protecting the drive mechanism from excessive loads.

Thanks to the use of an original arm, the wiper system maintains the parameters intended by Mercedes engineers, which is especially important during daily use of the car in rain, snow, or slush.

Construction and fit for the Mercedes W168

The arm has been designed specifically for the construction of the rear window and trunk lid in the W168 model. This means a properly selected length, profile, and mounting point, which facilitates installation and ensures proper cooperation with the drive mechanism.

Key functional features of this element are:

• dedicated mounting to the rear wiper drive axis,
• profile adapted to the curvature of the rear window,
• stable construction ensuring repeatable blade pressure,
• compatibility with blades intended for this model.

An arm configured in this way reduces the risk of uneven wiping, skipping on the glass, or excessive blade wear, which in practice translates into more predictable and comfortable operation.

Placement on the vehicle and assembly aspects

The element is intended for installation in the rear part of the vehicle, on the axis of the rear window wiper mechanism. A correctly installed arm works with the existing drive without the need for interference with the electrical installation or the structure of the trunk lid.

When replacing, it is worth paying attention to:

• correct setting of the arm's rest position relative to the lower edge of the window,
• proper tightening of the mounting to avoid operating play,
• condition of the mounting socket and the drive axis,
• selection of a wiper blade consistent with the arm's geometry.

This approach allows you to fully utilize the potential of the original arm and maintain the efficiency of the wiper system at a stable level.

Characteristics of the used element

The offered arm comes from the used parts segment, which is a beneficial solution for users looking for original components at a reasonable price. The used element retains its factory design parameters, making it a direct replacement for a worn or damaged arm in your Mercedes.

Choosing an original, used rear wiper arm is a good solution wherever the priority is to maintain compliance with the manufacturer's design while optimizing the costs of vehicle repair or maintenance.
