Attachment style

The 2014 Peterbilt 389 typically uses a Hook attachment style for its wiper blades. This is one of the most common and straightforward attachment methods, making replacement relatively easy. Ensure that any aftermarket blades you purchase are compatible with this attachment type.

How to install

Replacing the wiper blades on your 2014 Peterbilt 389 is a simple process that can be done with basic tools or even just your hands. Here are the general 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 wiper blade connects to the arm. Press this tab or lift the clip, then slide the old blade off the hook of the wiper arm.
3. Attach the new blade: Slide the new wiper blade onto the arm's hook until you hear a click or feel it lock into place. Give it a gentle tug to ensure it's securely fastened.
4. Carefully lower the arm: Gently lower the wiper arm back onto the windshield. Do not let it snap down as this can damage the windshield.
5. Test the new blades: Turn on your wipers to ensure they are functioning correctly and providing a clear, streak-free wipe.

Note: While most blades for the Peterbilt 389 use a hook attachment, always refer to the specific instructions provided with your new wiper blades, especially if they have an unusual or less common attachment mechanism.

When to replace

Wiper blades are wear items and their performance degrades over time due to exposure to UV rays, extreme temperatures, and general use. It's generally recommended to replace your wiper blades every 6 to 12 months, or at the first signs of wear and tear. Key indicators that it's time for new blades include:

• Streaking: If the blades leave lines of water or grime on the windshield, they are no longer effectively clearing the surface.
• Chattering or skipping: A chattering noise or a blade that skips across the windshield indicates hardening or damage to the rubber, preventing smooth operation.
• Squeaking: Persistent squeaking can be a sign that the rubber is no longer pliable or that the blade is not making proper contact.
• Visible damage: Cracks, tears, or missing pieces of rubber are clear signs that the blades need immediate replacement.

Ignoring these signs can compromise your visibility and safety on the road. Regular inspection and timely replacement of your wiper blades are essential for maintaining clear vision in all weather conditions.
