Attachment Style

The 2016 Peterbilt 579 typically uses a Hook style attachment for its wiper blades. This is one of the most common and easiest attachment methods, recognizable by the "J" or "U" shape at the end of the wiper arm that hooks into the blade assembly.

How to Install

Replacing the wiper blades on your 2016 Peterbilt 579 is a straightforward maintenance task that you can usually do yourself. Here are the general steps:

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 it snap back against the glass.
2. Remove the Old Blade: Locate the small tab or clip on the wiper blade where it connects to the wiper arm. Press this tab/clip and slide the old blade off the hook of the wiper arm. Some blades may require a slight rotation to release.
3. Attach the New Blade: Slide the new wiper blade onto the hook of the wiper arm. You should hear a click or feel it lock into place. Give it a gentle tug to ensure it's securely fastened.
4. Lower the Wiper Arm: Carefully lower the wiper arm back onto the windshield. Do not let it drop suddenly.
5. Test the Wipers: Turn on your wipers to ensure they are working correctly and providing a clear, streak-free wipe.

Note: While the hook attachment is common, some aftermarket blades may have slightly different locking mechanisms or require an adapter. Always refer to the instructions provided with your new wiper blades if you encounter an unusual attachment style.

When to Replace

Wiper blades are wear-and-tear items that should be replaced regularly to ensure optimal visibility and safety, especially for a vehicle like the Peterbilt 579 that often covers long distances in varying conditions.

• General Interval: A good rule of thumb is to replace your wiper blades every 6 to 12 months, or twice a year, regardless of apparent wear. This proactive approach helps maintain peak performance.
• Streaking: If your wipers are leaving streaks across the windshield, it's a clear sign that the rubber element is worn, cracked, or hardened and needs to be replaced.
• Chattering or Skipping: When the blades jump or bounce across the windshield rather than gliding smoothly, it indicates that the rubber is no longer making proper contact, often due to hardening or a bent wiper arm.
• Squeaking or Squealing: Noisy operation can also be a symptom of worn blades that are not effectively clearing the windshield.
• Cracked or Torn Rubber: Physically inspect the rubber edge of the blade. Any signs of cracks, tears, or missing pieces mean it's time for new blades.
