Not locked...the rear is LSD. I have tow hooks on the front...never got them on the back b/c I've been planning on getting a hitch. Seems that hammock gear got in the way of that purchase. The Amsteel was wrapped around the bracket that holds the bumper to the frame, so it was a little stronger than just the bumper. Still...I need to get that hitch put on, and I plan to get a tow hook for the receiver when I finally do.
