The Definitive 2017 Jeep Wrangler Rear Wiper Blade Size

Let’s get straight to the most common question: “What’s the 2017 Jeep Wrangler rear wiper blade size?” For your 2017 Jeep Wrangler JK or JKU (2-door or 4-door), the standard rear wiper blade size is typically 16 inches (approximately 400mm). This is a pretty consistent measurement across the JK generation.

While 16 inches is the general consensus, it’s always a good idea to double-check. Wiper blade manufacturers sometimes have slight variations, or you might find a specific brand that recommends a slightly different fit for optimal contact. However, for 99% of 2017 Wrangler owners, a 16-inch blade will be your go-to.

Why the Right Size Matters

You might think an inch or two won’t make a difference, but when it comes to wiper blades, precision is key. Using the correct 2017 Jeep Wrangler rear wiper blade size ensures:

  • Optimal Coverage: A blade that’s too short will leave unwiped areas, creating blind spots. Too long, and it might hit the window trim or even another wiper arm, causing damage or ineffective wiping.
  • Even Pressure Distribution: Correctly sized blades apply even pressure across the entire length of the blade, ensuring a clean, streak-free wipe.
  • Longevity: Blades that are too long or too short can be stressed, leading to premature wear and tear on both the blade and the wiper motor.
  • Reduced Noise: An ill-fitting blade can chatter, squeak, or groan, turning a minor annoyance into a major distraction.

OEM vs. Aftermarket Options

When you’re ready to replace your blade, you’ll encounter two main categories: Original Equipment Manufacturer (OEM) and aftermarket.

  • OEM Blades: These are the blades designed and supplied by Mopar, Jeep’s official parts division. They are guaranteed to fit perfectly and are often made to high quality standards. The downside? They can be more expensive.
  • Aftermarket Blades: A vast array of brands like Bosch, Rain-X, PIAA, Trico, and Michelin offer blades for your Wrangler. These can range from budget-friendly options to premium silicone or beam blades. Aftermarket blades often offer innovative designs, such as beam blades for better pressure distribution or specialized coatings for water repellency.

Our advice? Don’t be afraid of aftermarket options, but stick to reputable brands. Read reviews and consider what features are important to you, especially if you spend a lot of time on trails.

How to 2017 Jeep Wrangler Rear Wiper Blade Size: A Step-by-Step Installation Guide

Replacing your rear wiper blade is one of the easiest DIY tasks you can do on your Wrangler. It requires minimal tools and can be done in minutes. This section serves as your comprehensive “how to 2017 Jeep Wrangler rear wiper blade size” guide.

Tools and Supplies You’ll Need

Gathering your tools beforehand makes the job quicker and smoother.

  • New 16-inch rear wiper blade (make sure it’s the correct type for your Wrangler’s arm attachment).
  • Clean rag or microfiber towel.
  • Window cleaner (optional, for a sparkling finish).
  • Small flathead screwdriver or trim removal tool (only if the old blade is stubborn or has a cover).

Pro Tip: Always have a new blade ready before you remove the old one. You don’t want to be caught without a functional wiper, especially if unexpected weather rolls in.

The Quick Swap Procedure

Follow these simple steps to replace your rear wiper blade:

  1. Lift the Wiper Arm: Gently pull the rear wiper arm away from the glass until it locks into an upright position. Some Jeep arms have a small tab you might need to press to release it from the glass.
  2. Examine the Attachment Point: Most 2017 Jeep Wranglers use a hook-style attachment for the rear wiper. There might be a small plastic clip or cover over the hook.
  3. Remove the Old Blade:
    • If it’s a hook style: Orient the blade so the hook is visible. You’ll usually find a small tab on the blade where it connects to the arm. Press this tab and slide the blade down and off the hook. It might require a little wiggle.
    • Some blades have a small locking pin or button; press or pull it to release.

    Safety First: Be careful not to let the wiper arm snap back onto the glass without a blade attached. It can chip or crack your rear window. Hold onto the arm firmly.

