Replacing the front wiper blades on a 2017 Subaru Forester is a quick, do-it-yourself task. The two front blades are typically 26 inches on the driver’s side and 17 inches on the passenger’s side. With the right blades and a few simple steps, you can complete the swap in about 10 minutes.
What you’ll need
Gather these items before you start to ensure a smooth replacement.
- Replacement front wiper blades: 26 inches for the driver’s side and 17 inches for the passenger’s side. Beam-style blades are commonly used on Subarus and offer good performance.
- Check the blade packaging or your owner’s manual to confirm exact lengths for your vehicle, in case of model variations or regional specs.
- Optional: gloves and a microfiber cloth to handle blades and wipe the windshield, and a small flat tool if your blades have an extra locking tab.
Having the right blades and basic tools in hand helps ensure a quick, secure install with minimal risk to the windshield.
Steps to replace the front wiper blades
Follow these steps to remove the old blades and install the new ones securely.
- Park the car on a level surface and turn off the engine. Retrieve the windshield wiper arms and gently lift them away from the glass until they stay upright.
- Determine the attachment type at each blade's connection to the arm. Most Forester models use a hook-style adapter; for a hook, press the release tab or lever on the blade and slide it off the arm.
- Remove the old blades by disengaging the blade from the arm, supporting the wiper arm so it does not snap back against the windshield.
- Compare the new blades to the old ones to confirm correct lengths: 26 inches for the driver’s side and 17 inches for the passenger’s side. Align the new blade’s adapter with the arm’s hook and slide it in until you hear or feel a click that indicates a secure fit.
- Gently lower the wiper arms back onto the windshield, one at a time, being careful not to slam them down or let the metal parts contact the glass.
- Repeat the process for the other front blade, ensuring both blades are seated and move freely when activated.
- Test the wipers in a safe, dry test—activate them on a light spray or by dabbing water on the windshield to confirm full coverage and no streaking. If streaks appear, reseat the blades or consider a different blade type or size.
With the blades replaced and properly seated, you should see improved visibility and cleaner wipes in wet conditions.
Rear wiper (optional)
The 2017 Forester also has a rear wiper blade. If you need to replace it, verify the exact length on your model (often around 11 inches) and follow the same general steps: lift the arm, release the blade’s locking tab, slide off, and attach the new blade securely.
Maintenance and safety tips
Regularly inspect blades for nicks, tearing, or hard, glazed rubber. Replace them at least once a year or sooner if you notice streaks or skipping. After installing new blades, avoid leaving them against a dry windshield in high heat, which can cause blade cracking over time.
Summary
Changing the front wiper blades on a 2017 Subaru Forester is a straightforward task that most owners can complete in about 10 minutes. Use 26-inch and 17-inch blades for the driver and passenger sides, respectively, ensure the blades are securely clipped to the arms, test them in a drizzle or spray, and replace any blades showing wear to maintain clear visibility while driving.
