Finding the correct wiper blade sizes for your 2017 Subaru Outback is a crucial part of routine maintenance for ensuring clear visibility in all weather conditions.

This guide provides all the necessary information to help you choose and install the right blades.

Best Aftermarket Replacements

While OEM blades from a Subaru dealership are always a safe bet, many high-quality aftermarket options offer superior performance and longevity. These blades often feature advanced beam designs and rubber compounds that provide a more uniform wipe and better resistance to the elements. Here are some of the most popular choices:

• Bosch ICON: A premium, bracketless beam blade known for its durability and all-weather performance. It sits at a higher price point but is a favorite among car enthusiasts.
• Rain-X Latitude: Another top-tier beam blade that often incorporates a water-repelling coating to help shed rain, sleet, and snow.
• Trico Force: A robust and high-performance blade designed to withstand high winds and heavy precipitation, making it an excellent choice for drivers in extreme climates.
• Michelin Stealth: A popular hybrid blade that combines the aerodynamic features of a beam blade with the focused pressure points of a conventional one, offering a great balance of performance and price.
• PIAA Si-Tech: A premium silicone blade that lasts longer than traditional rubber and applies a silicone coating to the windshield, which helps repel water for a quieter, smoother wipe.

Attachment Style

The 2017 Subaru Outback uses a J-hook attachment for both the driver and passenger side front wipers. This is one of the most common and straightforward attachment types, characterized by the "J" shape at the end of the wiper arm. The vast majority of aftermarket wipers are compatible with this style, often including a pre-installed adapter.

The rear wiper uses a more specific Roc Lock 2 clip-style attachment. When purchasing a replacement, it is essential to verify that the package includes the correct adapter for this type of arm to ensure a secure and proper fit.

How to Install

Replacing the front wiper blades is a simple task that requires no tools.

1. Lift the Wiper Arm: Gently pull the wiper arm away from the windshield until it locks in the upright position.
2. Release the Old Blade: Locate the small tab on the underside of the connector where the blade attaches to the J-hook. Press this tab and push the blade downwards, away from the hook, to release it.
3. Install the New Blade: Slide the new wiper blade's connector into the J-hook on the arm. Pull it upwards until you hear a distinct "click," which signifies it is locked in place.
4. Lower the Arm: Carefully place the wiper arm back against the windshield.

The rear wiper follows a similar process, but you will need to unlatch the specific plastic cover and clip mechanism. Always consult the instructions included with your new blade for a diagram of the rear attachment.

When to Replace

Wiper blades are made of soft rubber and are constantly exposed to UV rays, ozone, and road grime. For optimal performance and safety, they should be replaced every 6 to 12 months. You should replace them immediately if you notice any of the following signs of wear:

• Streaking: Leaving behind lines or bands of water.
• Chattering: The blade skipping or vibrating across the windshield instead of gliding smoothly.
• Splitting: The rubber squeegee is visibly cracked, torn, or separated from the blade frame.
• Squeaking: A loud, unpleasant noise with every wipe.
