Review on 🔧 Xiaoyudou 600-105 4x4 4WD Hub Lock Actuator Assembly Compatible with Ford F150 2003-2015 Expedition, Lincoln Navigator 2006-2008 & Mark LT - Replaces 7L1Z-3C247-A by Jacob Ferrarini

Everything seemed fine until I went for a test ride. The new one was worse than my old one, which was partially broken. I had to run to the auto parts store and ended up paying about $100 for the Dorman brand and another $50 for the vacuum test kit. Used Vacumm kit for testing Old, Dorman and Xiaoyudou. The old sucked about 10 pounds when it was about 5-8 xiaoyudou when it could hold a vacuum closer to 15. I've attached a left-to-right photo of the old Xiaoyudou sleeping. Notice how tall Xiaoyudou is, not sure if that was part of the problem but definitely didn't work. A Dorman works great so far, 2012 F150 Lariat.
