Purpose and fitment

The presented rear wiper arm is dedicated to the Ford Focus Mk2 ST Hatchback model, with its placement on the vehicle in the rear window area. The component's design is consistent with the manufacturer's factory specifications, which facilitates installation in place of the original arm and allows for maintaining the correct wiper operating geometry. Thanks to the retention of factory mounting points and appropriately selected length and kinematics, the arm works with the wiper mechanism in a predictable and repeatable manner, without the need for system modifications.

Construction and technical function

The wiper arm is responsible for transferring motion from the drive shaft to the blade, keeping it under the correct pressure against the glass surface. In practice, this means:

• stable guidance of the blade along the working arc of the rear window,
• even pressure along the entire length of the blade,
• reduction of vibrations and skipping during operation in rain or when dirt is present. The properly designed geometry of the arm helps to reduce blind spots on the glass, which improves driving comfort and visibility in the rearview mirror.

Condition and benefits of using a used part

The item is offered in used condition, which in practice means it comes from disassembly and retains the functionality required for further operation. In the case of wiper arms, it is important that:

• there is no excessive play at the mounting point,
• the arm retains its proper structural rigidity,
• the working surfaces allow for correct blade installation. Using an original, used arm allows you to maintain the consistency of the wiper system with Ford's factory specifications, while simultaneously optimizing service costs.

Why choose Ford Wiper arms

Original Ford Wiper arms are designed for long-term operation in variable weather conditions, while maintaining appropriate resistance to corrosion and mechanical loads. By choosing a product from this brand, you gain:

• factory fitment for a specific vehicle model,
• consistency with other wiper system components,
• predictable behavior during operation. If you are planning a comprehensive repair or upgrade of the rear window visibility zone in your Ford and need other elements from the same group, such as additional arms, mounts, or compatible blade holders, check the available parts in the Ford Wiper arms category.

Technical support and part selection

When selecting a wiper arm for a specific body version, it is important to pay attention to the body type (hatchback) and placement on the vehicle (rear). Proper fitment translates into the correct blade operating angle, no collisions with seals, and effective water drainage from the glass.

Although it concerns a different brand and system, it well demonstrates the approach to verifying compatibility, OEM markings, and installation procedures, which are worth applying also when selecting elements such as a wiper arm.
