Detailed Description

This rear wiper arm is engineered for the Jeep Grand Cherokee WK and Jeep Grand Cherokee rear wiper position across the listed model years. Dorman 42871 is shaped to follow the original equipment layout, helping restore proper rear blade placement and sweep on vehicles that use a rear-mounted wiper arm. The 12.1-inch length and specific-fit design support correct alignment with the rear glass, while the black finish maintains a factory-style look. This part cross-references OE number 68079868AA for the same application.

What It Helps Fix

• Rear wiper arm that no longer holds the blade in the correct position
• Wiper arm damage from wear, corrosion, or impact
• Poor rear glass coverage caused by a bent or loose arm
• Improper blade engagement at the snap-in end
• Loss of rear visibility due to a failing wiper arm assembly

Installation Notes and Tips

Fits 2011-2021 Jeep Grand Cherokee, rear. Fits 2022 Jeep Grand Cherokee WK, rear. Confirm the rear wiper arm style and mounting point before installation, and transfer the existing blade if it matches the snap-in connection used by the vehicle.
