Quick reference

Best aftermarket replacements

For your 2018 Jeep Grand Cherokee, several premium aftermarket wiper blade options offer enhanced performance and durability. While prices can vary, here's a general idea of their tier:

• Bosch ICON: (Premium) Known for their beam blade technology and all-weather performance, offering a long lifespan and quiet operation.
• Rain-X Latitude: (Mid-Premium) Features a co-extruded squeegee for smooth, streak-free wipes and an aerodynamic spoiler to prevent lift-off at high speeds.
• Trico Force: (Mid-Range) Designed with a vented spoiler to keep the blade firmly on the windshield, providing consistent contact and clear visibility.
• Michelin Stealth: (Mid-Range) Combines the superior wiping performance of a traditional blade with the aerodynamic properties of a beam blade for year-round effectiveness.
• PIAA Si-Tech: (Premium) Utilizes silicone technology for extended durability, quiet operation, and excellent water-repellency, often costing a bit more but lasting longer.

Attachment style

The 2018 Jeep Grand Cherokee primarily uses a Pinch Tab style attachment for its front wiper blades. This is a common and secure attachment method. The rear wiper blade typically uses a more Specific attachment designed for the rear arm, which may vary slightly in design.

How to install

Replacing your wiper blades is a straightforward maintenance task you can do yourself. Here are the generic steps:

1. Lift the wiper arm: Gently pull the wiper arm away from the windshield until it locks into an upright position.
2. Remove the old blade: Depending on the attachment style (Pinch Tab in this case), you'll typically find a small tab or button to press or a lever to lift. Once disengaged, slide the old blade off the arm.
3. Attach the new blade: Align the new wiper blade with the wiper arm. For Pinch Tab, slide the blade onto the arm until you hear a click or feel it lock into place. Ensure it's securely fastened.
4. Lower the wiper arm: Gently guide the wiper arm back to its resting position on the windshield.
5. Test the wipers: Turn on your wipers briefly to ensure they operate correctly and smoothly.

Note: For the rear wiper or any unusual attachment types, consult your vehicle's owner's manual or refer to instructions provided with your new wiper blades for specific guidance.

When to replace

Wiper blades are crucial for safe driving visibility and should be replaced regularly. Here are some indicators and recommendations for replacement:

• Time: As a general rule, it's recommended to replace wiper blades every 6 to 12 months, regardless of visible wear. The rubber degrades over time due to exposure to UV light, extreme temperatures, and environmental contaminants.
• Streaking: If your wipers leave streaks or lines across the windshield, it indicates the rubber edge is no longer making full contact with the glass, likely due to wear or damage.
• Chattering or skipping: A chattering or skipping sound and motion during operation suggest the blade is not moving smoothly across the windshield. This can be caused by a hardened rubber, dirt buildup, or improper blade angle.
• Squeaking: Persistent squeaking noises also point to issues with the blade effectively cleaning the windshield.
• Cracked or torn rubber: Visible damage to the rubber element of the wiper blade is a clear sign that replacement is needed immediately.

Don't wait until your visibility is compromised in bad weather. Proactive replacement ensures clear vision and safer driving conditions.
