2019 Freightliner M2 106 Wiper Blade Sizes & Replacement Guide

The 2019 Freightliner M2 106 is a rugged and versatile medium-duty truck designed for serious hauling, delivery, and commercial applications. When you are putting heavy miles on your rig, visibility is critical for safety. Over time, exposure to diesel exhaust, road grime, UV rays, and harsh weather will degrade your wiper blades. Replacing them with the correct size and attachment style ensures a clear windshield no matter what conditions you face on your route.

Here is everything you need to know about replacing the wiper blades on your 2019 Freightliner M2 106.

Quick reference

Note: The Freightliner M2 106 does not come equipped with a rear wiper blade. OEM part numbers can vary based on specific fleet configurations, so check with your local Freightliner parts counter if you require genuine factory replacements.

Best aftermarket replacements

If you are looking to upgrade your wiping performance or simply need a quick replacement on the road, several premium aftermarket brands offer compatible 22-inch blades. While some heavy-duty trucks require specialized commercial blades, standard J-hook adapters on these premium lines will often fit standard wiper arms.

• Bosch ICON: Premium tier ($25–$35). Known for its exclusive tension spring arcing technology, creating a custom fit along the curve of the windshield for exceptional all-weather performance.
• Rain-X Latitude: Premium tier ($20–$30). Features a water-repelling coating that transfers to your windshield during use, causing water to bead up and roll off even at highway speeds.
• Trico Force: Mid-to-high tier ($20–$25). Designed with a swept-wing spoiler that utilizes wind force to keep the blade pressed firmly against the glass, making it great for highway driving.
• Michelin Stealth: Mid tier ($15–$25). Features a hybrid design with a hard polymer cover that protects the blade from snow and ice buildup.
• PIAA Si-Tech: Premium tier ($30–$40). Made with high-quality silicone rubber that resists wear and UV degradation much longer than standard rubber blades, while also promoting water beading.

Attachment style

The 2019 Freightliner M2 106 typically utilizes a classic J-hook attachment style. This is the most common wiper arm type in the automotive and light-to-medium truck industry. The wiper arm ends in a hook shaped like the letter "U" or "J," which simply wraps around the mounting pivot inside the wiper blade assembly.

How to install

Installing new wiper blades on your M2 106 is a straightforward process that takes only a few minutes.

1. Lift the wiper arm: Carefully pull the wiper arm away from the windshield until it locks into a standing position. (Be careful not to bump it, as a bare metal arm snapping back can crack the glass).
2. Unlatch the old blade: Locate the small plastic tab or release mechanism where the blade meets the J-hook. Press or squeeze this tab.
3. Slide it off: Push the wiper blade down toward the base of the wiper arm to slide it out of the hook, then pull it completely away.
4. Prepare the new blade: If your new aftermarket blade comes with multiple adapters, ensure the standard J-hook adapter is installed on the blade.
5. Install the new blade: Slide the new blade into the hook until you hear a distinct "click" confirming it is locked securely in place.
6. Lower the arm: Gently lower the wiper arm back onto the windshield. Repeat for the passenger side.

When to replace

For commercial vehicles, visibility is your first line of defense. You should plan to replace your wiper blades every 6–12 months. However, you should swap them out sooner if you notice any of the following symptoms:

• Streaking or smearing: Leaves bands of water across your line of sight.
• Chattering: The blade skips or bounces across the glass, often accompanied by a loud squeaking noise.
• Splitting: The rubber squeegee is visibly peeling or tearing away from the blade frame.
