F350 Trailer wiring fault when towing my XLR

I also have a 2015 F350 and 2016 XLR Thunderbolt. I had the same exact problem the first year I had the trailer. Pop off your trailer hubs and you'll find one of the brake wires has come out of the wire clip and rubbed itself raw on the hub. I went through all my hubs when this happened, and of course it was the last one of 6 wheels where I found the issue. The wire was pretty badly damaged, so I just installed a new magnet and all was good again. However, at the start of this season, the problem returned. I had a feeling about that one brake wire clip (last wheel on the curbside of the trailer) and sure enough, when I opened it up, the wire had come off the clip again. I probably should have just ordered some new clips, but I just zip tied that sucker to the brake arm inside and it's been fine all summer. While I had it up in the air, I ended up just opening all the hubs up for inspection and repacked the bearings too.
