Back from Minnesota - our trailer limped to the RV dealer (Ballantyne RV) in Victor, NY on 3 tires. We lost a wheel on the fifth wheel on the NYS Thruway. Did not feel a thing when it came off the RV....
I'm wondering if the outer bearing was't worn when it was repacked, and then it got worse and disintegrated. I wonder how long it had been on the trailer?
Was it perhaps a day with a decent side wind? Or in the 6k miles since repack, was there any big side wind days? Its the rear wheel, so it would get more sideways pressure than the front one....at least a little more.
