2022 Freightliner Cascadia — Wiper Blade Sizes

Quick reference

Note: The 2022 Cascadia tractor typically does not have a rear wiper. Some arms may use a J-hook; confirm your arm style before ordering.

Best aftermarket replacements

• Bosch ICON (premium): Excellent wipe quality and longevity; look for 28-inch blades and use the included side-pin or J-hook adapter as needed. Approx. $$$.
• Rain-X Latitude (mid/premium): Beam-style blade with good all-weather performance; 28-inch size. Approx. $$–$$$.
• Trico Force (mid/premium): Aerodynamic beam blade; available in 28-inch with multiple adapters, including side pin. Approx. $$–$$$.
• Michelin Stealth (mid): Hybrid design that handles wind well on highway tractors; 28-inch fitment. Approx. $$.
• PIAA Si-Tech (premium): Silicone-coated beam blade for quiet, durable wiping; 28-inch size. Approx. $$$.

Tip: Many retail beam blades ship with passenger-car adapters by default. For commercial-truck side-pin arms, ensure the package includes a side-pin adapter or purchase a heavy-duty/"fleet" variant from the same brand.

Attachment style

Most 2022 Freightliner Cascadia tractors use a side-pin style wiper arm on pantograph assemblies. However, some builds or replacement arms may be J-hook. Identify your arm before purchase:

• J-hook: The arm ends in a hook (commonly 9x3 or 9x4 mm). The blade slides up into the hook until it clicks.
• Side pin: A metal pin protrudes from the arm into the blade’s side. The blade locks on via a spring clip or latch.
• Push-button: A rectangular top-lock with a button to release the blade; less common on heavy-duty trucks but seen on some aftermarket arms.

If your Cascadia has a side pin, choose blades that specifically include a side-pin adapter in 28-inch length. If it’s a J-hook, nearly all consumer blades will fit directly with the hook adapter installed.

How to install

1. Park safely, set the brake, and switch off power. Lift each wiper arm away from the glass, supporting it to avoid snapping back.
2. Remove the old blade:
   • Side pin: Press the locking tab on the blade adapter and slide the blade straight off the pin.
   • J-hook: Press the release tab and push the blade toward the hook opening to unclip, then slide out.
   • Push-button: Depress the button and pull the blade straight off.
3. Prep the new blade with the correct adapter for your arm type. Confirm it’s firmly attached to the blade body.
4. Install the new blade:
   • Side pin: Align the adapter channel with the pin and push until it clicks/locks.
   • J-hook: Insert the hook through the opening and pull upward until it snaps into place.
   • Push-button: Slide onto the arm until the button clicks.
5. Lower the arms gently and test with washer spray to confirm smooth, quiet operation.

When to replace

Replace wiper blades every 6–12 months, or sooner if you notice:

• Streaking, smearing, or missed areas on the sweep
• Chattering, skipping, or excessive noise at highway speed
• Cracked, torn, or hardened rubber edges
• Uneven pressure or bent blade structure
