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 had the same thing happen about 2 years ago. The outer wheel bearing failed. It had been serviced about 12 months prior. I replaced the axel and all of the tires. The tires were Michelin Ribs that were 6 years old, so it was time anyway. The bearings that come on the axels are made in China. I was able to get replacements made in the USA by Timken.
