    Best aftermarket replacements

    For your 2020 Kenworth W900, several premium aftermarket wiper blades offer excellent performance and durability. Here are some top choices, ranging from a rough price tier of average to premium:

    • Bosch ICON: (Premium) Known for their beam blade design and exclusive FX dual rubber, providing consistent clear wipes and extended durability. A great all-weather blade.
    • Rain-X Latitude: (Above Average) Features a contoured beam design for even pressure and a smooth, streak-free wipe. Its synthetic blend rubber is designed to be durable in various conditions.
    • Trico Force: (Above Average) Designed for robust performance, these blades excel in harsh conditions, offering a strong, durable wipe with their all-weather design.
    • Michelin Stealth: (Average) Combines the advantages of a traditional and beam blade, offering good contact with the windshield and consistent wiping performance.
    • PIAA Si-Tech: (Premium) Utilizes silicone-infused rubber for superior wiping performance and longevity, often outlasting conventional blades. They are excellent for repelling water.

    Attachment style

    The 2020 Kenworth W900 typically uses a J-hook attachment style for its wiper blades. This is one of the most common and easiest attachment methods, allowing for straightforward replacement of the blades. Always double-check your specific vehicle's attachment to ensure compatibility, though J-hook is standard for many heavy-duty trucks like the W900.

    How to install

    Replacing the wiper blades on your Kenworth W900 is a relatively simple process. Here are generic steps:

    1. Lift the wiper arm: Gently pull the wiper arm away from the windshield until it locks into an upright position.
    2. Remove the old blade: Locate the small tab or clip where the blade connects to the wiper arm. Press this tab and slide the old blade off the J-hook. You might need to wiggle it a bit.
    3. Attach the new blade: Slide the new wiper blade onto the J-hook until you hear a click or feel it lock into place. Ensure it's securely fastened.
    4. Lower the wiper arm: Gently lower the wiper arm back onto the windshield. Avoid letting it snap back, as this can damage the windshield.
    5. Test the wipers: Turn on your wipers to ensure they are functioning correctly and provide a clear, streak-free wipe.

    Note: While J-hook is standard, if your W900 has an unusual attachment type, consult your owner's manual or a professional for specific instructions.

    When to replace

    Wiper blades are a critical safety component and should be inspected regularly. Generally, it's recommended to replace them every 6 to 12 months, or sooner if you notice any of the following signs:

    • Streaking: If the blades leave lines or streaks on the windshield, they are no longer clearing water effectively.
    • Chattering or skipping: Worn blades can cause the wipers to vibrate or skip across the windshield instead of gliding smoothly.
    • Squeaking or screeching: These noises indicate the rubber is hardened or torn.
    • Reduced visibility: Any decrease in your ability to see clearly during rain or snow is a strong indicator that new wipers are needed.

    Regular replacement ensures optimal visibility and safety, especially important for a vehicle of the Kenworth W900's caliber, which often travels long distances and in varying weather conditions.
