Quick Reference

Best Aftermarket Replacements

Replacing your 2021 Subaru Crosstrek's wiper blades is a simple and effective way to maintain visibility and safety in all weather conditions. While OEM blades from Subaru are always a reliable choice, numerous aftermarket options offer excellent performance, often with unique features. Here are some of the best choices, categorized by their general price point:

• Bosch ICON ($$$): Often considered a top-tier blade, the ICON is a beam-style wiper that applies uniform pressure across its entire length. This design minimizes streaking and chattering, providing a clean wipe even at highway speeds. Its advanced rubber compound is designed for long life.

• Rain-X Latitude ($$): This popular beam blade combines a sleek, aerodynamic design with a water-repelling formula. The Latitude blades apply a Rain-X coating directly to your windshield as they wipe, which helps to bead up and repel water, snow, and sleet.

• Trico Force ($$): A rugged and durable beam blade, the Trico Force is designed to perform in extreme weather. It features a robust superstructure for durability and an aerodynamic spoiler to keep the blade firmly planted on the windshield at high speeds.

• Michelin Stealth Ultra ($$): This hybrid blade combines the all-weather performance of a beam blade with the precise pressure points of a conventional blade. The "Smart Hinge" design allows the blade to grip the windshield securely for a clean and quiet wipe.

• PIAA Si-Tech ($$$): The PIAA Si-Tech (Silicone Technology) is another premium option. These flat blades use a silicone rubber compound that is highly resistant to UV rays and heat. A major benefit is that they coat the windshield with a layer of silicone, which causes water to bead up and roll off, improving visibility even when the wipers aren't running.

Attachment Style

The 2021 Subaru Crosstrek uses a standard J-hook attachment for both the driver and passenger side front wiper arms. This is the most common type of wiper arm, shaped like the letter "J" at its end. The wiper blade simply hooks onto this arm and clicks securely into place.

The rear wiper uses a more specific Roc Loc 2 style attachment, which is common on many modern Subarus. This requires a specific adapter that usually comes included with the correct aftermarket rear wiper blade.

How to Install

Replacing the front wipers is a straightforward process:

1. Lift the Wiper Arm: Gently pull the wiper arm away from the windshield until it locks in the upright position. Protect your windshield with a towel in case the arm snaps back.
2. Release the Old Blade: Locate the small tab or button where the blade connects to the J-hook. Press this tab and push the blade down along the arm to unhook it.
3. Install the New Blade: Slide the new wiper blade's adapter onto the J-hook until you hear a distinct "click."
4. Lower the Arm: Gently lower the wiper arm back onto the windshield.

For the rear wiper, the process is similar, but you will need to unclip the specific cover for the Roc Loc 2 attachment before sliding the old blade off and the new one on.

When to Replace

For optimal safety and performance, you should replace your wiper blades every 6 to 12 months. However, this interval can be shorter depending on your climate and how often you use them. You should replace them immediately if you notice any of the following signs of wear:

• Streaking: Leaving lines or streaks of water on the windshield.
• Chattering: The blade skipping or vibrating across the glass.
• Squeaking: A loud, audible noise as the blade moves.
• Cracked Rubber: Visible damage, splitting, or hardening of the rubber edge.