  4. Clean the Wiper Arm: While the blade is off, take a moment to wipe down the wiper arm with your rag. Remove any dirt, grime, or corrosion.
  5. Install the New Blade:
    • Align the new 16-inch blade with the hook on the wiper arm.
    • Slide the new blade onto the hook until you hear or feel a click, indicating it’s securely locked in place. Give it a gentle tug to confirm it’s seated properly.
  6. Gently Lower the Arm: Carefully lower the wiper arm back onto the glass.

Post-Installation Checks

Once your new blade is installed, perform a quick check to ensure everything is working correctly:

  • Visual Inspection: Make sure the blade sits flush against the glass.
  • Test Run: Turn on your rear wiper (with plenty of washer fluid!) and observe its operation. It should move smoothly and wipe cleanly without streaking or chattering.
  • Listen: A properly installed blade should operate quietly.

If you notice any issues, re-check the installation. Sometimes, the blade isn’t fully seated on the hook. If problems persist, ensure you have the correct 2017 Jeep Wrangler rear wiper blade size and type.

Benefits of Maintaining Your 2017 Jeep Wrangler Rear Wiper Blade

Regular maintenance of your rear wiper blade isn’t just about avoiding a quick fix; it’s about a range of significant benefits that enhance your driving experience and safety, especially for off-road enthusiasts.

Enhanced Safety and Visibility

This is the most critical benefit. A clean, properly functioning rear wiper ensures you have an unobstructed view of what’s behind you. This is vital for:

  • Backing Up: Whether you’re navigating a tight parking spot or reversing on a tricky trail, clear rear visibility prevents accidents.
  • Lane Changes: Quickly checking your blind spots and the lane behind you is safer with a clear rear window.
  • Off-Roading: Dust, mud, and water splashes are constant companions on the trail. A good rear wiper helps you keep an eye on your convoy, obstacles, or approaching conditions.
  • Inclement Weather: Rain, snow, and slush can dramatically reduce visibility. A reliable wiper cuts through it all.

Protecting Your Investment

Believe it or not, a neglected wiper blade can cause more than just streaks. A worn-out blade can:

  • Scratch Your Glass: If the rubber element degrades and exposes the metal or plastic frame, it can scratch or pit your rear window, leading to costly repairs.
  • Overwork Your Wiper Motor: A blade that drags or sticks can put undue strain on your wiper motor, potentially leading to premature failure. Replacing a motor is a much bigger job and expense than replacing a blade.

Eco-Friendly Wiper Blade Choices

As off-roaders and outdoor enthusiasts, we often have a heightened awareness of our environmental impact. When considering the 2017 Jeep Wrangler rear wiper blade size and type, you can make eco-conscious choices:

  • Long-Lasting Blades: Investing in higher-quality, durable blades (like silicone) means less frequent replacements, reducing waste.
  • Recycling: Some auto parts stores and recycling centers accept old wiper blades. Inquire locally about recycling programs for rubber and metal components.
  • Blade Refills: A truly sustainable option is to find blade refills for your existing wiper frame. This significantly reduces plastic and metal waste. While less common for rear wipers, it’s worth checking if available for your specific arm type.
  • Proper Disposal: If recycling isn’t an option, dispose of old blades responsibly according to local waste management guidelines.

Common Problems with Your 2017 Jeep Wrangler Rear Wiper Blade and How to Fix Them

Even with the correct 2017 Jeep Wrangler rear wiper blade size, issues can arise. Understanding common problems and their solutions is part of being a savvy DIYer.

Streaking and Skipping

This is arguably the most common complaint and often the first sign of a problem.

  • Cause: Worn-out rubber, dirt/grime on the blade or windshield, bent wiper arm, or improper blade contact.
  • Fix:
    • Clean the Blade: Wipe the rubber edge of the blade with a clean cloth soaked in rubbing alcohol or a mild detergent.
    • Clean the Windshield: Give your rear window a thorough cleaning to remove road film, wax residue, or tree sap.
    • Replace the Blade: If cleaning doesn’t help, the rubber is likely hardened or torn. Time for a new 16-inch blade.
    • Check Wiper Arm: Gently lift the arm and check for any bends or damage. A bent arm might not apply even pressure.

