2018 Ford Explorer Rear Wiper Replacement – Restore Rear Visibility
Changing the rear wiper on your 2018 Ford Explorer is a quick DIY task that requires no special tools and only about five minutes of your time. By removing the protective plastic cap and swapping the 11-inch blade, you can eliminate streaks and ensure a clear view of the road behind you.
Do you struggle to see through your liftgate window during a heavy downpour or a dusty trail ride? Most drivers neglect the back window until the rubber is shredded and scratching the glass.
Performing a 2018 ford explorer rear wiper replacement is a simple maintenance task that saves you a costly trip to the dealership. It ensures your safety and keeps your vehicle looking well-maintained.
In this guide, I will walk you through the exact process, from choosing the right blade to avoiding the common mistakes that break the wiper arm. Let’s get your Explorer ready for the road ahead.
Understanding the Unique Design of the Explorer Rear Wiper
The 2018 Ford Explorer features an integrated rear wiper design that is slightly different from the front windshield wipers. The arm is shorter and often partially tucked under the rear spoiler for aerodynamic efficiency and a cleaner look.
Unlike the front wipers, which use a standard J-hook or pin-and-tab system, the rear wiper utilizes a specific pivot point hidden under a plastic cover. This cover protects the hinge from ice, salt, and debris, but it can be intimidating if you have never removed it before.
Before you start, it is important to know that the rear blade is significantly smaller than the front ones. Using the wrong size can cause the blade to hit the spoiler or fail to clear the entire sweeping path of the glass.
The Importance of Rear Visibility for Off-Roaders
If you take your Explorer off the pavement, the rear wiper becomes even more critical. Mud and dust kick up from the rear tires and coat the liftgate glass almost instantly, blinding your rearview mirror.
A fresh blade with high-quality rubber is essential for clearing thick grime without leaving muddy streaks. For those who frequent the trails, I recommend checking the rear blade every time you rotate your tires to ensure it is still pliable and effective.
Essential Tools and Materials for the Job
One of the best things about this project is that it requires almost no tools. Most owners can complete the entire swap using just their hands, though a small flathead screwdriver can help with the plastic cap.
You will need an 11-inch rear-specific wiper blade. While many brands offer “universal” fits, I highly suggest looking for a blade that specifically lists the 2018 Ford Explorer on the packaging to ensure the mounting clip matches perfectly.
- Replacement Blade: A 11-inch (280mm) rear wiper blade.
- Small Flathead Screwdriver: Only needed if the plastic cover is stuck or frozen.
- Microfiber Cloth: To clean the glass and protect the surface during the swap.
- Glass Cleaner: To remove built-up residue before installing the new rubber.
Choosing Between Silicone and Rubber Blades
Standard EPDM rubber blades are the most common and affordable choice. They perform well in moderate climates but can dry out and crack if your Explorer sits in the intense summer sun for long periods.
Silicone blades are a premium alternative. They last up to twice as long as rubber and leave a thin water-repellent coating on the glass with every swipe. If you live in an area with heavy snow or extreme heat, silicone is a worthwhile investment for your rear window.
Step-by-Step 2018 ford explorer rear wiper replacement
Follow these steps carefully to ensure you do not put unnecessary stress on the wiper motor or the plastic arm assembly. Safety is the priority, so work slowly and keep a firm grip on the arm.
Step 1: Accessing the Wiper Arm
Start with the vehicle turned off and the rear liftgate closed. You will notice a plastic cover at the base of the wiper arm where it attaches to the motor. Gently lift the wiper arm away from the glass until it clicks into the service position.
If the arm feels stiff, do not force it. Sometimes road salt or dirt can build up in the hinge. A quick spray of penetrating oil can help loosen the joint if it hasn’t been moved in years.
Step 2: Removing the Protective Cap
The plastic cap at the base of the arm needs to be pivoted upward. Use your fingers to pull the sides of the cap outward slightly and lift. This will expose the nut and the pivot point where the blade connects.
Be careful not to snap the plastic tabs, especially in cold weather when plastic becomes brittle. If you are working in freezing temperatures, run the rear defroster for a few minutes to warm up the area first.
Step 3: Releasing the Old Blade
Once the cap is out of the way, rotate the wiper blade itself away from the arm. You will feel some resistance, but it should pivot about 90 degrees. Once it reaches that point, give it a firm tug to pop it out of the mounting cradle.
