Review on 🚛 Mile Marker 549 Premium Manual Locking Hubs for 2005 & Newer Super Duty Ford Trucks (F-250, F-350, F-450, F-550) by Charley Martinez

They look strong and durable. Since I haven't tested them yet, I can't say anything positive. I care for her. They are difficult to operate manually. One or the other will usually lock on the first try, but to lock the other you have to put the truck in neutral and then rock it back and forth until it locks. I called the manufacturer (left a message) and then emailed them for my opinion. No reply for over 2 weeks.
