Review on 🚗 Premium 4WD Front Auto Locking Hub for Ford F250-F550 Super Duty & Excursion - Upgrade Your Off-Road Experience! by Rick Turner

One of the pairs that arrived did not work at first. I had to disassemble it and send it back. got it working After installation, both did not work on the automatic vacuum system. In the picture I put some cellophane on the end of the hub and you can see how it sucks. So these new hubs are leaking. Thumbs down. A complete waste of time.
