Third Major Blue Ox Casualty

Bolts that come loose normally do dso because they were under torqued or over torqued and then continued to stretch. My guess on the tear outs being discussed is that the base plate attachment points are being stressed during turns. If a RV has a long over hang it is not unusual for the front tires of the toad to go in to scuff. As the tail swings the arc of the toad becomes tighter than the turn angle available in the steering linkage. When this occurs the load at the base plates increase dramatically. I have seen this scuff scenario a few times in smaller gas stations and it is most likely what is causing the "tear out" issues some RVers complain about.
