To replace the windshield wipers on a 2018 Ford F-150, install two new blades sized for the truck—typically 22 inches on the driver’s side and 21 inches on the passenger side—then reattach and test for proper contact and parking.
Blade sizes and what you’ll need
Knowing the correct blade lengths and having the right tools on hand makes the job fast and reliable. For the 2018 F-150, the common configuration uses a longer driver-side blade and a slightly shorter passenger-side blade. Always verify by checking the old blades or the owner’s manual if you’re unsure.
- Two replacement wiper blades: driver-side about 22 inches, passenger-side about 21 inches (verify with the old blades or manual).
- Optional: winter blades if you live in snowy or icy climates, or all-weather blades for year-round use.
- Tools and supplies: disposable gloves, a microfiber cloth or glass cleaner for the windshield, and a small flat-head screwdriver or plastic trim tool if the connector is stubborn.
Before buying, note that some aftermarket blade kits list different lengths or connector styles. If you’re unsure, bring the old blades or the VIN information to a parts counter to match the correct sizes and connector type.
Step-by-step replacement
Follow these steps to safely remove the old blades and install new ones. Proper seating and alignment are essential for clear vision and long blade life.
- Park the vehicle on a flat surface, turn off the engine, and gently lift the wiper arms away from the windshield so the blades suspend above the glass.
- Identify the blade connector on the wiper arm and locate the release mechanism (this is usually a small tab or lever).
- Remove the old blade: press or lift the release tab and slide the blade out of the arm’s connector. If your setup uses a hook, rotate or lift the blade away from the arm to free it.
- Prepare the new blade: remove packaging, inspect the connector, and ensure you understand whether the new blade uses a hook, pin, or side-lock attachment.
- Attach the driver-side blade: align the new blade’s connector with the wiper arm and push until it locks in place with a click or secure seat.
- Attach the passenger-side blade: repeat the same process on the other side, ensuring both blades are fully seated and secure.
- Lower the wiper arms back onto the windshield carefully to avoid slapping the glass.
- Test the installation: start the engine, turn on the wipers, and spray water to confirm full contact, even wiping, and proper parking positions. If you notice streaks or chatter, reseat the blade or check the connector.
In case of a mismatch or persistent streaking, double-check blade length and connector type, and ensure you’re not attempting to mount a blade meant for a different vehicle or a non-standard arm configuration.
Maintenance and tips
Regular maintenance helps maximize visibility and blade life. Inspect blades monthly for cracking or hard rubber, replace them every 12 to 24 months depending on climate and usage, and consider winter blades if you experience freezing rain or heavy snow. Keep the windshield clean and remove salt or grime that can rapidly wear the rubber surfaces.
Summary
Replacing the windshield wipers on a 2018 Ford F-150 is a straightforward DIY task. Use the correct blade sizes (typically 22 inches for the driver and 21 inches for the passenger), carefully remove the old blades, snap the new ones into the arms, and test for proper operation. With blades properly installed and maintained, you’ll enjoy clearer visibility in rain, snow, and other weather conditions.
