    Best aftermarket replacements

    For your 2018 Kenworth W900, finding robust and effective wiper blades is crucial for maintaining clear visibility, especially given the demands of heavy-duty trucking. Here are some top aftermarket options:

    • Bosch ICON: (Premium Price Tier) Known for their beam blade technology and all-weather performance, Bosch ICON blades offer excellent durability and a streak-free wipe. They are designed to stand up to harsh conditions, making them a solid choice for commercial vehicles.
    • Rain-X Latitude: (Mid-Premium Price Tier) These beam blades feature a pre-installed adapter for easy installation and a contoured design for even pressure distribution, leading to a clean wipe. The water-repelling coating is an added benefit for truck drivers.
    • Trico Force: (Mid-Range Price Tier) Trico Force blades utilize a strong, aerodynamic design that helps prevent lift-off at highway speeds. They are built for durability and provide good performance in various weather conditions, which is essential for long-haul trucking.
    • Michelin Stealth: (Mid-Range Price Tier) Michelin Stealth wipers combine the advantages of both traditional and beam blades, offering a hybrid design for superior contact with the windshield. They are known for their quiet operation and all-season performance.
    • PIAA Si-Tech: (Premium Price Tier) PIAA Si-Tech blades feature silicone rubber, which provides long-lasting performance and resistance to extreme temperatures. They also create a water-beading effect on the windshield, enhancing visibility.

    Attachment style

    The 2018 Kenworth W900 typically uses a Hook attachment style for its wiper blades. This is one of the most common and straightforward attachment methods, making it easy to find compatible aftermarket replacements and relatively simple to install.

    How to install

    Replacing the wiper blades on your Kenworth W900 is a straightforward task that can significantly improve your visibility and safety. Here's a general guide:

    1. Lift the Wiper Arm: Gently pull the wiper arm away from the windshield until it locks into an upright position. Be careful not to let it snap back against the glass.
    2. Remove the Old Blade: Locate the small tab or clip on the underside of the wiper blade where it connects to the arm. Press or lift this tab and slide the old blade off the arm.
    3. Attach the New Blade: Slide the new wiper blade onto the arm, ensuring the Hook mechanism locks securely into place. You should hear a click or feel it engage.
    4. Lower the Wiper Arm: Carefully lower the wiper arm back onto the windshield. Repeat the process for the other wiper blade.

    Note: While the Hook attachment is common, some aftermarket blades may come with multiple adapters. Ensure you use the correct adapter for your vehicle. If you encounter an unusual attachment or have difficulty, consult your vehicle's manual or the wiper blade's instructions.

    When to replace

    Wipers are critical for safety, so regular inspection and replacement are crucial for your 2018 Kenworth W900. Here are some signs it's time for new blades:

    • General Interval: As a rule of thumb, wiper blades should be replaced every 6 to 12 months, even if they appear to be functioning adequately. Over time, the rubber degrades due to exposure to UV rays, temperature extremes, and road debris.
    • Streaking: If your wipers leave lines or streaks across the windshield, it's a clear sign the rubber is worn, hardened, or torn. This reduces visibility, especially in heavy rain.
    • Chattering or Skipping: When wipers chatter, skip, or vibrate across the windshield, it indicates the blade is not making proper contact with the glass. This can be due to a bent arm, hardened rubber, or improper angle.
    • Squeaking or Screeching: Noisy wipers are annoying and often a sign of worn-out rubber or a dirty windshield. While cleaning the windshield can sometimes help, persistent noise usually means replacement is needed.
    • Visible Damage: Inspect the rubber element for cracks, tears, or missing pieces. Any visible damage will compromise the blade's performance.

    Don't wait until a severe storm to realize your wipers are failing. Proactive replacement ensures you always have the clearest possible view of the road ahead.
