Review on 🔒 Pair Locking Hubs for 2004-2015 Ford F150, 2003-2015 Ford Expedition, 2006-2008 Lincoln Mark LT, 2003-2015 Lincoln Navigator | Replaces 600-105 7L1Z3C247A (2 PCS) by Carlos Burrows

I ordered two of these first to replace both sides. When tested on the workbench upon arrival, only one worked properly. Defective returned, replacement sent. The replacement was also defective. So, I have one of the three that took and held vacuum. Defects lost the vacuum fairly quickly. Now I have a good one installed on the passenger side of my truck. It works fine but I'm nervous about how long it will last.