Noisy Operation (Chattering or Squeaking)

A noisy wiper is irritating and indicates a problem.

  • Cause: Dry windshield, worn blade, incorrect blade angle, bent wiper arm, or loose mounting.
  • Fix:
    • Use Washer Fluid: Never run your wipers on a dry windshield. Always use plenty of washer fluid.
    • Replace Blade: A hardened or torn blade will chatter.
    • Check Blade Angle: The blade should be perpendicular to the glass. If it’s angled incorrectly, it can skip. This might require gently twisting the wiper arm (be very careful not to overdo it!).
    • Inspect Arm: Ensure the arm isn’t loose at its mounting point.

Wiper Arm Issues

Sometimes, the blade isn’t the problem; it’s the arm.

  • Cause: Loose mounting nut, bent arm, or worn spring mechanism.
  • Fix:
    • Tighten Mounting Nut: At the base of the wiper arm, there’s usually a cap covering a nut. If the arm is wobbly, gently tighten this nut.
    • Straighten Bent Arm: If the arm is visibly bent, you might be able to gently bend it back into shape. This requires a delicate touch; too much force can break it. If severely bent, replacement is best.
    • Worn Spring: If the arm doesn’t apply enough pressure to the glass, the spring might be weak. In this case, the entire wiper arm assembly needs to be replaced.

When in doubt, especially with arm issues, consult a professional. It’s better to get it right than to damage your wiper motor or rear window.

2017 Jeep Wrangler Rear Wiper Blade Size Best Practices & Care Guide

Extending the life of your rear wiper blade and ensuring it performs optimally for longer is simple with a few best practices. This section provides a comprehensive “2017 Jeep Wrangler rear wiper blade size care guide.”

Regular Cleaning and Inspection

Your wiper blade is constantly exposed to the elements. Regular cleaning is paramount.

  • Weekly Wipe-Down: Every time you wash your Jeep, or at least once a week, gently wipe the rubber edge of your rear wiper blade with a damp cloth or a paper towel soaked in windshield washer fluid. This removes grit, grime, and road film that can cause streaking and premature wear.
  • Deep Clean (Monthly): For a deeper clean, use rubbing alcohol on a rag to wipe the blade. This removes stubborn oils and residues.
  • Visual Inspection: While cleaning, run your finger along the rubber edge. Look for cracks, tears, missing pieces, or hardening of the rubber. Also, check the frame for any bends or corrosion.

Winterizing Your Rear Wiper

Cold weather and ice are particularly harsh on wiper blades.

  • Lift Blades in Freezing Conditions: If you expect freezing rain or snow, lift your wiper arm off the glass when parked. This prevents the blade from freezing to the windshield, which can tear the rubber when you try to use it.
  • Defrost Thoroughly: Never use your wipers to scrape ice off the window. Always fully defrost your rear window first. Use your Jeep’s defroster and an ice scraper.
  • Winter-Specific Fluids: Use a high-quality winter windshield washer fluid with de-icing properties.

When to Replace: A Pro’s Schedule

Even with the best care, wiper blades don’t last forever. Here’s a general guideline for replacement:

  • Every 6-12 Months: This is the golden rule. Wiper blades are a wear-and-tear item. Even if they look okay, the rubber can harden and lose its effectiveness over time.
  • At the First Sign of Trouble: If you notice streaking, chattering, or unwiped areas despite cleaning, replace the blade immediately. Don’t wait until visibility is severely compromised.
  • Before Long Trips: If you’re heading out on a major road trip or an off-road adventure, especially into varied weather, it’s a great idea to install fresh blades as a preventative measure.

Think of your wiper blades like your tires – they’re critical safety components that wear out. Don’t skimp on quality or delay replacement.

Upgrading Your Rear Wiper Blade for Off-Road Adventures

For the true FatBoysOffroad enthusiast, standard isn’t always enough. When you’re tackling mud, dust, and grime, a superior rear wiper blade can make a world of difference.