Pro Tip: Once the blade is off, the metal or plastic arm is “naked.” Do not let it snap back against the glass, as the spring tension is strong enough to crack your rear window. Place a folded microfiber cloth on the glass for protection.
Step 4: Installing the New Blade
Take your new 11-inch blade and align the center crossbar with the cradle on the wiper arm. Press it firmly until you hear a distinct “click” or feel it lock into place. Rotate the blade back so it is parallel with the arm.
Lower the arm back down toward the glass gently. Finally, snap the protective plastic cap back into its original position. Give the blade a small wiggle to ensure it is securely seated and won’t fly off during use.
Common Pitfalls and How to Avoid Them
While a 2018 ford explorer rear wiper replacement is straightforward, many DIYers make small mistakes that lead to broken parts. One common issue is buying a blade that is too long, which will hit the top spoiler.
Another mistake is failing to clean the glass before testing the new blade. Dirt trapped under the new rubber can cause immediate micro-scratches on your glass. Always wipe the window down with a high-quality glass cleaner first.
Finally, never “dry wipe” your new blade. Running the wiper on a dry, dusty window creates friction that tears the delicate edge of the rubber. Always use the washer fluid spray when testing your new installation.
What to Do if the Arm is Broken
If you find that the wiper arm itself is cracked or the spring has lost tension, replacing just the blade won’t solve your visibility issues. A weak arm won’t press the blade firmly against the curved surface of the glass.
Replacing the entire arm requires removing the mounting nut under the cap. You may need a small gear puller if the arm is seized onto the motor shaft. If this feels beyond your comfort level, this is the time to consult a professional mechanic.
Maximizing the Life of Your New Wiper Blade
To get the most out of your 2018 ford explorer rear wiper replacement, you need to perform basic maintenance. Every time you wash your car, take a damp cloth and wipe the edge of the wiper blade to remove “road film.”
Road film is a mixture of oil, exhaust soot, and chemicals that builds up on the rubber. If left alone, it hardens and causes the blade to chatter or skip. A clean blade is a quiet blade.
In the winter, never use your rear wiper to clear heavy snow or ice. The weight of the snow can strip the gears in the wiper motor or snap the plastic arm. Use a hand scraper to clear the glass before engaging the wiper.
Checking the Washer Nozzle
The rear wiper works best when paired with plenty of washer fluid. The nozzle on the 2018 Explorer is located near the top of the glass. If you notice a weak stream, the nozzle might be clogged with wax or debris.
You can usually clear a clog using a thin sewing needle or a blast of compressed air. Ensuring a strong spray of fluid will lubricate the blade and prevent the rubber from wearing down prematurely.
Frequently Asked Questions About 2018 ford explorer rear wiper replacement
What size rear wiper blade does a 2018 Ford Explorer use?
The 2018 Ford Explorer uses an 11-inch rear wiper blade. It is specific to the rear assembly, so ensure the packaging explicitly mentions rear fitment rather than a standard front J-hook style.
Can I use a 12-inch blade if the 11-inch is out of stock?
It is not recommended. The clearance between the wiper arm and the rear spoiler is very tight. A 12-inch blade will likely strike the plastic trim at the top of the liftgate, which can damage the wiper motor or the spoiler itself.
Why is my rear wiper leaving a streak in the middle of the glass?
This is usually caused by a loss of tension in the wiper arm spring or a “set” in the rubber blade. If the blade is new, check for any debris trapped in the hinge mechanism that might be preventing it from laying flat against the glass.
How long does a 2018 ford explorer rear wiper replacement take?
For most people, the process takes less than five minutes. It is one of the easiest DIY maintenance tasks you can perform on your vehicle, requiring minimal physical effort and no complex tools.
Final Thoughts on Maintaining Your Explorer
Taking the time to handle a 2018 ford explorer rear wiper replacement yourself is a great way to build confidence in your DIY skills. It’s a small task that yields immediate results in terms of safety and driving comfort.
Whether you are navigating a daily commute in the rain or heading out for a weekend of camping, having a clear view out of your rear window is non-negotiable. Keep a spare blade in your cargo area so you are never caught off guard by a sudden failure.
Now that you have mastered the rear wiper, take a look at your front blades and check your washer fluid levels. Keeping these small systems in top shape ensures your Ford Explorer is always ready for the next adventure. Stay safe and stay visible!
