Purpose and Fitment for Mercedes W205
The presented wiper arm has been specifically designed for the W205 body style and for installation on the right side of the vehicle, meaning the driver’s side in right-hand drive versions. Its appropriate contouring and working angle are adapted to the curvature of the front windscreen, which reduces blade vibration and improves visibility in rain.
Original Mercedes-Benz OE origin ensures that the factory operating parameters of the wiper mechanism are maintained, including the correct range of motion, park position, and compatibility with the drive arm mount.
Construction and Technical Properties of the Wiper Arm
The wiper arm is made from a durable construction material, selected for its resistance to dynamic loads and weather conditions. The construction ensures:
- stable guidance of the wiper blade across the windscreen surface,
- appropriate pressure along the entire working length,
- correct cooperation with the wiper drive mechanism,
- maintenance of the correct park position relative to the bottom edge of the windscreen.
Thanks to its factory design, the arm works with a dedicated type of wiper blade, which translates to even removal of water and debris, and reduced “skipping” on the windscreen.
Condition, Origin, and Benefits of Using a Used Part
This part comes from the secondary market, allowing for an economical replacement of a damaged or worn arm while maintaining original manufacturing quality. A used wiper arm is a sensible choice wherever precise fitment with the factory mechanism is crucial, and cost control for servicing is also important.
Using an original arm instead of an aftermarket replacement minimizes the risk of problems with operating geometry, collisions with the bonnet or pillars, and incorrect wiper blade pressure against the windscreen, which directly impacts driving safety in adverse weather conditions.
Installation and Operation in the Wiper System
The arm is prepared for installation at the factory mounting point on the wiper mechanism, which facilitates servicing. When replacing, it is recommended to:
- set the mechanism to service position before removing the old arm,
- check the condition of the mounting socket and the drive shaft,
- test the wiper operation after installation – particularly the range of motion and park position.
A correctly selected and installed wiper arm reduces wiper blade wear, improves driving comfort in rain, and lessens the load on the drive mechanism.
