Variations to watch for
Some regional specifications or special editions may use slightly different front blade lengths. If in doubt, check the manual or pull one blade off to measure it directly.
Rear Wiper Blade Size
Rear blade sizing for the 2018 Grand Cherokee is typically:
- Rear blade: 12 inches
Note: A minority of early or region-specific configurations may use an 11-inch rear blade. If your rear blade looks unusually long or short, confirm the size by measuring or consulting the manual or a parts lookup for your exact VIN.
Rear blade compatibility notes
When shopping for a replacement, ensure you buy the correct rear blade type and connector for your vehicle, as some rear blades use a different mounting style than the front blades.
How to Verify and Replace
How to verify for your exact vehicle and replace blades:
- Check the owner's manual or dealer specifications for the exact blade lengths.
- Inspect the current blades to read any size markings or packaging if you kept it.
- Measure the blade length: extend the blade and use a ruler or tape measure from the mounting point to the tip.
- Confirm adapter compatibility: most front blades use a universal adapter with a hook-style or pin-style mount; ensure the replacements match your wiper arms.
- When buying, consider climate needs (winter blades vs. all-season) and replace both front blades if one is worn to maintain even wiping performance.
Installation is usually straightforward: lift the old blade, release the connector, slide on the new blade, and confirm the arm locks into place. If you encounter resistance or fit issues, consult the owner’s manual or seek help from a professional.
