OTUAYAUTO Rear Wiper Arm and 14" Blade for JEEP Grand Cherokee 2005-2010 — OE-fit, Durable PBT Construction

OTUAYAUTO's rear wiper arm and 14" blade replace the factory part on 2005–2010 JEEP Grand Cherokee models, restoring reliable rear-window visibility with an OE-fit design.

When the rear wiper on your Grand Cherokee streaks, squeaks, or stops tracking correctly, swapping in a properly matched arm and blade is the quickest fix. This replacement set is built to the original equipment profile (OE 05139836AB / 55156514AC / 5139835AC) so it lines up, mounts, and performs like the part your vehicle was designed for. The set arrives with the arm, plastic cover, and a 14" (360 mm) rubber blade preinstalled for a straightforward, one-time exchange.

How does this replacement match the original equipment?

The OTUAYAUTO set follows the OE geometry and mounting points to ensure proper fit and sweep across the rear glass. Materials and dimensions are selected to meet or exceed OEM specifications so wiping performance and durability are comparable to factory parts. Because it includes the arm, cover, and blade, you avoid compatibility issues from mixing aftermarket components.

• Direct OE reference: 05139836AB and equivalent numbers listed
• 14" (360 mm) blade length tuned for Grand Cherokee rear glass
• Arm designed to match factory pivot and torque requirements

What materials and construction improve wiping performance?

This assembly uses a reinforced PBT blend and precision-cut rubber to deliver a quieter, smoother wipe. The arm uses 100% PBT with 30% Pb for structural strength, while the blade features ABSP rubber with an AAA-level cutting edge for consistent water removal. Those material choices reduce flex, resist weathering, and keep the blade seated against the glass during operation.

• Arm: high-strength PBT blend for corrosion resistance
• Blade: ABSP rubber with precision-cut wiping edge
• Factory-style cover included to protect mounting hardware and improve appearance

How easy is installation and what does the package include?

Installation is designed to be a quick, vehicle-specific swap with no special tools beyond basic hand tools. The set ships with one preassembled wiper arm, one 14" blade, and the decorative cover, so you mount the arm to the existing pivot and secure it per factory torque. If any fitment questions arise, the included design references the OE part numbers to confirm compatibility before you begin.

• Package contents: 1 wiper arm with cover + 1 preinstalled 14" blade
• Simple bolt-on replacement using factory pivot location
• Fits 2005–2010 JEEP Grand Cherokee rear application

Will this set last and what support is available if something goes wrong?

Durability comes from robust plastics and a premium rubber edge; those elements are selected to resist sun, cold, and repeated motion. If you encounter a quality concern, OTUAYAUTO commits to working with you to resolve the issue, whether that means replacement or customer support guidance. Routine inspection and occasional replacement of the rubber edge will maintain peak performance.

• Designed to meet/exceed OEM lifespan under normal use
• OTUAYAUTO customer support available for product issues
• Easy future blade swaps when the rubber edge eventually wears
