The threaded portion is inside the barrel and not visible to any visual inspection without totally disassembling the unit. No rotation is possible once the hitch is attached but the rod is rotated every time the end is turned to match the "this end up" label. If that is what backed out the rod, its another poor design feature. I don't plan to do an failure analysis.
Sorry- could've been clearer....I wasn't talking about this latest event.
My post re. bolt torque had to do with the first two times you had problems with the Blue Ox, both of which sound like they were baseplate hold-on bolt related:

..snip..In September 2011, the Blue Ox base plate totally pulled off the jeep while making a slow left hand turn at an intersection in Amarillo, TX. None of the four bolts were found but I suspect the correct locktite may not have been used, even though I was assured it was professionally installed IAW the Blue OX instructions...snip..
In March 2013 arriving at a military RV park in Alamagordo, NM, the entire base plate was ripped off from the Jeep while making a slow left hand turn inside the campground. One bolt was sheared off, two remained tightly bound but ripped a 4” square from the Jeep’s box frame.
