Review on Genuine 15277756 Rear Window Wiper Arm: High-Quality Replacement for Chevrolet Tahoe, Cadillac Escalade, GMC Yukon (2007-2014) - OEM Blade: 12 by David Pullen

This wiper arm is perfect to replace the rear wiper on my 2013 Chevy Tahoe. It looks and fits exactly like the original it replaced. The exchange took less than 10 minutes. If you have never replaced a wiper arm, there are videos on YouTube showing how to replace and how easy it is. If the wiper arm you are trying to remove has been on for a while, it is most likely corroded and you will definitely need a wiper removal tool. I would have tried for a long time to remove the old wiper arm without the proper tool to remove the old one. I bought this as an example - CARTMAN Battery Bearing Remover Tool https://www.amazon.com/dp/B07TYLZXPK