Heavy-Duty Blade Options

While the standard 2017 Jeep Wrangler rear wiper blade size remains 16 inches, you can upgrade the type of blade:

  • Beam Blades: These modern blades don’t have an exposed metal frame. Instead, they feature a tensioned steel beam inside the rubber, which applies more uniform pressure across the entire blade. This results in better wiping, especially in heavy rain or snow, and they are less prone to ice buildup.
  • Silicone Blades: Premium silicone blades tend to last longer than traditional rubber blades and can even lay down a water-repelling layer on your glass over time. They perform exceptionally well in extreme temperatures and offer superior streak-free wiping. Brands like PIAA are well-regarded for their silicone offerings.
  • Armored/Hybrid Blades: Some blades feature a robust, aerodynamic cover over a traditional frame. These designs protect the blade from debris, ice, and heavy winds, making them excellent for challenging conditions.

When selecting an upgrade, ensure it’s compatible with your Jeep’s wiper arm attachment. Most heavy-duty blades are designed for universal fitment or come with multiple adapters.

Why Off-Roaders Need the Best

For those who venture off the beaten path, a high-performing rear wiper is non-negotiable:

  • Mud & Dust Management: Trails often mean mud splashes and clouds of dust. A superior blade can quickly clear your rear window, allowing you to see obstacles, trailing vehicles, or your spotter.
  • Water Crossings: After a water crossing, your rear window can be completely obscured. A powerful, efficient wiper is essential for regaining visibility immediately.
  • Changing Conditions: Off-roading can take you through diverse environments and sudden weather changes. A reliable blade ensures you’re prepared for anything.
  • Convoy Safety: Maintaining visual contact with the vehicles behind you in a convoy is critical for safety and communication.

Don’t let a cheap, worn-out rear wiper compromise your off-road fun or, more importantly, your safety. Invest in a quality blade that can handle the rigors of the trail.

Frequently Asked Questions About Your 2017 Jeep Wrangler Rear Wiper Blade

We’ve covered a lot, but here are some quick answers to common questions about your 2017 Jeep Wrangler rear wiper blade size and related topics.

Can I use a different size blade than 16 inches for my 2017 Jeep Wrangler rear wiper?

While 16 inches is the recommended size for optimal performance and fit, some owners report success with 15-inch or 17-inch blades depending on the brand. However, sticking to the standard 16-inch size is your best bet to avoid issues like hitting the window trim or leaving unwiped areas. Always verify fitment with the manufacturer’s guide.

How often should I replace my 2017 Jeep Wrangler rear wiper blade?

As a general rule, you should replace your rear wiper blade every 6 to 12 months, or at the first sign of streaking, chattering, or reduced visibility. Harsh weather conditions, frequent use, and exposure to UV rays can accelerate wear.

What’s the difference between conventional, beam, and hybrid wiper blades?

Conventional blades have a metal frame with several pressure points. Beam blades have a tensioned steel beam for more uniform pressure and are less prone to ice buildup. Hybrid blades combine the aerodynamic cover of a beam blade with the robust structure of a conventional frame, offering a blend of performance and durability.

My new blade is still streaking. What could be wrong?

Even with a new blade, streaks can occur. First, ensure the blade and your rear window are thoroughly clean. Road film or wax residue can cause streaking. Also, check that the wiper arm isn’t bent or damaged, which can prevent proper pressure. Finally, ensure the blade is securely attached to the arm.

Is it safe to go through an automatic car wash with my rear wiper blade?

Generally, yes, but exercise caution. Some car washes, especially those with aggressive brushes, can damage wiper blades or arms. If your blade is already old or the arm is loose, it’s safer to hand wash or avoid the car wash’s rear brush section. Always check for any specific warnings from the car wash operator.

Conclusion: Stay Safe, See Clear, Ride On!

Don’t underestimate the importance of a clear rear view, especially when your adventures take you far from paved roads. Knowing the precise 2017 Jeep Wrangler rear wiper blade size (16 inches, folks!) and understanding how to properly install, maintain, and even upgrade it is a fundamental skill for any Jeep owner.
