2018 Jeep Grand Cherokee Wiper Blade Size

The 2018 Jeep Grand Cherokee, a stalwart of the mid-size SUV segment, continues to be a popular choice for its blend of on-road comfort and off-road capability. Among the routine maintenance tasks owners face, replacing wiper blades is crucial for maintaining visibility and safety. This article dives into the specifics of the 2018 Grand Cherokee's wiper blade sizes, along with related information to help owners and technicians make informed decisions.

Wiper Blade Size Specifics for the 2018 Jeep Grand Cherokee

Knowing the correct wiper blade size is paramount for proper fitment and optimal performance. For the 2018 Jeep Grand Cherokee, the specified wiper blade sizes are as follows:

Driver Side: 22 inches
Passenger Side: 21 inches
Rear Wiper (if equipped): 11 inches

It's important to note that these dimensions apply across all trim levels of the 2018 Grand Cherokee, including the Laredo, Limited, Overland, Summit, and the high-performance SRT and Trackhawk models. While aftermarket options might offer slight variations, sticking to the factory-recommended sizes ensures the blades sweep the windshield effectively without overhanging or interfering with other components.

Understanding Wiper Blade Types and Materials

While size is critical, the type of wiper blade also plays a significant role in performance and longevity. Common wiper blade types include:

Conventional Frame Blades: These are the most common and generally the least expensive. They feature a metal frame with multiple contact points to distribute pressure across the blade.
Beam Blades (also known as flat blades): These blades have a frameless design, using a curved steel strip embedded in the rubber to apply uniform pressure. They tend to perform better in snow and ice and often last longer than conventional blades.
Hybrid Blades: These combine features of both conventional and beam blades, offering improved performance and durability at a mid-range price point.

The materials used also influence performance. Most wiper blades are made from rubber, but the quality and type of rubber vary significantly. Some blades use natural rubber, while others use synthetic rubber or silicone. Silicone blades generally offer superior durability and resistance to temperature extremes, translating into a longer lifespan.

Choosing the Right Wiper Blades

Selecting the best wiper blades for your 2018 Grand Cherokee involves considering several factors, including your budget, driving conditions, and desired performance. For areas with frequent snow or ice, beam blades are generally recommended. If cost is a primary concern, conventional blades are a viable option. Reading online reviews and comparing different brands can help you make an informed decision. Some popular brands known for quality include Bosch, Rain-X, and Trico.

Replacing Your Wiper Blades: A Step-by-Step Guide

Replacing wiper blades on a 2018 Grand Cherokee is a relatively straightforward process that most owners can handle themselves. Here’s a general guide:

Lift the wiper arm away from the windshield.
Locate the release tab or clip on the wiper blade. This mechanism varies depending on the blade type.
Press or disengage the release mechanism and slide the old blade off the arm.
Slide the new blade onto the arm until it clicks or locks into place.
Carefully lower the wiper arm back onto the windshield.
Repeat the process for the other wiper blade.

Always test the new wiper blades by activating the windshield wipers and spraying washer fluid to ensure proper operation.

Maintenance Tips for Extending Wiper Blade Life

To maximize the lifespan of your wiper blades, consider these tips:

Clean your windshield regularly. Dirt, debris, and bug splatters can accelerate wear and tear.
Use windshield washer fluid. Avoid using plain water, as it doesn't provide adequate lubrication and can freeze in cold weather.
Inspect your wiper blades periodically. Look for signs of damage, such as cracks, tears, or hardened rubber.
Park in the shade whenever possible. Exposure to direct sunlight can degrade the rubber over time.

Troubleshooting Common Wiper Blade Problems

Common issues with wiper blades include streaking, skipping, and chattering. Streaking often indicates that the blade is dirty or worn. Skipping can be caused by a bent wiper arm or a contaminated windshield. Chattering is typically a result of improper installation or worn wiper blades. Addressing these issues promptly will help maintain clear visibility and prevent damage to the windshield.

Conclusion

Maintaining clear visibility is paramount for safe driving, and properly sized and functioning wiper blades are essential for achieving this. By understanding the correct wiper blade sizes for your 2018 Jeep Grand Cherokee, selecting the right type of blade for your needs, and following proper maintenance practices, you can ensure optimal performance and longevity. Remember to consult your owner's manual for specific recommendations and always prioritize safety when performing any maintenance task on your vehicle.
