Attachment style

The 2021 Ford F-350 Super Duty utilizes a Pinch Tab attachment style for its wiper blades. This is a common and secure attachment method designed to hold the blade firmly to the wiper arm.

How to install

1. Lift the wiper arm: Gently pull the wiper arm away from the windshield until it locks into the upright position. Be careful not to let the arm snap back against the glass.
2. Remove the old blade: Locate the small tab or button on the wiper blade that connects to the wiper arm. Press this tab and slide the old blade off the arm. You may need to wiggle it slightly to disengage.
3. Attach the new blade: Align the new wiper blade with the hook or attachment point on the wiper arm. Slide the blade on until it "clicks" or locks into place. Give it a gentle tug to ensure it's secure.
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 Pinch Tab attachment is straightforward, always double-check your new wiper blade's instructions, as some aftermarket designs may have slight variations in their installation process.

When to replace

Wiper blades are crucial for safe driving visibility and should typically be replaced every 6 to 12 months, or at the first signs of wear. Here are common indicators that it's time for new blades:

• Streaking: If your wipers leave lines or streaks across the windshield, it means the rubber is worn down or damaged.
• Chattering or skipping: Wipers that bounce or skip across the glass indicate that the rubber has hardened or lost its flexibility.
• Squeaking or screeching: Loud noises during operation often point to a worn or improperly installed blade.
• Reduced visibility: Any decrease in your ability to see clearly during rain or snow is a direct sign that your wipers aren't doing their job effectively.
